@juanfranblanco Hi, let me thank you for the Nethereum first, superb product. I do have an issue though with iOS (Unity) :). I get No parameterless constructor defined for Nethereum.Unity.RpcModel.RpcParametersJsonConverter. It's a simple call to Rinkeby account to check balance, it works in editor and mac build, did not try Android yet but will. Unfortunately it does not work on iOS (Simulator) i get the before mentioned error, to which only link i found was in your post regarding WebGL. Is Nethereum working with Unity on iOS? I have latest xcode, latest unity (2017.3) and Nethereum.Unity 2.2.1. Thanks for your help.
