Main goal of extension is to resolve "StoreGeneratedPattern Property in ADO.NET Entity Model Designer sets CDSL annotation but not SSDL attribute." issue. This issue still exists in Visual Studio 2010/2012/2013, and "Service Pack 1" did not resolve it.
Extension are copying StoreGeneratedPattern value from CDSL to SSDL when user save model.
Extension based on Pablo Cejas workaround. Originl source you can find at http://cid-5f3105e7f353e37e.office.live.com/browse.aspx/Public/EF505178Workaround.
Extension was not tested with 2012/2013 VS!
