Support for Unity3D
Too high effort for low demand.
Tristan Chambers commented
I am very interested in PostSharp for the Unity 3D platform. It would allow us to use our powerful debugging tools more easily and automatically. It would also allow us to make more capable systems and streamline the scripting of our gameplay. I'm most interested in the serialization, networking and profiling opportunities this could open up.
We are currently in the ongoing process of moving our code base into DLL's to reduce our compile times and I would like to eventually take advantage of PostSharp on these external projects. However most of the code base that can actually take advantage of PostSharp are difficult to remove from the Unity project. (Mostly because of GUID references to MonoBehaviours and Prefabs) So it would be nice to have PostSharp integrated into Unity.
