Unity is using files loaded by Assembly.LoadFrom even after the game simulation is terminated

    I have a game that loads .dll files into the runtime with Assembly.LoadFrom(). When I have terminated the game simulation in the editor, Unity is still using these files as I can't delete, rename or move them. Is there a way of stopping this from happening?

    Dll loading code:

    foreach (var file in dir.GetFiles())
    if (file.Name.EndsWith (".dll"))
    Assembly ass = Assembly.LoadFrom (file.FullName);

    Based on this page: https://msdn.microsoft.com/en-us/library/mt632258.aspx
    it seems that you need to load your assemblies into a custom AppDomain and then unload the AppDomain.
    I don't know if this will work in Unity, but it is worth a try.
    I suggest calling the unload code from some OnDestroy() or OnDisable() function

    As far as i know, Unity is already loading all scripting assemblies into a custom "scripting" app domain that gets unloaded as you exit play mode.
