Hey there,

I work on the .NET Native team and would take a closer look. Can you mail this stack to us at dotnetnative@microsoft.com and we'll work to get a repro from you to analyze. Thanks!

Simon

@nattress Thanks Simon. Just sent you an email.

Hi,

Is there anything new about this one. I have a very similar issue and I don't have an idea.

Thanks.

I'm getting the same issue here while building a UWP project with MSBuild. Any updates?
