Sharepoint 2010 and Workflows: what about .NET 4.0?

As you already know, Microsoft has finally released a public beta of Sharepoint 2010 and Office 2010 (available from here).

Starting from this Beta 1, we’re working hard on Sharepoint 2010 and I want to write this post not for celebrate the big amount of interesting new features of the platform but to signal an important lack (or at least I think so).

Sharepoint 2010 actually doesn’t support .NET 4.0, it runs in .NET 3.5 SP1. I think that the main reason for this choice was due to the fact that actually .NET 4.0 is still not RTM'd (so not ready to be the core of the new Sharepoint engine), but I really hope that Microsoft is thinking to release as soon as possible a product update (maybe a SP1?) in order to give the .NET 4.0 support.

This is extremely important mainly for the workflow engine. Sharepoint workflows are based on WF 3.5, so we don’t have all the advantages of the new WF 4.0 engine (Windows Workflow was totally rewritten on .NET 4.0).

My question to the Sharepoint Team is mainly this: Can we have a chance to see WF 4.0 in Sharepoint 2010 or we’ve to wait until Sharepoint 2010 SPx? Please don’t answer me to wait until SharePoint vNextNext…
