Hi,
I am very new to Windows Azure.
I have my WCF cloud service.
I created a storage account in Azure.
Now i right click and publish my cloud service.

Now it window activity log gives errror:
Your role instances have recycled a number of times during an update or upgrade operation. This indicates that the new version of your service or the configuration settings you provided when configuring the service prevent the role instances from running. Verify your code does not throw unhandled exceptions and that your configuration settings are correct and then start another update or upgrade operation.

Any Idea.Plz help!
