Resolved Single compilation

Yes, ideally, we would like minimize the amount of compilation going on.

Today, if you are in your IDE, you change a file and you compile it in the IDE but if you switch back to Unity, Unity will do exactly the same operation. It is quite a waste of time. Also, what you compile in the IDE is often, not necessarily what you are really going to compile in the Unity Editor (the compilation pipelines are completely different), so we know that the current experience is very unpleasant.

What we would like to achieve is that:

1. What we compile in the IDE is using the exact same compilation pipeline used in Unity.
2. If you compile in the IDE, we should not have to recompile in Unity.

In order to achieve this, we will need to move away from our custom compilation pipeline in Unity, and use the more standard and ubiquitous MSBuild. The same MSBuild that is used to compile standard .NET projects these days.

The benefit of using MSBuild will also open a lot more opportunities for our users (e.g NuGet, customize the compilation pipeline...etc.)
