Event Type



IsBindingTracingEnabled must be true and there must be a debugger attached to the app process in order for BindingFailed to fire and for tracing to appear in debugger output. You don't need to handle the event in order to see tracing appear in a debugger. The debugger output contains message information that goes to the Output window of the debugger. Attaching a BindingFailed handler yourself is an advanced scenario for when you want to see the raw message.
