Q. Why do I still need to include the same Entity connection string the the Web Project web.config which is already used in the Database project's app.config?

Makes me wonder why the Database and Edmx is in a separate project within the same solution.

It seems that referencing the Database and using the following code would eliminate the need.

[Web Project Controller]

The database project is just a library. It's configuration is not read unless you read it yourself. The runtime will automatically load the connection string from the main application's configuration file. That is where your connection strings should go for execution.

Understood, thx...

I have an unusual project request of moving both database and Models folder into a separate project. So I did and of coarse the main project failed to build. I then added Entity and Identity references to the database project. Now the main project build and runs like a normal mvc 5 web site should. Get this, I removed the connection strings from the main project web.config and it runs great. I further tested it with typical Entity/Linq CRUD and it works fantastic. So the only connection strings are in the database projects web.config. Unbelievable!

OK, then maybe this is a feature of Entity Framework--in all of the (non-EF) projects I have worked on, it is as I mentioned above.
