I've been trying to mess around with the SGen garbage collector's configurations and as I've seen here, here, and in the mono man page, I've got a few environment variables to work with.
As shown in this image, I added them to my project (checked inside the csproj too), and they only get ignored when i run my app. I got all my environment variables using Environment.GetEnvironmentVariables() and neither MONO_GC_PARAMS or MONO_GC_DEBUG were there.
So my question is how do I use environment variables in a MonoTouch project?
