Web Development with ASP.NET and ASP.NET Core

Web applications are crucial components of the modern internet, allowing users to interact dynamically with data, services, and other users without installing software locally on their machines.

ASP.NET and ASP.NET Core are essential technologies Microsoft provides for developing web applications on the .NET platform. Now, let us explore the key aspects of web development using these frameworks.

Web Application Fundamentals

Client-Server Architecture:

• Client: The end-user interface, typically a web browser like Chrome, Firefox, Safari, or Edge. It sends requests to the server and displays results received from the server.
• Server: Hosts the web application and responds to requests from the client.

HTTP Protocol:

The standard for transferring web content. Clients send HTTP requests, and servers send back HTTP responses.

Front-end and Back-end:

• Front-end: What the user interacts with directly. It’s made up of HTML, CSS, and JavaScript.
• Back-end: The server, databases, and application logic. Popular back-end frameworks include Node.js (JavaScript), Django (Python), C# (Dot Net), and Spring (Java).

Databases:

Store data for web applications. Examples include MySQL, PostgreSQL, MongoDB, and SQLite.

Web Application Frameworks:

ASP.NET or ASP.NET Core to develop Web Applications in .NET Ecosystem.

APIs (Application Programming Interfaces):

Allow different software systems to communicate with each other. RESTful APIs, which use HTTP requests to CRUD (create, read, update, delete) data, are common in web applications.

Responsive Design:

Ensures web applications look and function well across devices of all sizes.

Sessions & Cookies:

Help retain user data and state across multiple pages and visits.

Authentication & Authorization:

• Authentication: Confirming a user’s identity (e.g., through passwords, OTPs, biometrics).
• Authorization: Determining what a user is allowed to access and do.

Security:

Critical in any web application. Topics include SSL/TLS (for encrypted communication), input validation/sanitization (to prevent SQL injection and XSS attacks), and best practices for password storage.

Hosting & Deployment:

After developing a web application, it needs to be hosted on servers so users can access it. Services like AWS, Azure, Heroku, and Netlify facilitate this.

MVC Architecture:

Stands for Model-View-Controller. It’s a design pattern that separates an application into three interconnected components:

• Model: Represents the data and business logic.
• View: Displays the data, the UI.
• Controller: Takes input and converts it to commands for the model or view.

Building Web APIs

Web APIs are vital to modern web applications, enabling communication between client-side and server-side code. ASP.NET Core provides a streamlined approach for building Web APIs, including features like:

• Attribute routing for defining API endpoints
• Model binding and validation for handling request data
• Dependency injection for managing services and dependencies
• JSON and XML serialization for data exchange
• Middleware for customizing request/response pipeline

Data Access with Entity Framework and Entity Framework Core

Data access is a critical aspect of application development, and Entity Framework (EF) and Entity Framework Core (EF Core) simplify this process for .NET developers. Let us explore using EF and EF Core to work with databases.

Database Fundamentals

Before diving into EF or EF Core, it’s essential to have a basic understanding of databases, including:

• SQL and Relational Database Concepts (tables, columns, constraints, rows, keys, indexes, and relationships)
• CRUD Operations (Create, Read, Update, Delete)
• Joins, Transactions, Stored Functions, Stored Procedures, Triggers, etc.

Working with Entity Framework

Entity Framework is an object-relational mapping (ORM) framework that simplifies database access and management by providing a high-level, object-oriented approach to working with databases. Key concepts to learn when working with EF include:

• Modeling: EF (Entity Framework) creates an EDM (Entity Data Model) based on POCO (Plain Old CLR Object) entities with get/set properties of different data types. It uses this model when querying or saving entity data to the underlying database.
• Querying: EF allows us to use LINQ queries (C#/VB.NET) to retrieve data from the underlying database. The database provider will translate these LINQ queries to the database-specific query language (e.g., SQL for a relational database). EF also allows us to execute raw SQL queries directly to the database.
• Change Tracking: EF keeps track of changes that occurred to instances of our entities (Property values) that need to be submitted to the database.
• Saving: EF executes INSERT, UPDATE, and DELETE commands to the database based on the changes that occurred to our entities when we call the SaveChanges() method. EF also provides the asynchronous SaveChangesAsync() method.
• Concurrency: EF uses Optimistic Concurrency by default to protect against overwriting changes made by another user since data was fetched from the database.
• Transactions: EF performs automatic transaction management while querying or saving data. It also provides options to customize transaction management.
• Caching: EF includes the first level of caching out of the box. So, repeated querying will return data from the cache instead of hitting the database.
• Built-in Conventions: EF follows conventions over the configuration programming pattern and includes a set of default rules that automatically configure the EF model.
• Configurations: EF allows us to configure the EF model using data annotation attributes or Fluent API to override default conventions.

