As I have announced on VC Blog, VC++ libraries team has integrated another big updated to STL/CLR. We have added two new adapters that are designed to interop with .Net Framework Collection classes and STL/CLR. Also we have fleshed out support for IDictionary/IDictionary<K,T> and KeyValuePair<K,T> to map and hash_map. And we have also fixed a bunch of customer reported bugs in addition to all issues found by our test team. Take a look on examples for new features and other details in my post on VC Blog. You should be expecting to see this version of STL/CLR in February CTP for Visual Studio Orcas.
