Cannot revert to .Net 3.5 (Mono 2.0) build

    Regardless of how hard I try, I cannot get Unity to go back to the .Net 3.5 Framework.

    From my editor log:

    Initialize mono
    Mono path[0] = '/Applications/Unity/Unity.app/Contents/Managed'
    Mono path[1] = '/Applications/Unity/Unity.app/Contents/Mono/lib/mono/2.0'
    Mono config path = '/Applications/Unity/Unity.app/Contents/Mono/etc'

    ...

    -----Compiler Commandline Arguments:
    Filename: /Applications/Unity/Unity.app/Contents/MonoBleedingEdge/bin/mono
    Arguments: '/Applications/Unity/Unity.app/Contents/MonoBleedingEdge/lib/mono/4.5/mcs.exe' @temp/UnityTempFile-d726fd46e71d14e6b9e6f879503937fa

    Why is it compiling with MonoBleedingEdge if I specified in my player settings to use 3.5?

    I need this to be fixed, because I'm getting the dreaded forever compiling spinner whenever I make a change in Rider while the editor is open. In other words, the second compile (after clearing my ScriptAssemblies folder) always hangs.

    Out of desperation, I've even tried monkey-patching the 2.0 directories into 4.5, and I'm stuck on mscorlib.dll not found. I just need to revert to 3.5 because the number of bugs and the completely flakey building in 4.5 is utter madness. Please advise.

    I have no 4.5 assemblies.

    The complete editor log in 4.5, which hangs unless I delete ScriptAssemblies:

    We always compile managed code using the C# compiler from MonoBleedingEdge. It uses a new compiler but still references the proper APIs (.NET 2.0, etc). It has been like this since Unity 5.6 I believe.

    I am not sure what is causing your hang but this is correct behavior to use the compiler from this location.

    I am not sure what is causing my hang either. The editor logs certainly aren't telling me.

    Try to sample the process using Activity Monitor.

    If you look at processes hierarchically in Process Monitor are there any child processes under Unity still running?
