WPF App crashes

Very simple WPF application, if I add

to the app.config

the app crashes with

An unhandled exception of type ‘System.TypeInitializationException’ occurred in PresentationFramework.dll

Can you dig deeper into the stacktrace see exactly what is causing the TypeInitializationException? Posting the whole stacktrace is usually best.

Thank you for the reply. Looks like it was the ordering of the configuration items in the app.config. I only found this out from reading other posts with similar errors. I didn’t think this would cause a crash, but apparently so.
