Async callback from C# to javascript

[823639792]

Now，I am using Jurassic in unity3d。
And I encountered a problem：
C#

        private class Transform
        {
            public int public_value = 789;
            public int Add(int i) {
                return public_value + i;
            }
        }

        XXXX.CallMemberFunction("Update", new Transform());

javascript

Update: function(transform){
		console.log(transform.Add(123));//this line throw exception
	}

and throw error: Cannot convert object of type Transform to an object (from TypeConverter)

And I find engine.SetGlobalValue() use "ClrInstanceWrapper" to wrapper it, use So I edit my code:

var trans = new ClrInstanceWrapper(engine, new Transform());
XXXX.CallMemberFunction("Update", trans);

It's run OK.

So my question is：
1、Is there any problem with this?
2、Why SetGlobalValue use ClrInstanceWrapper but CallMemberFunction not use it?

There are known problems with ClrInstanceWrapper and I'm not sure if it'll survive going forward. For that reason, I recommend that people inherit from ObjectInstance instead (documented here: https://github.com/paulbartrum/jurassic/wiki/Exposing-a-.NET-class-to-JavaScript).

On the other hand, what you're doing should work fine right now (especially for simple cases) and my progress on this project has been pretty glacial lately, so it should work for a while yet.
