Not running in a hosted service or the Development Fabric

Runtime Exception:
Could not create Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=2.4.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35.

{"Not running in a hosted service or the Development Fabric."}

Fix:
I accidentally had set the Web Role project as the startup project. Setting the cloud service project in the solution as the Startup project helped me get past this exception.