Working with Entity Framework Core

Entity Framework Core is an object-relational mapping (ORM) framework that simplifies database access and management by providing a high-level, object-oriented approach to working with databases.

Entity Framework Core (EF Core) is the lightweight, high-performance version of EF designed for .NET Core applications. While EF Core shares many similarities with EF, there are some differences and new features to be aware of, such as:

• DbContext & DbSet
• Data Model
• Querying using Linq-to-Entities
• Change Tracking
• SaveChanges
• Migrations

EF Core includes the following new features which are not supported in EF 6.x:

• Easy Relationship Configuration
• Batch INSERT, UPDATE, and DELETE operations
• In-memory provider for testing
• Support for IoC (Inversion of Control)
• Unique Constraints
• Shadow Properties
• Alternate Keys
• Global Query Filter
• Field Mapping
• DbContext Pooling
• Better Patterns for Handling Disconnected Entity Graphs

Application Architecture and Design Patterns

A solid understanding of application architecture and design patterns is crucial for building scalable, maintainable, and testable .NET applications.

SOLID Principles

The SOLID Design Principles are those used to manage most of the Software Design Problems we, as developers, generally encounter in our day-to-day programming. These design principles are tested and proven mechanisms to make the software designs more understandable, flexible, and maintainable. As a result, if we follow these principles while designing our application, we can develop better applications.

SOLID Design Principles represent five Design Principles that make software designs more understandable, flexible, and maintainable. The Five SOLID Design Principles are as follows:

• Single Responsibility Principle (SRP)
• Open/Closed Principle (OCP)
• Liskov Substitution Principle (LSP)
• Interface Segregation Principle (ISP)
• Dependency Inversion Principle (DIP)

Other Design Principles and Patterns

In addition to SOLID, other important design principles and patterns to be familiar with include:

• GOF 23 Design Pattern
• DRY (Don’t Repeat Yourself)
• KISS (Keep It Simple, Stupid)
• MVC (Model-View-Controller)
• Repository pattern
• Unit of Work pattern

Microservices Architecture

Microservices are a way of breaking large software projects into loosely coupled modules, which communicate with each other through simple Application Programming Interfaces (APIs).

Microservices architecture is one popular approach for building large, complex applications by breaking them down into smaller, independent services. Key concepts to learn in this area include:

• Cloud providers (Azure, AWS, etc.)
• Docker and containerization
• Kubernetes for container orchestration
• Message buses and event-driven architecture
• API gateways and service discovery

Testing and Continuous Integration

Testing is a critical aspect of software development, ensuring the reliability and quality of your code. Now, let us explore various testing techniques and tools for .NET applications.

Unit Testing

Unit testing is a software testing technique where individual units or components of a software application are tested in isolation from the rest of the codebase. The main goal is to validate that each software unit works as intended. Key concepts and tools for unit testing in .NET include:

• Test frameworks (xUnit, NUnit, MSTest)
• Test runners and test explorers
• Asserts and test attributes
• Mocking libraries (Moq, NSubstitute, etc.)

Integration Testing and End-to-End Testing

While unit testing focuses on validating individual units or components in isolation, integration testing and end-to-end testing take a broader view, aiming to detect issues that arise when these units interact or when complete flows are tested in the application.

Integration Testing in .NET

Integration testing is the process of testing interactions between integrated units or components to detect any interfacing issues.

• MSTest: This is Microsoft’s testing framework integrated into Visual Studio. It can be used for both unit and integration testing.
• NUnit: A popular testing framework that supports a range of tests, including integration tests. It’s more flexible than MSTest in some respects and has rich support for data-driven tests.
• xUnit.net: Another testing framework that has gained popularity. Its syntax and approach differ slightly from MSTest and NUnit, but many find it concise and powerful.
• Moq: A mocking framework often used with the above test frameworks. With Moq, you can create mock objects to simulate and verify interactions between objects in integration tests.
• TestServer: Part of the ASP.NET Core framework, TestServer provides a way to host and test your application in memory. It’s useful for integration testing, where you want to test the system’s behavior without launching a full server or hitting a real database.
• Entity Framework In-Memory Database: When using Entity Framework Core, you can replace the real database with an in-memory database for testing purposes. It’s ephemeral and useful for simulating database interactions without side effects.

