Exceptions should be properly documented when applicable

[Youssef1313]

Seeing an exception like this doesn't give useful info:

   at WinRT.ExceptionHelpers.<ThrowExceptionForHR>g__Throw|20_0(Int32 hr)
   at ABI.Microsoft.UI.Xaml.Controls.IContentControlMethods.set_Content(IObjectReference _obj, Object value)
   at Microsoft.UI.Xaml.Controls.ContentControl.set_Content(Object value)

and the documentation doesn't mention what exceptions can be thrown from ContentControl.set_Content and when those exceptions occur.
