How to extract the "WinRT Information" from a WinRTError object?

Question

the VS debugger seems to be able to extract that information from a WinRTError object:

"WinRT Information: The clipboard could not be accessed because the application is not in the foreground."

Yet, all I can extract from the WinRTError object in its message property is "Access is denied".

Answer 1

It seems the WinRTError is a java object that is not projected back to Platform::Object when I want to hand it over to a WinRT component. How can that be?
