go to post Colin Nagle · Jul 5, 2019 Hi Alexander,Thanks very much for that, looks like what we're after!For any IS folks out there, I think there's a typo in the readme:-'1) Remove references to InterSystems.Data.CacheClient.dll from the .NET project. Add references to InterSystem.Data.IRISClient.dll *and* InterSystem.Data.IRISClient.dll. If an application needs only ADO.NET features it can include only InterSystem.Data.IRISClient.dll but applications using Bindings features must include both dlls.'I think the second reference to InterSystem.Data.IRISClient.dll should be InterSystem.Data.Bindings.dll?
