That doesn't look so good! What was the exact query you were trying?

Hi,
What is the recommended way of using the new Linq provider? I'm using
the trunk version and trying to do a simple thing: fetch entities by a
foreign key.
So, I've got the Product class and it has the Category property. How
do I fetch all products given a categoryId?
.Where (p => p.Category.Id == categoryId)
or
.Where (p => p.Category == session.Load<Category>(categoryId)
?
Thanks
ulu
