This tutorial explains how to setup remote connection to MSSQL Server 2005. You can read this tutorial here.
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...:)
