    Posted: 21-Sep-2011 at 2:51am
I'm trying to store a single new entity which I create with the following code:

var systemUser = mgr.CreateEntity<SYSTEM_USER>();
systemUser.EntityAspect.AddToManager();
systemUser.syspasswordhash = vsPasswordHash;
systemUser.sysuser = psUsername;
systemUser.sysdomain = psDomain;
mgr.SaveChanges();

This gives me the following exception (when SaveChanges is invoked)

[IdeaBlade.EntityModel.EntityManagerSaveException] {"Key 'FortressManager': Error in DbKey EntityManager:  No CodeFirst entities were found in assembly model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"} IdeaBlade.EntityModel.EntityManagerSaveException


Maybe someone can help me here, because I did not use any code first functionality (just generated the model from the database).

Hi Engo,

It looks like you are missing the connectionString in your App.config/Web.config file.

Sorry the error message is not very clear. The message will be more informational on DevForce 6.1.3.

Regards,
   Silvio.

Thanks for your answer. The problem was that I renamed the connection string but did not copy that renamed value into the server config.

Hello, I am receiving the same error message.
My connection string is properly set.   I had generated the model from an existing database so I was surprised to see a need for CodeFirst. Here is my stack trace.  I see it coming from CreateDbContext().  Is there possibly something I need to add to my model?

Hi Louis,
 
There's nothing you need to add, but for some reason DevForce thinks your model is a Code First one, and is following that path.  Can you double check that the connection string or edmKey "EnvisionShellEntities" is in your server's config file, and that the contents of the string contain the usual "metadata=..."?

Thanks Kim

In case I didn't mention it explicitly before, I was getting this error through a unit test. 
 
After I created a small console test app (with the proper connection set in the app.config) and called the same method .. the query finally works.

I will refactor the unit test to set the connection there.

Thanks

In a unit test, be sure the app.config is deployed.  The debug log will tell you if it found the config or is using a "fall back".
