Native API  , IRIS 2019 regression vs Cache .Net provider  1. checking the native API, with .net provider, from IS docs, I realize, that it is not possible to wrap objectSricpt Class with .NET (C# for example) pure Class with it's methods/properties and make pure instance syntax of: new myNetClass - as wrapper of irisClass. as I realize, you can run  .Net Class , only with .Invoke or iris.ClassMethodVoid("class.name","method") such syntax, cannot execute event driven on proprety change, let say, with it's build in mechanizm in .Net   2. IRIS 2019. this version is missing the class IRISObject  ? I have to upgrade to IRIS2021 ?
