Update-Database Fails on the latest release #2717

Hi, I downloaded the latest release. I added all my changes from existing solution files + entities into the EntityFramework.

Then, I hit Update-Database, I get an exception as shown below.

The weird thing is that, the Default connection string points to localhost server and not to .\SqlExpress, how come Update-Database (While selecting .EntityFramework project) doesn't read the actual connectionstring from .Web?

Also, when I try something like this:

PM> Update-Database -Verbose -ConnectionStringName "Default"

I receive:

No connection string named 'Default' could be found in the application config file.
PM> Update-Database -Verbose

    Hi,

    I think you didn't choose web project as startup project.

    Ah, that's the main reason you think? Why is that.

    Hi,

    Because EF project does not have connection string in it's configuration and Update-Database command checks startup project's config for connection string.

    Did you manage to make it work ?

    Hi Ismail,

    Before trying your solution, I provided a -ConnectionStringName "Default" and that worked well.

    I then also tried your solution and it works.

    But why would sometimes (before configuring the Web as startup) why would EF make use of a default connection string pointing to .\SQLExpress?

    Thanks

    Hi,

    I'm not %100 sure but probably it is the connection stirng in your machine.config.
