Broker ActiveX Control with .NET

How do you add the Broker ActiveX Control to the project references in Visual Studio for EntireX 951? I do not see anything referring to Broker ActiveX Control.

Do you see it when running dcomcnfg? If not, you probably have not registered it.

we see EntireX Broker ActiveX Control in Component Services (screenshot below), but it is not listed in Visual Studio when doing Add Reference
