README: C#/Win32 Interop Projection

C#/Win32 provides P/Invoke and COM Interop projection support for C#. It generates strongly-typed, source-generated bindings from CsWn32-compatible .winmd metadata files. CsWin32 supports the metadata of Microsoft.Windows.SDK.Win32Metadata as the 1st-party metadata.

Generates interop code quickly at compilation time.
Generates friendly overloads/extensions (including SafeHandle-types support).
Generates xml documentation based on and links back to learn.microsoft.com
Ships no bulky assemblies alongside your application.
