+The .NET 6 SDK or Visual Studio 2019 Update 11 (16.11).
 
-In addition, some generated code may require use of the C# 9 language version (`<LangVersion>9</LangVersion>`) in your project file. See [issue #4](https://github.com/microsoft/CsWin32/issues/4) for more on this.

+In addition, some generated code may require use of the C# 9+ language version (`<LangVersion>9</LangVersion>`) in your project file. See [issue #4](https://github.com/microsoft/CsWin32/issues/4) for more on this.
