(Each correct answer presents part of the solution. Choose two.) A.    A trace listenerB.    A debug listenerC.    Debug.Asset() statementsD.    Debug.WriteLine() statementsE.    Trace.WriteLine() statements Answer: BCExplanation:Tracing is a way for you to monitor the execution of your application while it is running.Example:For example, suppose you set up two listeners: a TextWriterTraceListener and an EventLogTraceListener. Each listener receives the same message. The TextWriterTraceListener would direct its output to a stream, and the EventLogTraceListener would direct its output to an event log. The following example shows how to send output to the Listeners collection.C#VB// Use this example when debugging.System.Diagnostics.Debug.WriteLine("Error in Widget 42");// Use this example when tracing.System.Diagnostics.Trace.WriteLine("Error in Widget 42"); Braindump2go Latest 70-516 Exam Dumps Released! 100% Real Questions - Dumps Qulification is the secret of Success!
