Visit [.NET Documentation](https://learn.microsoft.com/dotnet/) to learn about .NET, for building many different types of applications.
27+
28+
## Visual Studio Compatibility
29+
30+
You need [Visual Studio 17.10](https://visualstudio.microsoft.com) or later to use .NET 8.0 on Windows. While not officially supported, we’ve also enabled rudimentary support for .NET 8.0 in Visual Studio for Mac. Users have to enable a preview feature in Preferences to enable the IDE to discover and use the .NET 8.0 SDK for creating, loading, building, and debugging projects. The [C# extension](https://code.visualstudio.com/docs/languages/dotnet) for [Visual Studio Code](https://code.visualstudio.com/) supports .NET 8.0 and C# 12.
