Hello,
We have been using your framework for about 2-3 weeks, we are creating a Node Editor and we have been testing the showcase app "Diagram__Builder_2015" in Windows 10 x64 and Visual Studio 2015.
The exe that appears in the samples runs well however when you try to drag nodes to the grid it crash, we thought that could be an old example but when we try to run the source code from Visual, it crash again when you try to drag a node.
We are sending you this because this could be a issue/bug and we want you to know.
Visual Studio says that the error is "FormatException was unhandled, System.FormatException occurred in PresentationCore.dll".
Also there are some png files missing and the perfomance of the example is not the best.
We are really happy with your product and we wanted to share some feedback to help.
Thanks.
