.NET 4: Native generic collection support (ISet) ?

Since .NET 4 Microsoft has closed the gap for generic Sets. So there is now native support for generic Sets available:

System.Collections.Generic.ISet

When I tried to use it, FluentNH returned a type cast exception (obviosly Iesi.Collections.ISet is still used internally). What I didn't try yet is to use IEnumerable and then use Systems.Collections.Generic.HashSet (I guess Iesi.Collections.ISet should inherit from IEnumerable...)

My question is, can we expect native generic collection support for sets in the future?

    You can use HashSet with no problems.

    As for when true support will come, that'll depend entirely on when NH supports it.

    Ok fine, thanx! But I can't expose the generic interface right (of course I could expose it seperately and avoid mapping the property)?

    You can expose a HashSet as an ICollection.

    I just tried this, but it doesn't work with automapping out-of-the-box. Obviosly I miss to implement some kind of IConvention override, but I'm nut sure which I need to override and how it should basically look like.

    As I feel this is related to this topic, here is the link for the new support platform:
