From today the development releases of my tools target a different version of the .NET framework. You’ll need .NET 4.0 from now on for all my tools. So be sure that you have it installed.
For scenProc I have used some of the new functionally of .NET 4.0 directly. As a result of the better parallel processing the image analysis of the feature detection step is now a lot faster. On my PC almost three times faster, but that depends on how many CPU cores you have as well of course.
