Add Presentation.h and PresentationTypes.h (Win11 Composition Swapchain API)

[rickbrew]

This looks right except that Windows.CreatePresentationFactory has a blank DLL name: [DllImport("", ...)]. It should be dcomp.dll as per https://learn.microsoft.com/en-us/windows/win32/api/presentation/nf-presentation-createpresentationfactory

Edit: Fixed the DLL name for the [DllImport] on CreatePresentationFactory

ResolveDllImportTests is probably failing because the CI server isn't running on a build of Windows that has these APIs? A whole bunch of other APIs are failing the same test, too.

[rickbrew]

The unresolved TaskDialogIndirect is because there's neither a manifest nor an activation context that specifies to use version 6 of the DLL instead of 5.82. Normal stuff.

You should be able to get these automatic by adding the type it uses to https://github.com/terrafx/terrafx.interop.windows/blob/main/generation/remap-namespaces.rsp, which should just tell the system that DXGI_COLOR_SPACE_TYPE is in TerraFX.Interop.DirectX

You should be able to add the entries to the handler in https://github.com/terrafx/terrafx.interop.windows/blob/main/tests/Interop/Windows/ResolveDllImportTests.cs#L53

There's an existing grouping for cases that simply aren't on server, but if its instead relegated to a particular version of Windows then you can place it in a separate grouping with the relevant guard.

That is already be getting handled via https://github.com/terrafx/terrafx.interop.windows/blob/main/tests/Interop/Windows/ResolveDllImportTests.cs#L218 and warning, not erroring.

The only actual failure is CreatePresentationFactory

It should be possible to test the comctl32.dll exports without a manifest by using an activation context. Might not be worth the trouble though.

CreatePresentationFactory does indeed work :)

using static TerraFX.Interop.Windows.Windows;

unsafe void Main()

    using ComPtr<IDXGIFactory7> spDxgiFactory = default;
    HRESULT hr = DirectX.CreateDXGIFactory2(
        0,
        __uuidof<IDXGIFactory7>(),
        (void**)spDxgiFactory.GetAddressOf());

    using ComPtr<ID3D11Device> spWarpDevice = default;

        null,
