I have used the InterSystems.Data.IRISClient.ADO library fo .NET, but I also want the ability to call class methods in Ensemble and other earlier builds.
I assumed the API would be the best way as it allows me to inserts classes, but if it is not possible to call methods I would appreciate any other ways achieving this.
Using Atelier API, for such task looks a bit strange. Did you look at the documentation about what is available for direct use in .Net?

Atelier API is just for IDE, it's not supposed to call any custom call.
There is a way, that you could call SQL Proc, via SQL Query. But it is not what I would recommend
