Entity Framework 4, TPH (Table Per Hierarchy) and annotation

问题

I currently try to migrate an application of mine from datasets to EF4. So I have an existing database. One of the tables is mapped to 2 classes, depending of the value of a column. So I am in a TBH schema with an existing table and an existing discriminator. Is there a way to discribe this using annotations ?

thanks

No. TPH discriminator can be controlled only through Fluent-API.
