The license of NModel is Ms-PL extended with an additional item that makes clear that the current version of NModel depends on the graph layout component GLEE. This dependency is temporary and as soon as the dependency to GLEE is removed, or if GLEE is not used, the license is the same as Ms-PL.

Instead of GLEE that is free for academic use but is not supported any more, one can adapt MSAGL (the successor of GLEE) for NModel.

There has been some confusion regarding the license of MSAGL.
The license of MSAGL is a commercial one.
