@dongfengxin The Dictionary.cs is defined in dotnet runtime not in wpf. I think your issues has been submitted to the wrong repo. How about bring to https://github.com/dotnet/runtime/
Dictionary.cs not found
This is the message Visual Studio displays when trying to debug the ArgumentNullException to load the source file where the exception occurred, but this has nothing to do with the error you are facing here.
Just putting screenshots of the exception stack is no steps to reproduce, that way no one can say, what's the root cause of this exception. Please try to add real reproduction steps.
By the way on the first glance it looks like your ItemsSource contains a null item or something else is null but shouldn't be.
