Entity Framework error - “The EntityContainer name must be unique”

Question

We have a solution which consists of two projects - a console application project and a web application project. Each of these has an identical in schema, but differently named

Answer 1

I fixed this issue in EntityFramework 6.0 by.

1. During creation of the models, I name the .edmx to the name of the entities. i.e. (MYDbEntities)

2. After creation i open the MYDbEntities.Context.cs and modified the "Entities" Class to "MYDbEntities".

3. Open the App.Config and look for the connection string
4. Open the MYDbEntities.Context.cs and change the connection string to Connection string from the config. example "MyDbConnection"

5. Make sure that the connection string is like this

   metadata=res:///MYDbEntities.csdl|res:///MYDbEntities.ssdl|res://*/MYDbEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=.;initial catalog=YourDb;persist security info=True;user id=sa;password=Sw0rdf!sh;multipleactiveresultsets=True;application name=EntityFramework"

Note: my entities resides in a separate DLL.

Hope this helps.
