To debug change your StartAction to: C:\Program Files\Dynamo\Dynamo Revit\1.0\DynamoSandbox.exe. The project has post build actions set to:

xcopy /Y "$(TargetDir)*.*" "$(AppData)\Dynamo\Dynamo Core\1.3\packages\$(ProjectName)\bin\"
xcopy /Y "$(ProjectDir)pkg.json" "$(AppData)\Dynamo\Dynamo Core\1.3\packages\$(ProjectName)"

Change accordingly if using another version of Dynamo.
