Yep, .NET 2.0, 3.0 and 3.5 all share the same fundamental CLR and the BCL bits
are strictly additive. A simple cast is not sufficient; the code will need
modification. One approach would be to insert a 3.5-only adapter function which
does something like this:
IEnumerable<object> Convert(IEnumerable<MutableString> collection) {
foreach (var item in collection) {
yield return item;
}
}
(I'd need to refer to the context of the code to make any other suggestions.)
Is downlevel-framework support still a goal for IronRuby? I seem to recall that
IronPython 2.7 is .NET 4.0-only.

I believe that "v2Release" targets the 3.5 framework (is that the same as
CLRv2?), but someone can correct me if I am wrong.
I'm currently running a previous version of IronRuby built for "v2Release", so
perhaps there is at least a patch that we can apply (will a simple cast be
sufficient?).
I'm trying to build the latest versions of IronRuby and IronPython for
inclusion into the next version of Ubuntu. The versions built on
dlr-0.9 were just removed. However, I must admit that I don't know if people
will really need v2Releases... I just thought I'd build them if I could.
