“Unable to retrieve the metadata for …” Error while using ASP.NET MVC 3
While adding a controller in ASP.NET MVC 3 application, you might get a error “Unable to retrieve the metadata for …”. This error is due to the incorrect connection string name or the connection string in the web.config. I had encountered the same error and the issue was that the name of my DBContext was different from that of the web.config connection string name. When I made it same it was able to create the controller.
