My properties with Many relationships must use ICollection to support LazyLoading in Entity Framework 4.1?

I'm found this Mic开发者_如何学JAVArosoft Article (http://msdn.microsoft.com/en-us/library/gg715126%28v=vs.103%29.aspx) that says:

A navigation property that represents the "many" end of a relationship must return a type that implements System.Collections.Generic.ICollection of T, where T is the type of the object at the other end of the relationship.

My properties with Many relationships must use ICollection to support LazyLoading in Entity Framework 4.1?

Instead if i'm using IList, the Lazy Loading doesn't occur?

The paragraph you're quoting doesn't say anything about lazy loading and is under "For change tracking proxies", so I can't see why it should be relevant for lazy loading.

But IList implements ICollection, so it shouldn't be a problem anyway.
