I came across this blog post about a strongly typed include for EF.

That has been a sore point for me with Entity Framework.

If you have an object (Orders) and you always want to load all the children (OrderDetails) you have to do a really ugly .Include("OrderDetails"smile string! What happens if you misspell it? You get a lovely RUNTIME exception. I find it hard to believe MS missed this one. I hope it is fixed in the next EF release.

I have not tried the code in the post to see if it works. But it would be nice.

These strings are also a problem during refactoring. I've run into it with another vendors OPF believe it or not. I suppose if I didn't refactor so much it wouldn't be a problem. But I always seem to come up with "better" names as I go so I pretty much dropped it. A refactoring tool is a lot less productive when you still have to run a find in all files command after the refactoring to figure out where all those loose strings you missed are...

Yea, why didn't the EF code generator put constants in the namespace. That would let you do an include with .Table.Includes( Othertable.Name ) and it would always be the correct string. I guess you could do it yourself with extension methods.
