WinFormsComInterop is a .NET library that provides a custom ComWrappers implementation for Windows Forms (and WebView2) to enable NativeAOT compilation and trimming. It includes a source generator that automatically produces Runtime Callable Wrappers (RCW) and COM Callable Wrappers (CCW) for arbitrary COM interfaces, reducing manual interop code. The repository also contains facade assemblies that stub out dependencies on System.Windows.Forms, WindowsBase, PresentationCore, and Microsoft.Web.WebView2.Core, allowing AOT-friendly builds without full desktop framework references. Multiple sample applications demonstrate usage with WinForms, Blazor Hybrid, hosted WinForms in native DLLs, and trimming. The project is actively maintained and targets .NET 6 through .NET 10, but relies on pre-release SDK versions and has some experimental components (WPF, WinUI) that are not production-ready.
