Microsoft C# Version History

The C# programming language was first released by Microsoft in 2002 along with the new .NET Framework 1.0 and Visual Studio.NET 2002. Currently, it stands as the seventh most used programming language in the world. (source: StackOverflow 2019 survey ). In this blog post, we will look into the released C# version history from its initial release version and list down the features and enhancements that have been added over subsequent releases.

Over the period Microsoft has added a ton of features to make the C# programming language a real general-purpose language using which the developer can build applications like a simple console application, desktop application, Web application, service application, and even new generation Internet of Things (IoT) applications and many more.

All of the above features have enhanced the C# programming language to a great extent and made it very easy for the developer to write cleaner code. Microsoft with the introduction of the .NET Core has made it possible to use the C# language without worrying about the platform the application will execute in. Applications of different types can be created that can work without issue on a variety of platforms like Linux, macOS, and various devices.

The Microsoft C# Language Design Team (LDT) designs the language and accepts proposals for the language. If you have a great idea about the language or want to take a look at what the LDT team is working on, you can check the “C# Language Proposals” present on the GitHub page.
