connectionStrings for Context now needs providerName key

I get a run-time error if I don't specify providerName = "System.Data.SqlClient" in the connectionStrings for Context. This was not specified in the video.

<connectionStrings>
    <add name="Context" providerName="System.Data.SqlClient" connectionString="Data Source=(localdb)\MSSQLLocalDB;Initial Catalog=myDatabase;Integrated Security=True;MultipleActiveResultSets=True"/>
</connectionStrings>

David,

The video shows adding the providerName attribute (see https://teamtreehouse.com/library/changing-the-database-name?t=350). Are you suggesting that the video should have made it clear that you'd get an exception if you don't provide that attribute?

Thanks ~James

Thanks James ...

What must've happened was that I used the video slider controls to get to spot in the video to see the 1st line of the connectionStrings, but didn't go further to see where you added the providerName in the 2nd line.

So, that's why I got the error, since the 1st line was incomplete, and that's all I originally provided.

Thanks!
