CRM Plug-in Trace Log - logs only for sandbox mode

Question

I have this very simple plugin

 public class TestPlugin : IPlugin
  {
    public void Execute(IServiceProvider serviceProvider)
    {
      ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
      tracingService.Trace("HelloWorld");
    }
  }

but the log is tracked only when the plugin is registered in Sandbox . When I select None , there is not any log from the plugin. I've already found some threads about this problem, but no solution. Thanks for any help.

Answer 1

You might have seen this community thread , many users are affected by this behavior. That may be the intended behavior by Microsoft .

See the comments from code sample :

//Extract the tracing service for use in debugging sandboxed plug-ins.
ITracingService tracingService =
    (ITracingService)serviceProvider.GetService(typeof(ITracingService));

But interestingly MS documentation conflicts with that .

Tracing is supported for sandboxed (partial trust) and full trust registered custom code and during synchronous or asynchronous execution.

Probably this idea will make the change, vote for it.

Answer 2

Do you get a trace log when you register in None mode and there is an error? I have, sadly, had to throw Exceptions in my plugin code before to get a log file generated to see what is going on.

Not sure if that helps.
