A tool to generate .NET AOT-friendly Win32 interop code from Microsoft.Windows.SDK.Win32Metadata or any .winmd package "related" to it.

Examples of this:

• DirectNAot which is an AOT-friendly version of DirectN : interop Code for .NET Framework, .NET Core and .NET 5+ : DXGI, WIC, DirectX 9 to 12, Direct2D, Direct Write, Direct Composition, Media Foundation, WASAPI, CodecAPI, GDI, Spatial Audio, DVD, Windows Media Player, UWP DXInterop, WinUI3, etc)
• WebView2Aot which is an AOT-compatible bindings dll for WebView2 independent from WinForms or WPF.
• ShellN interop code for the Windows Shell (IShellItem, etc.). Ships with ShellBat a .NET AOT one-exe file modern Windows file explorer with file viewers, multi-instance workflows, terminal integration, search capabilities, and deep Windows Shell interoperability.

The key points that drive how code is generated and built:

• modern code exclusively based on .NET 8+ newer source-generated LibraryImport, source-generated ComWrappers, etc. Note the result is the a .dll size is significantly bigger than what it was before.
• unsafe usage is limited.
• raw pointers usage is not exposed (we don't want to code in C# like it's another C/C++), only interface types, object types, or nint depending on the situation.
• doing interop is inherently unsafe but we want to keep a.NET-like programming whenever possible. The generated code serves a similar purpose to the CsWin32 project, but the generated code and how we program it are quite different.
