Calling System.Diagnostics.Trace from Dynamics CRM 2011 Plugin

Question

I wonder if any of you have any ideas on the next issue I am facing.

Here are some super simple plugins.

namespace Demo.DebugTraceBlog { public class TraceAndDebugDemo : IPlugin { public void Execute(IServiceProvider serviceProvider) { Trace.WriteLine("Started Plugin"); Trace.WriteLine("Plugin Working"); Trace.WriteLine("Ending Plugin"); } } } 

Im using DebugView (http://goo.gl/YRfus) to view the recorded Trace messages. When I run this code as a plug-in running in the sandbox, I get the expected results: three lines appear in the DebugView, and if I attach the VS to the Sandbox workflow, I see three lines written in the output window. Now, when I change the isolation mode to none, and let it start in the W3WP.EXE process, I don’t get any output in DebugView, and when I connect to W3WP.EXE, I can set a breakpoint to check if it works, but I don’t get any output in the output window.

Any idea on why this is happening, and how I can get around the cause and make non-sandbox execution work properly. I can guess that this is due to running within the IIS CRI processes and that CRM suppresses the trace record - I specifically used Trace instead of Debug in an attempt to avoid this problem, but no luck.

I know that I can use ITracingService, but this does not meet my current requirements.

(Guess) Add this to your configuration file. If this worked, then your problem is that the .NET trace has some problems with its default receiver when it is in a different application domain.

Change D:\Log\MyApp\Program to the path to which ASP.NET has full access.
