A tool to generate .NET AOT-friendly Win32 interop code from Microsoft.Windows.SDK.Win32Metadata or any .winmd package "related" to it.
An example of this is DirectNAot which is an AOT-friendly version of DirectN.
Another example is WebView2Aot which is an AOT-compatible bindings dll for WebView2.
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,
objecttypes, ornintdepending 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.
