Beyond HelloWorld - native exception an macOS while trying to make Photino work with 'real' Blazor application

[ChristianWeyer]

Hey all,

thanks for starting Photino :-)

I am trying to evaluate the current version and went to host one of my Blazor sample applications in Photino.Blazor. You can find it here: https://github.com/thinktecture/ttconftool-blazor

When running the app, I get this exception (in VSfor Mac):
