Update on Persistent Iterators

Some time ago I wrote about implementing workflow with persistent iterators. This is just a reminder (in case you missed it in the comments on the original post) that Microsoft are going to change the implementation details. Until they announce details of the change, we can't be sure whether the technique I posted will work in future versions of C#.

Mads Torgersen, the C# Language PM, wrote:

We are likely to in fact change the way iterators are implemented in future versions. That said, we might be able to implement a serialization format that would work across such future changes. I agree with you that this would be a very useful feature.

If you want to use this technique in future versions, head over to this page and vote for it.
