Client-Server Architecture:
HTTP Protocol:

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

Front-end and Back-end:
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:
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:

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:

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

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:

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:

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.

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.

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.

.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:

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:

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.

Live Metrics Stream: For applications running in Azure, you can view real-time telemetry data within Visual Studio.

2. .NET Profilers:

There are third-party profilers designed specifically for .NET applications:

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:

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:

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.
