Disable Database Initialization for Entity Framework 4.3

I'm using EF 4.3.1 and I have 100+ contexts which drives 1 base context. For all contexts I want to disable Database Initialization.

Is it possible to set default behavior for Entity Framework?

Thanks in advance

//Gather all the DbContexts types in the assembly
var allDbContextsTypes = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.BaseType == (typeof(DbContext))).ToList();

foreach (Type dbContextType in allDbContextsTypes)
{
    //Get the SetInitializerMethod
    MethodInfo initializerMethod = typeof(Database).GetMethod("SetInitializer");

    //Make it generic! (Oh yeah)
    MethodInfo dbContextInitializerMethod = initializerMethod.MakeGenericMethod(dbContextType);

    //Invoke the method with null initializer
    dbContextInitializerMethod.Invoke(null, new object[]{null});
}

In the end, it gives something like : Database.SetInitializer<YourDbContext>(null); where YourDbContext is the current dbContext type in your loop

You can change your *.config file to disable database initialization. This is done per context, but maybe it will work for your base context.

<contexts>
  <context type=" Blogging.BlogContext, MyAssembly" disableDatabaseInitialization="true" />
</contexts>

A much better explanation is given in EF 4.3 Configuration File Settings

Database.SetInitializer<TContext> is what you are after. Also passing null to this method should disable initialization.
