Question

I’ve used EF code first to create a DB. Works great in dev. I copy it to a windows server 2003 box and I get these errors (listed below)

EF 5, .NET 4.0.

I’ve uninstalled and reinstalled the .net 4 framework. as well as tested on other machines.

On my Windows Server 2008 box it works fine. On another 2003 box it does not.

To take MVC out of the equation, i built a simple console app that lists out some data from the db. – Same error there.

I had written everything in VS 2012 with .net 4.5 installed on the machine. I read that could cause an issue, so I re-wrote everything in VS 2010 targeting .net 4, and manually added the reference to the EF 5/.net4 dll. Same thing, works great on my 2 dev machines, and on the 2008 server, but not 2003.

Here’s the stack trace (It’s a MVC app)

Answer 1

I was able to fix this by changing my connection string to have ef create the db fresh with the proper dll installed on the project. I then migrated the data from the old db to the new one.

My assumption is that the EF 5 code stored some meta data in the DB (although i couldn’t verify this). Since EF code first will create the db/schema if the database doesn’t exist, I simply changed my connection string to a non-existant database, ran the project and let EF build the db, then migrated the existing data from the DB created by V.5 to the db created by v.4.
