Entity framework CTP5 Model compatibility cannot be checked because the database does not contain model metadata

Question

I am trying to test the Entity Framework CTP 5 Code First with an existing table.

1. I defined the model class and DbContext and ran the application. It created the database and table.
2. I dropped EdmMetadata table from the database.
3. Added Trusted_Connection=true;Persist Security Info=True in my connection string.
4. When I run the application again, it gives me this error.

System.NotSupportedException was unhandled by user code

Message=Model compatibility cannot be checked because the database does not 
contain model metadata.

Source=EntityFramework

How can I make this application run without EdmMetadata table?

Answer 1

If you don't want to use EdmMetadata table try to add this into your DbContext derived class:

protected override void OnModelCreating(ModelBuilder modelBuilder) 
{
    modelBuilder.Conventions.Remove<IncludeMetadataConvention>();
}
