Just found EmitPushBigInteger, will refactor and resubmit

Not every SC accepts params, so this would throw an error for any SC which doesn't.

I think there could be different solution to your problem.

Could you send me a script hash you're trying to invoke, and the params you're trying to invoke with? That way I can test :)

Alright, I'm looking at the ICO_Template right now, and it looks like the 2nd param is a variable length array/object of more params, in which case your solution makes sense.

However, this approach would break invokes for any invoke that doesn't have variable length params objects.

I can work on a fix for the Invoke method which will accept that type of argument set...
