I added an Issue tracker item on .Net Micro Framework codeplex site.

If it gets some attention from others they may concider it. The new .Net 4.5 “async” and “await” keywords (see c9) allow compiler based async to allow calling async methods but look like syncronous calls which cleans up all those inversion of control issues and rats nest of nested callbacks. I think all they need a non-generic version of the support library to support what the compiler outputs. And am guessing they could bare it down to ~30K. Having this robots or non trivial sensor devices would be great. So if interested, please add support with a comment.
