Today is the official GA release for .NET 5, and along with it we are excited to share the latest updates with our recent release of C#/WinRT version 1.0. C#/WinRT provides WinRT projection support for .NET 5 based apps. The Windows SDK leverages this technology and is now integrated with the .NET 5.0 SDK to expose Windows APIs through the new Target Framework Monikers. In addition to the Windows SDK support added for .NET 5, C#/WinRT itself allows component authors to build their own .NET 5 projections using the CsWinRT NuGet package.  

You can download and get started with .NET Core 2.2, on Windows, macOS, and Linux:

• .NET Core 2.2 SDK (includes the runtime)
• .NET Core 2.2 Runtime
