How to change language version in Visual Studio

To change the language version in Visual Studio, you can follow these steps:

  1. Right-click on the project in the Solution Explorer and select "Properties" from the context menu.

  2. In the project properties window, select the "Build" tab.

  3. In the "General" section, you'll see a dropdown labeled "Language version". Click on this dropdown and select the version of C# you want to use.

  4. Once you've selected the desired language version, click the "Apply" button to save your changes.

Note that the available language versions may depend on the version of Visual Studio you're using, as well as the version of the .NET Framework or .NET Core SDK installed on your system. If the desired language version is not available in the dropdown, you may need to install a newer version of Visual Studio or the .NET Framework/.NET Core SDK.

Additionally, you can set the language version for individual files by adding the following line at the top of the file:

#pragma language_version(X)

Replace "X" with the version number of C# you want to use (e.g. "9.0" for C# 9.0). This will override the project-level language version setting for that particular file.
