Problem with connectionstring and entityframework

Question

I have a database (sql 2008 mdf file), a class library project with an edmx file, created with the wizard. So the connection string is also made by the wizard. This project is on a teamfoundation server.

I can use all the wizard made objects when coding.

But when i run the program and I try to make an entityContainerName, the program crashes and gives this error:

The specified named connection is either not found in the configuration, not intended to be used with the EntityClient provider, or not valid.

on this line: public TestEntities() : base("name=TestEntities", "TestEntities")

How can I solve this problem or what am I doing wrong?

Answer 1

You need to copy the connection string from the class library's config file into the config file of the application that is actually running.

Answer 2

First: delete your model, second: delete all the connectionstrings in your app.config.

Then recreate the model. This should set everything back to default.
