localdb

I'm trying to do the Code First Walkthrough of the entity framework ( http://blogs.msdn.com/b/adonet/archive/2011/09/28/ef-4-2-code-first-walkthrough.aspx ). I have the latest SQL Server Express and when I check my versions available via command line ( sqllocaldb info ): I see localdbApp1 and v11.0. When I try to run the walkthrough with a few minor tweaks, I get a can't connect error. My app.config looks like this: <parameter value="Server=(LocalDB)\v11.0; Integrated Security=True; MultipleActiveResultSets=True" /> I wrote a simple connection test like below and the code returns the same SQL

I'm encountering the exact issue as described here (read section "Cannot Attach to Deleted MDF File"), but the solution to the problem is not told there... In short the issue is that after deleting the .mdf file, the following exception is thrown when I try to access the DB using EF 5.0. DataException->EntityException->SqlException: Cannot attach the file ‘{0}' as database '{1}' I did delete the DB file and now I get that nasty error message when running the application expecting it to use it's initializer. Any way to fix this? CodingWithSpike If you delete the DB file, it still stays

I can't believe I couldn't find a working solution to this after an hour of searching. I'm following this article on Entity Framework 6.0 which gives a simple walk-through on Code First. I created the project and installed the latest EF Nuget package for the project to compile. I also verified that I have Microsoft SQL Server 2012 Express LocalDB installed which came with Visual Studio 2013. I don't have any other instances of SQL installed on my local computer. The program runs and entries are added to the database and outputted in the console. But when the article says "check your localdb"
