ConnectionString always points to SQLEXPRESS?

Jan 14, 2011 at 4:40 PM

For some reason, no matter what I change to the ConnectionString, it always point to the default SQLEXPRESS instance. I've tried to Find All and removed anything with SQLEXPRESS, yet, every time I run the solution (CodeFirst), it kept pointing to SQLEXPRESS? Any idea why? I'm using VS 2010 WD Express version so there are some solution item that I couldn't open, perhaps that's the problem?

Just some more info, even if I remove the connection string completely, it still points to the SQLEXPRESS instance with the MvcOpenId database.

The connection string that's in the web.config is actually just for the EF4 (no Code-First). Apparently I forgot to remove it while making the EFCodeFirst branch. I'll fix that when I get the chance.

I'm not sure how Code-First chooses the database, but I do know that SQLEXPRESS is the default DB it looks at. I didn't yet experiment with other databases, but I imagine you have to add a connection string with UserContext as it's name. But the database name for CF is defined in UserContext.cs:


public UserContext()
    : base("MvcOpenID")
{ }


I imagine this wouldn't override the ConnectionString database name though. These are you guesses at this point which I need to test out.

In the meanwhile take a look at the "Mapping to an existing database" section of this article:


Hope I helped,

I'm not sure what was the problem :) What I did was to copy the code to a new project and it's working nicely!

Thank you.

I'm glad it works. I will check this out when I get the chance, but at the moment I'm swamped with some other work.
