  1. CsWin32 usage sample 

    This is a draft to drive the conversation around utilizing CsWin32 in WPF. In it I've converted SplashScreen to use CsWin32 and directly utilize WIC pointers.

This is informed by WinForms transition and utilizes some of the code, notably ComScope and IID. There is more support code that WinForms uses that eases handling of COM situations, including providing ComWrapper based "CCWs" for managed classes.

WinForms also contains other patterns for scoping handles, handling GC keep-alive scenarios, and managing agiile COM pointers and VARIANT interop.

As CsWin32 types Win32 typedefs (such as HWND, and HRESULT) it can get very awkward to exchange these if you use CsWin32 directly in multiple assemblies in the assembly graph. As such I created a new shared assembly for the interop code.

I added a batch file to simplify Visual Studio in the right context (copied from WinForms).

Choices here were expedient and made with the goal of illustrating how to do this. I have not tested anything outside of ensuring compilation works.

  2. Got the required CsWin32 dependency mirrored so the additional source…
