Hi I have a setup where I used Linq2SQL inheritance. To make queries easier, I expose the derived types in the DataContext as well, like the following: public IQueryable<Derived> Derivations { get { return Bases.OfType<Derived>(); } // filter list on type } Calling this works perfectly, and I can see the SQL being correctly genera...

I'm wondering if there is something out there which I could use in a commercial application. If not, any suggestions on how to roll my own (i.e., how to look at the machines data source list)? Also...
