Correct way to check for IsCursorCaptureEnabled support? about windows.ui.composition-win32-samples HOT 7 CLOSED

Shouldn't 19041 come with IsCursorCaptureEnabled support? I tried to use that in a netstandard2.0 project defining this:
PackageReference Include="Microsoft.Windows.SDK.Contracts" Version="10.0.19041.1"

ApiInformation.IsTypePresent(@"Windows.Graphics.Capture.GraphicsCaptureSession") results to TRUE but
ApiInformation.IsPropertyPresent(@"Windows.Graphics.Capture.GraphicsCaptureSession", @"IsCursorCaptureEnabled") is FALSE

Am I doing something wrong?

EDIT: Please excuse and ignore my question. I just checked whether I had the right SDK version installed which was not the case.

EDIT 2: Now that I have the right SDK installed I still see those results. Strange...

EDIT 3: gosh Windows10 just really really wasn't finished installing update 2004, so after some more restarts it now works.

I leave this comment here for anyone who might run into the same situation ;-)

if(Windows.Foundation.Metadata.ApiInformation.IsApiContractPresent("Windows.Foundation.UniversalApiContract", 10))
{
    GraphicsCaptureSession.IsCursorCaptureEnabled = value; // maybe check 
}

The way sometimes does not work in C# constructor.
Even if you set judgment, there may still be errors and errors will pop up.
It may be because C# will check all the property in advance,
so I use reflection to avoid it, AS SHOW BELOW

if (Windows.Foundation.Metadata.ApiInformation.IsApiContractPresent(
"Windows.Foundation.UniversalApiContract", 10))
{
    var aa = GraphicsCaptureSession.GetType().GetProperty("IsCursorCaptureEnabled");
    if (aa != null)
        aa.SetValue(GraphicsCaptureSession,false);
}

To check if capture is supported at all use the following (assumes Windows.Foundation.UniversalApiContract v1 is at least present):

auto supported = 
    winrt::Windows::Foundation::Metadata::ApiInformation::IsTypePresent(L"Windows.Graphics.Capture.GraphicsCaptureSession") && 
    winrt::Windows::Graphics::Capture::GraphicsCaptureSession::IsSupported();

The first part checks to see if the capture API is present at all. The second part checks whether screen capture is present (e.g. This currently returns false on the Xbox).

To check for individual feature availability, use the following:

auto supported = 
    winrt::Windows::Foundation::Metadata::ApiInformation::IsPropertyPresent(
        L"Windows.Graphics.Capture.GraphicsCaptureSession", 
        L"IsCursorCaptureEnabled");

PS: It is technically possible to use the capture API if IsSupported returns false, but only by using GraphicsCaptureItem::CreateFromVisual (your own content).

I'll use these. Thanks.

No problem!

For window capture support as a whole, I'm going back to UniversalApiContract >= 8 for the time being. GraphicsCaptureSession exists on 1809, but IGraphicsCaptureItemInterop does not, so we were falsely reporting support for that version.

Ah sorry, I should have mentioned that. We introduced the capture API before we introduced the Win32 specific interface. Since you rely on that, checking support for UniversalApiContract 8 is certainly the way to go.
