Windows Azure no endpoint listening at net.pipe

While running a "Hello World" applicaition i am getting following error:

There was no endpoint listening at net.pipe://localhost/dfagent/1/host that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details

To resolve above error Goto Start –> Program –> Windows Azure SDK v1.2 –> and press Development Fabric

Once Development Fabric started you can let’s start the application in debug mode or just press the familiar F5 button.