End-to-End Testing in .NET

End-to-end testing is the process of testing the entire application in a real-world scenario, including its interactions with databases, external services, and other applications.

• Selenium: One of the most popular tools for E2E testing of web applications. Selenium can drive a browser and simulate user interactions, allowing tests to cover real-world scenarios. With .NET, you can use the Selenium.WebDriver NuGet package.
• SpecFlow: Paired with Selenium, SpecFlow allows for Behavior-Driven Development (BDD) in .NET. It lets you write human-readable specifications that get translated into automated tests.
• Playwright for .NET: Microsoft’s Playwright is a newer tool designed for testing web applications by automating browser tasks. The .NET version allows developers to write tests in C#.
• Coded UI Test: A feature of Visual Studio Enterprise, Microsoft’s older tool for GUI testing Windows and Web applications. However, it’s worth noting that Microsoft has deprecated Coded UI Test in favor of other tools and platforms like Selenium.
• Appium: For E2E testing of mobile apps. If you’re developing a Xamarin app, for instance, Appium could be used to simulate user interactions on mobile devices.
• Postman and Newman: While Postman is generally associated with API testing, it’s also useful for E2E testing scenarios that involve API interactions. Newman is the command-line tool for running Postman tests, making it suitable for CI/CD pipelines.

Continuous Integration and Continuous Deployment (CI/CD)

Continuous Integration (CI) and Continuous Deployment (CD) are fundamental practices in modern software development, aiming to improve software quality, speed up the delivery process, and ensure more reliable releases.

• Continuous Integration (CI): CI integrates code changes frequently – ideally several times daily. Every integration is verified by an automated build and test process to detect integration errors early.
• Continuous Deployment (CD): Every change that passes all stages of your production pipeline is released to your users automatically, with no human intervention.

.NET, especially with its evolution into .NET Core and .NET 5+, has been designed to work well in modern CI/CD pipelines. Key concepts and tools for CI/CD in the .NET ecosystem include:

• Build and Deployment Tools (MSBuild, dotnet CLI)
• Version Control Systems (TFS, Git, Azure DevOps)
• CI/CD platforms (GitHub Actions, Azure Pipelines, Jenkins, TeamCity)

Performance Tuning and Optimization

Performance is a crucial aspect of modern applications, and .NET provides various tools and techniques for optimizing your code.

Profiling and Diagnostics

Profiling and diagnostics are crucial for maintaining the performance, health, and reliability of .NET applications. Whether you’re trying to find a memory leak, optimize CPU usage, or understand the behavior of your application under load, .NET provides a suite of tools and libraries to assist.

1. Visual Studio Diagnostics Tools:

The Visual Studio IDE comes packed with a suite of diagnostic tools for .NET developers.

Performance Profiler: Visual Studio’s Performance Profiler offers tools that help diagnose CPU usage, memory usage, GPU usage, and more. It includes:

• CPU Usage: This allows you to see where the most time is spent in your code.
• Memory Usage: Helps identify memory leaks and inefficient memory usage.
• Database: Measures the impact of database calls on performance.

IntelliTrace: A historical debugger that allows you to step back in time to view the state of your application at various points in its execution.

• Redgate ANTS Performance Profiler: Profiles the performance of .NET code, helping locate bottlenecks and optimize CPU and IO performance.
• Redgate ANTS Memory Profiler: Helps locate memory leaks and optimize memory usage in .NET applications.

3. .NET Diagnostics SDK:

.NET 5 introduced the System.Diagnostics namespace and the Diagnostics SDK provide tools to capture traces, collect performance counters, and force garbage collection, among other tasks.

4. Event Tracing for Windows (ETW):

ETW is a high-speed tracing facility provided by Windows and can be used to trace .NET applications, system events, and kernel events. Tools like PerfView leverage ETW to provide detailed performance and diagnostic information.

5. .NET Counters:

Starting with .NET Core 3.0, you can use .NET Counters to get performance metrics via the command line. It’s a performance monitoring tool that delivers real-time performance metrics from a live .NET process.

6. Diagnostic Tools with Azure:

If you’re hosting your application on Azure, there are additional diagnostic tools available:

• Application Insights: A part of Azure Monitor, it provides detailed telemetry, including performance metrics, exception details, and usage patterns.
• Azure Monitor and Log Analytics: Full-stack monitoring, advanced analytics, and intelligent alerts are provided.

