At some point in the 5.x cycle IL2CPP will be in place for windows standalone builds. When that happens reflection.emit will no longer be supported on desktop builds (it is already not supported for most mobile platforms). Is there any plan to look at an alternative approach to Castle Dynamic Proxy? I realize, based on how long the new GUI took, this could be years a away or it could be months. There are a ton of ways to deal with sending operations to the server, so it's probably not a big deal if IL2CPP comes out tomorrow, I was just curious to see if there was an alternative approach being considered.
