Entity Framework The underlying provider failed on Open

Question

Below is my connection string:

connectionString=\"metadata=res://*/EDMX.Test.csdl|res://*/EDMX.Test.ssdl|res://*/EDMX.Test.msl;provider=System.Data.Sq

Answer 1

I was facing the same error today, what I was doing wrong was that I was not adding Password tag in the connection string. As soon as I added the Password tag with correct password the error went away. Hope it helps someone.
