MyModeler BETA2 (April 2012) is available on codeplex.com on this link: http://mymodeler.codeplex.com/SourceControl/changeset/changes/16024
The source code is heavily re-worked from Feb 2012 BETA1. It is now full Boost (boost.org) ready and it can build either on VC10 and VC11. 64 bit support is not achieved yet. Unicode not yet. Windows 8 migration and branching is under work. This April 2012 step was the initiator for the Windows 8 migration project with XAML technology. Windows 8 offers great opportunities to native applications. Write once. Run on multiple devices and platforms without pain.
