I had a basic plugin working in Unity 3 that I had coded in C++ and compiled into a DLL file. It only did simple things like addition or returning a string, but it worked correctly. However after upgrading to the Unity 4 beta Unity now crashes as soon as I try and call a function from my DLL. I’ve also tried with the “simplest plugin” example project supplied here and it also crashes as soon as it attempts to call an external function.
Has the process for using plugins changed for Unity 4? Has anybody else also had this issue?
