In the latest MEF preview I noted new element called CompositionScopeDefinition. What is purpose of it and how it actually works?

I'm also curious how this is supposed to be used, as I've seen the class in .Net Framework 4.5 also.

And coincidentally I'm doing something with Scoped CompositionContainers, which is not a pretty sight in 4.0

I want to second that request. I was playing around an hour in the sources today and I just can not come to a conclusion how that is supposed to work. Would be nice to have some documentation - even the 4.5 preview documentation has nothing (I was able to find - maybe a link would be enough?).

Good questions. We're aware that documentation on this feature is very light - please bear with us while we address this.

Please. Like quite many (using MEF) I have rolled my own scoping approach that I am eager to start retiring in some projects ;) Too bad 4.5 officially is still that long away.... ;)
