How to perform something similar to http://www.insidercoding.com/post/2010/ ... tance.aspx?

Here my scenario:

- I have a provider model were I have a base class Provider (contains all common properties). Maps to one table on the Db;

- Then I have 4 providers: Domains, Payments, Dns and Certificates. Earch maps to one table with the particular properties for each context;

I've tried several ways, also reading the supplied article, and I can't get the model to validate properly.

Is it possible to do this?

I'll send you a sample project in a letter, please check that it was not blocked by your mail filter.

The mentioned walkthrough apparently misses the last point: since the base type is abstract, and the derived types have no key fields, it is necessary to set mapping for the ProductId column of the Product table in each of the derived entity classes.

Please tell us if this helps.

Hi have the email. I'm going to do some tests.
