There was an error attaching the debugger to the IIS worker process for url xxx for role instance deployment(xxx).ProjectName.Web_IN_0. Unable to start debugging on the web server. The web server did not respond in a timely manner. This may be because another debugger is already attached to the web server.

 

 

This error can haunt you for a hours and still you will not be able to figure why this is happening. There could be a lot of reason for this but, strangely this is the same error the Visual Studio gives when your storage account is not getting connected and you are accessing it anywhere on the global.asx. Mostly we use this for “DataConnectionString” or for “Diagnostics”. So ensure that your storage account mentioned is configured properly before you go fishing for other things.
