This is a significant step because the .NET Compact Framework SDK is heavily licensed, unlike the .NET SDK available for free from MSDN. Thanks to PocketPC#, now you can build Window.Forms C# applications for PocketPC without submitting to Microsoft's exhorbitant SDK licensing fees. Portability to embedded/low-end hardware is one of Portable.net's stated goals. DotGNU Portable.net also works on 9 major CPU architectures according to gentoo's portage. The Darwin-ports features a cool package with Windows.Forms for Mac OS X. Handhelds like iPAQ or Zaurus have also ports (the iPAQ one features Windows.Forms). Esoteric hardware like the Sony Playstation 2 or the Microsoft XBox can also run Portable.net."
