    Reproduced on Unity 2018.3.0b8, only happens when Scripting Runtime set to .NET 4.x . Error disappears when I set .NET 3.5.

    The thing I noticed is error happens when loading DLL built with .NET 3.5

    This bug has been fixed in Unity 2018.3

    Currently, there is no plan to backport it to older versions.
    Use the newer Unity version to avoid encountering this bug :)
