Unable to acess ComputeSharp.D2D1.WinUI namespace

[ReneeGA2020]

Description (optional)

I was trying to follow this doc to create a custom effect:
https://learn.microsoft.com/en-us/windows/apps/develop/win2d/custom-effects

Reproduction Steps

I added those references

  <ItemGroup>
    <PackageReference Include="ComputeSharp" Version="3.2.0" />
    <PackageReference Include="ComputeSharp.D2D1" Version="3.2.0" />
    <PackageReference Include="ComputeSharp.D2D1.WinUI" Version="3.2.0" />
    <PackageReference Include="Microsoft.Graphics.Win2D" Version="1.3.2" />
    <PackageReference Include="Microsoft.Windows.SDK.BuildTools" Version="10.0.26100.6584" />
    <PackageReference Include="Microsoft.WindowsAppSDK" Version="1.8.250916003" />
  </ItemGroup>

And successfuly finished some of the steps including creating a NoiseShader.

The next step, the doc asks me to create a FrostedGlassEffect class, and I've not been able to do that.
It looks like I cannot access to ComputeSharp.D2D1.WinUI name space even if I have ComputeSharp.D2D1.WinUI package referenced. I the CanvasEffect class is unreachable for me, and I cannot finish the step to create the FrostedGlassEffect class

System info

This section should contain useful info such as:

• ComputeSharp NuGet version 3.2.0
• Visual Studio version: 2026
• .NET Version: 10 rc1

Wait... I was using windows10.0.19041.0 when the project was created.

Changing the TargetFramework to net8.0-windows10.0.22621.0 seems work. And now I can see the namespace in the class view.

But it did't prevent me to install the "ComputeSharp.D2D1.WinUI" package when I was using 19041. Is that right?

Also SetAndInvalidateEffectGraph() in that doc seems to be obsolete. perhaps the custom effects doc was not update to date after all.
