Purpose and Use Cases - (.NET Standard Tutorial)

.NET Standard is a specification for building cross-platform .NET applications. It defines a set of APIs that must be available on all .NET platforms, allowing developers to write code that can run on any platform that implements .NET Standard. In this tutorial, we'll cover the purpose and use cases of .NET Standard.


.NET Standard is not a programming language, so there is no syntax to learn. Rather, it is a specification that defines a set of APIs that must be available on all .NET platforms.


Here is an example of how .NET Standard can be used in a .NET application:

using System;

namespace MyApplication
    class Program
        static void Main(string[] args)
            Console.WriteLine("Hello World!");

This is a simple C# console application that uses .NET Standard to access the Console class and write a message to the console.


.NET Standard is designed to solve the problem of creating cross-platform .NET applications. In the past, developers had to create separate versions of their applications for each platform (e.g. Windows, Linux, macOS). This was time-consuming and made it difficult to share code between applications. With .NET Standard, developers can write code once and run it on any .NET platform that implements the .NET Standard APIs.

Use Cases

There are several use cases for .NET Standard:

  • Cross-platform development: .NET Standard enables developers to create cross-platform applications that can run on any .NET implementation. This is particularly useful for applications that need to run on multiple operating systems or devices.

  • Library development: Developers can use .NET Standard to create libraries that can be used across different .NET implementations. This makes it easier to share code between applications and reduces the duplication of effort.

  • Code reuse: .NET Standard enables developers to write code once and run it on any .NET implementation. This makes it easier to reuse code across different applications and platforms.

Important Points

Here are some important points to keep in mind when using .NET Standard:

  • Not all .NET platforms support .NET Standard. You should check with the documentation of the platform you plan to use to confirm support.

  • The version of .NET Standard that your application uses will affect which APIs are available to your code. Be sure to choose the version that best meets your needs.


In this tutorial, we discussed the purpose and use cases of .NET Standard. We covered the syntax, example, explanation, use cases, and important points of .NET Standard. With this knowledge, you can start using .NET Standard to build cross-platform .NET applications and libraries.
