Hi Alex.

That's right but there is a restriction. OrderLine columns, else than OrderId and ProdcutId which are keys, must allow null (of course). Else, you can't do it. I thought to use a default value but it I don't think it's possible on an association.

So the only way to do it is to change OrderLine ssdl, say that all columns (except keys) allow null and to use a ssdl function (stored procedure or a SQL function defined in ssdl part). With this, you can use a default value or use more interesting calculation. For example, imagine that you have a column quantity which doesn't allow null in your DB, you can count how many you have and add one on INSERT function.

I try to do it with partial extension of entity types. I blog about it. My post is in French but what do you think of the code? Can I get the context without using reflection ?
