We could probably remove build/Install-WindowsSdkISO.ps1 and build/Install-WindowsSdk.ps1

Quick question, otherwise looks good. Did you want me to also validate on another machine? As I realized my laptop isn't on insider.

[michael-hawker]

Was this the part you said wasn't supported anymore? Should we have a comment here calling that this must be set this way and throw an exception in the else case below?

[azchohfi]

We should remove the else clause. It doesn't work. There will be a future PR with a more complex scenario covered.

[azchohfi]

Let's validate it all on Monday.

Nugets from PR worked like a charm on my Insider machine. No large hassle with your instructions, just had one extra thing to do. So, it's now:

1. Install the following

• 18226 or later OS and SDK
• .NET Core preview4
• Suggested to install VS 2019 Preview

2. File New WPF .NET Core project
3. Add Microsoft.Toolkit.Wpf.UI.XamlHost package reference
4. In project, Add -> New Item -> Application Manifest File
5. Add following to compatibility/application section:

      <maxversiontested Id="10.0.18362.0"/>
      <supportedOS Id="{8e0f7a12-bfb3-4fe8-b9a5-48fd50a15a9a}" />

6. Add following to application/windowSettings section:

      <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true/PM</dpiAware>
      <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2, PerMonitor</dpiAwareness>

7. Create a Program.cs file with:

namespace WpfCoreTestApp
{
    public static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        public static void Main()
        {
            using (var xamlApp = new Microsoft.Toolkit.Win32.UI.XamlHost.XamlApplication())
            {
                var appOwnedWindowsXamlManager = xamlApp.WindowsXamlManager;

                var app = new App();
                app.InitializeComponent();
                app.Run();
            }
        }
    }
}

8. Edit the .csproj file and add the following to a PropertyGroup:

    <ApplicationManifest>app1.manifest</ApplicationManifest>
    <StartupObject>WpfCoreTestApp.Program</StartupObject>

9. Voila! XamlHost in your XAML:

<xamlhost:WindowsXamlHost InitialTypeName="Windows.UI.Xaml.Controls.TextBox" />
