If you don't have nuget installed download at www.nuget.org you can find EF v5.x  When you install EF5 and EF5.X DbContext Generator you have to add Model1.edmx into Model1.tt(const string inputFile = @"Model1.edmx";) && Model1.Context.tt (const string inputFile = @"Model1.edmx";)  where the error occurs. Then you need to set property Code Generation = None in Model1.edmx this will not generate Model1.Designer.cs... Now you updated to EF5
Happy coding...:)
