Developers can create multi-touch enabled applications on Windows 7. However, Windows 7 comes with the .NET Framework 3.5 SP1, and developers will have to write extra code to implement some touch scenarios that are available in the next .NET release, WPF 4 (currently in Release Candidate) and Surface Toolkit for Windows. The Touch project at CodePlex was created to bridge the gap.
