I realise that this has been asked a number of times but I just can\'t seem to get the bottom of my issue. I\'m getting the following error stack:
I was having the same issue
System.Data.MetadataException: Unable to load the specified metadata resource
It turned out the Connection string which was generated earlier had all the edmx's name on it. I took out all the model names from the connection string leaving only the below string in my metadata
"metadata=res://*/;provider=System.Data.SqlClient;provider
This worked for me.
