I have Unity Personal 5.3.2f1 64bits on my Windows 8.1 computer, and I use monodevelop 5.9.6 which is implemented in unity.
Recently, when I create a new c# file on unity, and when I open it, Monodevelop crash on loading this new file. If i create this new file on the Monodevelop interace, it works…
But… I can open without problems older files on Monodevelop or Unity tree project.
