Open AIT-Employee opened 4 years ago

AIT-Employee commented 4 years ago

The following XAML causes a runtime exception

@AIT-Employee which version are you using?

AIT-Employee commented 4 years ago

Hello,

Thank you for answering so quickly!

The error occurred in the version available via NuGet yesterday (sorry I did’nt remember exactly, but it started with 3.5). Today it is the version 3.5.1.3. Now I use the .Net Framework version instead (V3.8.1) and there it works (but I get warnings from Visual Studio). The same XAML code worked also years ago in another application.

Sorry, I didn’t have time to localize precisely at which statement the exception occurred. I hope the information given in the issue is sufficient.

Thank you again, Thomas
