Answer 1

I had the same error.

I was missing a reference to Microsoft.WindowsAzure.Diagnostics

Answer 2

Ok So even I had this exception being thrown continuously. However, my case was a little different.

I wanted to get rid of this reference as it was no longer required in the project. So I removed it from the references. But while running the application, I started getting this exception at a Debug.WriteLine(...); statement which suggested that the reference was required.

On further analysis, I found that the below section was present in the project's app.config file which was the cause of the exception.

<trace>
      <listeners>
        <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=2.8.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">
          <filter type="" />
        </add>
      </listeners>
    </trace>

After removing the reference AND also removing the above section from config file, the issue got fixed.

Hope this helps!
