The IIOP Toolset provides a graphical userinterface to analyze end-to-end connectivity thru firewalls and NAT-gateways between the location of CORBA client and the service endpoint of the CORBA server.
Remoting.Corba is a .NET library that provides IIOP support for the .NET Remoting system. This allows developers to write applications in C# and Visual Basic .NET that interoperate with CORBA systems, without need for an ORB or a SOAP/CORBA bridge.