7. Windows Performance Monitor (PerfMon):

PerfMon is a tool that allows you to monitor system, application, and network performance. It can gather performance data from .NET applications using performance counters.

8. Windows Performance Analyzer:

Used alongside PerfView or other ETW tools, developers can inspect the detailed trace information to analyze application performance.

Performance Best Practices

In addition to using profiling tools, it’s essential to be familiar with performance best practices for .NET, such as:

• Regular Monitoring: Don’t wait for a problem to arise. Regularly monitor and profile your application, especially after significant changes.
• Isolate Issues: When diagnosing, reproduce the issue in a controlled environment and incrementally isolate the problematic component or code.
• Leverage Metrics: Use metrics from tools like .NET Counters or Application Insights to spot anomalies or degradations in performance over time.
• Continuous Improvement: Use profiling and diagnostic results to refine and optimize your codebase continually.

Security and Cryptography

Security is a critical aspect of application development. Now, let us explore security concepts and techniques relevant to .NET developers.

Authentication and Authorization

Authentication and authorization are essential components of any modern web application’s security strategy, ensuring that users are who they claim to be (authentication) and have the right to perform specific actions or access resources (authorization).

Authentication:

Authentication is the process of verifying the identity of a user, application, or system. In the context of a web application, it often involves confirming the identity of a user by checking their credentials (like username and password) against a data source (like a database). Key concepts and tools in the .NET ecosystem include:

• Forms Authentication: An older mechanism generally used with ASP.NET Web Forms. It authenticates the user by checking credentials against a defined data source and then issues a cookie.
• Windows Authentication: Uses the built-in user account and group system to authenticate users.
• OAuth & OpenID Connect: These are open standards for authentication and authorization. .NET has built-in support for these, especially in ASP.NET Core, using Microsoft.AspNetCore.Authentication namespace.
• Identity Server: A popular OpenID Connect provider that integrates well with .NET applications.
• ASP.NET Core Identity: A complete package that provides authentication using a local database, supporting user registration, password recovery, multi-factor authentication, and more.

Authorization:

Once a user is authenticated, the next step is determining what they can do. This is where authorization comes into play. Key concepts and tools in the .NET ecosystem include:

• Role-Based Authorization: Users are assigned roles, and permissions are granted to these roles. For example, a “Manager” role might have permissions that an “Employee” does not. In ASP.NET Core, this can be easily set up with the [Authorize(Roles = “Manager”)] attribute.
• Claims-Based Authorization: Instead of roles, the user’s capabilities are described using claims. Claims can be more granular and flexible than roles. ASP.NET Core supports this out of the box.
• Policy-Based Authorization: Introduced in ASP.NET Core, policies allow for more complex authorization requirements, combining multiple requirements. For instance, a policy might require a user to be in a particular role and to have a specific claim.
• Resource-Based Authorization: Sometimes, you want to authorize based on a resource. For instance, a user might have permission to edit their own posts but not someone else’s. Resource-based authorization can be implemented using ASP.NET Core’s IAuthorizationService.

Cryptography and Data Protection

Cryptography and data protection are vital in securing sensitive data and ensuring data integrity. .NET provides a comprehensive set of classes and libraries for implementing cryptographic functions and data protection mechanisms.

1. Cryptographic Algorithms:

.NET provides classes to work with a variety of cryptographic algorithms, including symmetric, asymmetric, and hashing algorithms:

Symmetric Algorithms: These use the same key for both encryption and decryption. Examples in .NET include:

• Aes
• DES
• TripleDES
• RC2

Asymmetric Algorithms: These use a public key for encryption and a corresponding private key for decryption. Examples include:

• RSA
• DSACryptoServiceProvider
• ECDsa

Hashing Algorithms: These generate a fixed-size hash from input data. Common algorithms in .NET are:

• SHA256
• SHA384
• SHA512
• MD5 (Note: MD5 is considered insecure and should be avoided in modern applications.)

Digital Signatures: These provide a way to verify the authenticity and integrity of data. In .NET, RSA and DSA can be used for this purpose.

2. Random Number Generation:

RandomNumberGenerator: A base class in .NET that provides cryptographic randomness. It’s more secure than the standard Random class for cryptographic purposes.

3. Secure Password Storage:

Password Hashing: Instead of storing passwords, storing a hash of the password is standard practice. .NET offers the Rfc2898DeriveBytes class (PBKDF2) for this purpose, which also supports generating a salt.

