Use this property in conjunction with Visual Studio Options
There are settings in the Visual Studio Options dialog that can affect what trace elements are actually displayed in the Output Window. If you open the Options dialog, go to Debugging > Output Window > WPF Trace Settings, you can set the output level for each trace element (eg. Animation, Data Binding, etc.) to a value between Off and All. The full value list (in order) is Off, Critical, Error, Warning, Information, Verbose, Activity and All. Note that if all trace elements are set to Off, there will be no trace information displayed in the Output Window.
