尝试使用 SharpDX 和 DXD11 在 Windows App SDK C# 中获取对 SwapChainPanel 的本机 COM 对象的引用时出现异常

Question

我正在尝试使用 SharpDX 获取对在 Windows App SDK C# 中创建的 SwapChainPanel 的本机 COM 对象的引用。

我将我的项目从 UWP 迁移到更新的 Windows App SDK with WinUI 3 and .Net 6 并且除了创建 SwapChainPael 之外一切正常。

UWP： https://github.com/CanTalat-Yakan/UWP-GameEngineEditor/blob/main/Editor/Views/View_Port.xaml.cs https://github.com/CanTalat-Yakan/UWP-GameEngineEditor/blob/main/Editor/Assets/Engine/Utilities/Engine_Renderer.cs

新Windows 应用程序 SDK： https://github.com/CanTalat-Yakan/3D_Engine-WinUI3/blob/main/WinUI3DEngine/WinUI3DEngine/WinUI3DEngine/UserControls/ViewPort.xaml.cs https://github.com/CanTalat-Yakan/3D_Engine-WinUI3/blob/main/WinUI3DEngine/WinUI3DEngine/WinUI3DEngine/Assets/Engine/Utilities/CRenderer.cs

出现上述错误的部分是CRenderer:71(ctor)

        // Obtain a reference to the native COM object of the SwapChainPanel.
        using (var nativeObject = ComObject.As<DXGI.ISwapChainPanelNative2>(m_SwapChainPanel))
            nativeObject.SwapChain = m_SwapChain;

异常详情：

我尝试从过程开始调试，一切都与 UWP 版本相似。使用新的 Windows App SDK，Windows.UI.Xaml.Controls 的命名空间更改为 Microsoft.UI.Xaml.Controls 我不太了解 SharpDX 包装器，但这可能是问题所在吗？也许 SharpDX 根本不支持 .Net 5 或 6 只有 4 及以下？我是否需要以不同方式设置 Device -Contex 和最后 SwapchainPanel 的创建？

如果我得到解决方案，如果是我的错误或其他错误，我会在下面post他们

基本上

windows.ui.xaml.media.dxinterop::ISwapChainPanelNative 与 UWP Windows.UI.Xaml.Controls.SwapChainPanel 控件一起工作

不适用于

WinUI3 Microsoft.UI.Xaml.Controls.SwapChainPanel 控件，它实现了一个不同的界面，该界面具有相同的名称但具有新的 GUID (63aad0b8-7c24-40ff-85a8-640d944cc325) 和命名空间：microsoft.ui.xaml.media.dxinterop::ISwapChainPanelNative

注意 Windows 与 Microsoft 的命名空间差异 https://githubhot.com/repo/amerkoleci/Vortice.Windows/issues/91

这里有一个解决方法： https://github.com/amerkoleci/Vortice.Windows/discussions/164

但是由于 SharpDX 被破坏，我切换到更新的包装器 Vortice https://github.com/amerkoleci/Vortice.Windows https://github.com/amerkoleci/Vortice.Windows/tree/main/src

支持WinUI 3和新的WindowsApp SDK（新项目重聚）
