    // This function exists because UnityEngine.dll is compiled against .NET 3.5, but .NET Core removes all the overloads
    // except this one. So to prevent our code compiling against the (string, object, object) version and use the params
    // version instead, we reroute through this.
    // </OUTDATED>

    // This was added to support .net Core in UWP Metro Apps. We no longer require this wrapper so it can be removed

    // TODO: remove this once all package references have been removed as it prevents some overloads being used which increases the amount of cases where a params array is allocated when this function is called
