    Code (CSharp):
    1. string rtdir = System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory();
    ArgumentException: Invalid path
    at System.IO.Path.GetDirectoryName (System.String path) [0x00000] in <00000000000000000000000000000000>:0

    why il2cpp has runtime directory?

    I don't believe that IL2CPP currently supports this API. It might be something that we can add support for (at least on some platforms), but I'm curious about why your application needs to know the directory where the .NET runtime is installed.

    Hi, we're integrating Python into Unity. And it requires a lot hack on il2cpp(Mono now is 100% working!).
    The reason why we wanna do this, is that server side's code is developed with Bigworld and we wanna both side share the same code base.
    And some one say with Mono.Cecil, manually injecting IL code to delegate can bypass that API, it there anyway to do it? Curious...

    I don't think there is any need to inject IL code to handle either of these cases. I've responded on the other forum thread about the MonoPInvokeCallback issue.

    For the GetRuntimeDirectory method, you can submit a bug report, and we will investigate the complexity of implementing it.

    Ok, i'll do it later. But plz help us with MonoPInvokeCallback, any detailed information would be appreciated, because we can't implement it like the normal case.

    I can send the complete sample code for testing.
