Below is my connection string:
connectionString=\"metadata=res://*/EDMX.Test.csdl|res://*/EDMX.Test.ssdl|res://*/EDMX.Test.msl;provider=System.Data.Sq
In my case, I resolved the error by adding connection password in the connection string.
While setting up the EF model, I had selected the option to exclude sensitive data from connection string. So, the password was not included initially.
