[j-fuxa]

CoreRT Native Build for C# WPF Aplication .NetCore 3.0 isn't propertly working:

dotnet new wpf dotnet new nuget // Add the nuget References to nuget.config dotnet add package Microsoft.DotNet.ILCompiler -v 1.0.0-alpha-* dotnet publish -r win-x64 -c release

Build Output:

See #6940

Thanks, i already see that, but in the version that i'am using "1.0.0-alpha-28406-02" + NetCore 3.0 + Win 10-x64 perfectly works for Windows Forms. But not for WPF.

WPF relies on COM heavily. COM is not supported by CoreRT yet (tracked in #4219).

I tried how far along I can get with an empty WPF application, but text input services, UI automation, etc. are used right in the startup path. They're all based on COM. An empty window will show, but the app crashes right after.
