If you want to help Microsoft to receive feedback about your way to using code, the .NET Framework Code Coverage Edition is what you need: it enables you to collect and upload data on how .NET Framework and Windows code is used by managed applications and components that you have developed.
This is an instrumented version of the .NET Framework and contains a tool that collects the code usage information behind the scenes. All you have to do is exercise your code under the watch of this tool, then save and send the data.
An interesting way to achieve compatibility and to have feedback about feature needed by users.
