WPF sample?

[jordi-z80]

Hi, is there a working sample using KNI embedded in WPF (net core)?

I'm trying to use something like https://github.com/damian-666/monogame-framework-wpfinterop It uses reflection in D3D11Host.cs to access some MonoGame internals (_d3dContext, ...) but as on KNI those variables are on different places, it just crashes.

I've located the _d3dContext and I've been able to get some internals through reflection (strategy, context) to get to _d3dContext, but I get lost in the middle because I'm not familiar with KNI's structure.

Thanks!

stupid me... I just found that you don't need to juggle as with MG to get the device context :)

This does the trick for the d3d context

private static DeviceContext GetSharpDxDeviceContextWithReflection(GraphicsDevice graphicsDevice)
{
    D3D11.Device dev = (D3D11.Device)graphicsDevice.GetD3D11Device ();
    DeviceContext ctx = dev.ImmediateContext;
    return ctx;
}

And this for the texture

private static Resource GetSharpDXResourceWithReflection(Texture renderTarget2D)
{
    return (Resource)renderTarget2D.GetD3D11Resource ();
}

There's another function for a multisampled texture but I can pass without it for the moment :)

Hello @jordi-z80

I see you found the DX extensions.

FYI, I have a library for embedding KNI in WPF apps.
Here is a the sample https://github.com/nkast/ProtonType.Aether/tree/main/Samples/WpfInterop
The library is in the same repo.

Thanks, the version I'm using has some annoying flickering when resizing that I'm not able to find, I'll try the library as soon as I can :)
