Commented Issue: DbConfiguration.SetInitializer Reference Context Problem [671]

I'm unable to use the SetInitializer method of EF6 DbConfiguration. Here's the problem I'm encountering.

I have one project for my model, HotelRoomsModel, which inherits DbContext.
I'm using Migrations so in the same project, I have a Configuration file.

In a second project I created a DbConfiguration class and one of the configuraitons is to set the database initializer for my model.

namespace DataLayer.DbConfigurations
{
public class CustomDbConfiguration : DbConfiguration
{
public CustomDbConfiguration()
{
SetDefaultConnectionFactory(new LocalDbConnectionFactory("v11.0"));
SetDatabaseInitializer(new MigrateDatabaseToLatestVersion
<HotelRoomsModel, HotelModel.HotelMigrations.Configuration>());
}
}
}

In order to specify the context, this project needs a reference to the model's project.

Now I need to "trigger" the configuration. One method as per your overview is to use an attribute in the DbContext. However, that would require the model project to have a reference to the DbConfiguration project which would create a circular reference.

So that's problem #1 because my understanding of the specs and the overview samples was that I should be able to do this.

The alternate suggestion is to specify the DbConfiguration in the app.config file.

<entityFramework codeConfigurationType="DataLayer.DbConfigurations.CustomDbConfiguration,DbConfigurations"/>

I have yet another project which is a console app. In the main method all I'm doing is initializing my model.

If I run without debugging, I get a stackoverflow exception.

If I debug I can see it hit the code as follows:

1) Instantiate HotelsRoomsModel class
2) Instantiate CustomDbConfiguration class
3) SetDefaultCOnnetionFactory in CustomDbConfiguraiton
4) SetDatabaseInitalizer in CustomerDbConfiguration
5) Then it seems to recursively instantiate this class over and over until it overflows.

I stopped it before it overflowed even then the inellitrace file I collected is over 16MB and too big to attach.

Can you easily reproduce it? Would you like me to attach a solution? Or am I doing something very obviously wrong that you can see in the description above?
