Hi Mahesh,
Did you add the .wgx extension to the Application Extension Mapping which is on the IIS Virtual Directory you deploy to?
You should right click the Virtual Directory in the IIS manager (mmc) or even the Web Site then, from the Directory tab you should press the "Configuration" button and go to, then press "Add" button to add a new app extension mapping.
The executable should be that same as aspx, i.e. "C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll" in .NET 2.0.
The extension should be "*.wgx", choose "All Verbs" and unmark the”Check that file exists" check-box (since wgx files don’t really exist).
I hope this will do the job
