Answer 1

You must edit the .csproj file (for C#, .vcxproj for C++)

thern inside PropertyGroup :

 <PropertyGroup>
    <OutputType>WinExe</OutputType>
    <TargetFramework>net5.0-windows10.0.19041.0</TargetFramework>
    <TargetPlatformMinVersion>10.0.17763.0</TargetPlatformMinVersion>
    <RootNamespace>CSharp_WindowsAppSDK_Test3</RootNamespace>
    <ApplicationManifest>app.manifest</ApplicationManifest>
    <Platforms>x86;x64;arm64</Platforms>
    <RuntimeIdentifiers>win10-x86;win10-x64;win10-arm64</RuntimeIdentifiers>
    <PublishProfile>win10-$(Platform).pubxml</PublishProfile>
    <UseWinUI>true</UseWinUI>
    <EnablePreviewMsixTooling>true</EnablePreviewMsixTooling>
    <WindowsPackageType>None</WindowsPackageType>
  </PropertyGroup>

I think the only way to use the DESINER with WINUI3 or WINUI3 with the DESINER is: to open two instances of VS Community Edition. In one, you will run UWP version of you project, and in another, you will run WinUI3 version. After setting up interface for UWP version you can share it with WinUI3, thanks to windows organizing in win10/win11.....
