Beginners to .NET will definitely have a series of questions, such as (the following are my own questions):

1) What is the .NET framework and what does it contain?

　2) What is an assembly and how does it run in the CLR (Common Language Runtime)?

　3) C# and VB.NET both belong to the .NET platform. What are the fundamental connections and differences between them? Why can their assemblies call each other (if a new .NET-oriented language is created) , what to follow)?

If you want to understand the above issues, you need to understand the concepts of CIL (Common Intermediate Language), CLR (Common Language Runtime), CTS (Common Type System), CLS (Common Language Specification), etc., as follows It’s a simple summary I made after reading some other people’s articles.

First of all, let’s understand the concepts of .NET platform and .NET Framework (Framework) in a popular way

“Platform” (here refers to the software technology platform, and the following refers to this) means that it can run independently It exists independently and provides the environment that the upper-layer systems and applications it supports rely on for their operation. To extract it, the platform is an environment. As long as applications comply with the platform specifications, they can be run on it.

My popular understanding is that the .NET platform is an intermediary between .NET applications and the operating system. First, it provides an environment for .NET applications to run. Secondly, it plays a role between .NET applications and the operating system. The function of "decoupling" makes the upper-layer applications of the platform independent of the operating system (machine instruction set). As for how to decouple, it depends on its compilation process, which will be explained below.

A framework is like a semi-finished product of a certain application. It is a set of reusable components developed by predecessors based on their experience. It is available for you to choose and add to it to complete your own system. The idea is somewhat similar to design patterns. Frameworks are code reuse, and design patterns are design reuse. The framework is like a set of specifications provided, which regulates the development and deployment of application systems. The well-known J2EE framework defines 13 specifications.

Roughly speaking, a .NET application is an application running on the .NET Framework. Alternatively, a .NET application is an application written using the .NET Framework class library and running on the Common Language Runtime (CLR).

C# and .NET: Understanding the Relationship Between the TwoApr 17, 2025 am 12:07 AM

The relationship between C# and .NET is inseparable, but they are not the same thing. C# is a programming language, while .NET is a development platform. C# is used to write code, compile into .NET's intermediate language (IL), and executed by the .NET runtime (CLR).

The Continued Relevance of C# .NET: A Look at Current UsageApr 16, 2025 am 12:07 AM

C#.NET is still important because it provides powerful tools and libraries that support multiple application development. 1) C# combines .NET framework to make development efficient and convenient. 2) C#'s type safety and garbage collection mechanism enhance its advantages. 3) .NET provides a cross-platform running environment and rich APIs, improving development flexibility.

C# Code within .NET: Exploring the Programming ProcessApr 12, 2025 am 12:02 AM

The programming process of C# in .NET includes the following steps: 1) writing C# code, 2) compiling into an intermediate language (IL), and 3) executing by the .NET runtime (CLR). The advantages of C# in .NET are its modern syntax, powerful type system and tight integration with the .NET framework, suitable for various development scenarios from desktop applications to web services.

C# .NET: Exploring Core Concepts and Programming FundamentalsApr 10, 2025 am 09:32 AM

C# is a modern, object-oriented programming language developed by Microsoft and as part of the .NET framework. 1.C# supports object-oriented programming (OOP), including encapsulation, inheritance and polymorphism. 2. Asynchronous programming in C# is implemented through async and await keywords to improve application responsiveness. 3. Use LINQ to process data collections concisely. 4. Common errors include null reference exceptions and index out-of-range exceptions. Debugging skills include using a debugger and exception handling. 5. Performance optimization includes using StringBuilder and avoiding unnecessary packing and unboxing.

Testing C# .NET Applications: Unit, Integration, and End-to-End TestingApr 09, 2025 am 12:04 AM

Testing strategies for C#.NET applications include unit testing, integration testing, and end-to-end testing. 1. Unit testing ensures that the minimum unit of the code works independently, using the MSTest, NUnit or xUnit framework. 2. Integrated tests verify the functions of multiple units combined, commonly used simulated data and external services. 3. End-to-end testing simulates the user's complete operation process, and Selenium is usually used for automated testing.
