Did you know about the feature submission and votings sites we run in dev div at Microsoft?

• Silverlight feature suggestions
• WPF feature suggestions
• WCF RIA Services feature suggestions
• ASP.NET feature suggestions

Each of those sites is monitored by community PMs like me, Tim Heuer, Jesse Liberty, John Galloway and Scott Hanselman as well as product team members. I've been personally interacting with WPF planning teams, and they have requested this information as input into their planning process. We can't guarantee that the features list are 1:1 with feature dev priorities, but if you have a feature you really want to see in the next version of your favorite product, this is the place to let us know.

Submit and vote. Get your developer friends to submit and vote. If your mom develops in .net, get her to submit features and vote. Get your them all to vote on cool things you want to see in the next versions.