4. Key Storage:

ProtectedData: A simple way to protect data (like encryption keys) for the current user or machine using Windows’ Data Protection API (DPAPI).

5. Data Protection in ASP.NET Core:

ASP.NET Core introduces the Data Protection API, a system for protecting data, including encryption keys and tokens.

• IDataProtector: The primary interface for data protection in ASP.NET Core. With it, you can easily protect data (encrypt) and unprotect data (decrypt).
• Purpose Strings: When using IDataProtector, you can specify a purpose string to ensure data protected for one purpose isn’t improperly used for another.
• Key Management: The Data Protection system automatically manages cryptographic keys, rotating them over time to ensure forward secrecy.

6. Secure Key Exchange:

.NET provides support for cryptographic protocols that allow for secure key exchange, such as:

• ECDiffieHellman: An elliptic curve Diffie-Hellman implementation. It enables two parties to each create a public-private key pair, share the public keys, and then derive a shared secret without transmitting any secret data.

Deploying and Managing .NET Applications

Deploying and managing .NET applications involves a series of steps, from moving the application from a development environment to a production environment, ensuring it’s available for end-users, and maintaining its health and performance over time. Here’s an overview of key aspects to consider:

1. Compilation and Publishing:

• Build: Before deploying, ensure your application is correctly built. .NET provides the dotnet build command for this purpose.
• Publish: Use the dotnet publish command to package your application for deployment. This command prepares the application to run on the target environment by gathering the required files.

2. Deployment Methods:

• Manual Deployment: This involves directly copying the application files and setting them up on the target server. It’s simple but lacks scalability and automation.
• Web Deploy: For ASP.NET applications, Web Deploy is a tool that enables automated deployment of web applications to on-premises servers or the cloud.
• Docker Containers: With the rise of containerization, .NET applications can be deployed using Docker containers, which encapsulate the application and its dependencies in a standardized unit.
• Cloud Providers: Cloud platforms like Azure, AWS, and Google Cloud provide services to host and deploy .NET applications. Azure App Service, for example, is tailored for hosting web apps, RESTful APIs, and mobile app backends.

3. Configuration Management:

• appsettings.json: In ASP.NET Core, application configurations like connection strings can be stored in the appsettings.json file and its environment-specific variants (e.g., appsettings.Production.json).
• Environment Variables: It’s better to use environment variables or secret management tools provided by cloud platforms for sensitive data like API keys.
• Secret Managers: Tools like Azure Key Vault or AWS Secrets Manager can be integrated with .NET applications to manage and access sensitive configurations securely.

4. Monitoring and Diagnostics:

• Logging: ASP.NET Core has a built-in logging infrastructure that can be integrated with various logging providers like Serilog, NLog, or cloud-specific logging services.
• Application Insights: A monitoring tool from Azure that provides telemetry data, performance metrics, and error tracking for your live web applications.
• Health Checks: ASP.NET Core provides a health check middleware that allows you to report application health.

5. Scaling and Load Balancing:

To handle increased loads or provide high availability, applications can be scaled:

• Horizontal Scaling: Involves adding more instances of the application. Load balancers then distribute incoming traffic across these instances.
• Vertical Scaling: Involves adding more resources (like memory or CPU) to the existing instance of an application.

6. Updates and Rollbacks:

• Blue-Green Deployment: Deploy the new version alongside the old version. Once the new version is tested and confirmed stable, traffic is switched to the new version, allowing for easy rollback if necessary.
• Rolling Updates: Update instances incrementally to ensure no downtime and users don’t experience interruptions.

7. Backup and Disaster Recovery:

Regularly back up application data and configurations. Plan for disaster recovery to ensure quick restoration in case of failures.

8. Continuous Integration and Continuous Deployment (CI/CD):

Tools like Jenkins, Azure DevOps, GitHub Actions, or GitLab CI can automate the build, test, and deployment processes. This ensures quick, consistent, and reliable deployments.

9. Staying Up-to-Date with .NET and the Developer Community

Finally, staying up-to-date with the latest trends, best practices, and technologies in the .NET ecosystem is essential for a successful career as a .NET developer. Some ways to stay informed include:

• Following the official .NET Blog
• Attending conferences, meetups, and webinars
• Participating in online forums and communities (Stack Overflow, Reddit, GitHub)
• Following industry leaders and influencers on social media
• Regularly reading books, articles, and tutorials on .NET topics

By following this comprehensive roadmap and staying engaged with the .NET developer community, you’ll be well-prepared to excel as a .NET developer in 2023 and beyond.
