We recommend using Visual Studio 2017

In terms of the debugger architecture, a port:

  • Is a container for a set of processes running on a server. For example, a port might represent a connection to a Windows CE-based device by a serial cable, or to a networked non-DCOM machine. One special port, called the local port, contains all the processes running on the local machine.

  • Can identify itself by name or identifier.

  • Can enumerate all processes running on the port and launch and terminate these processes.

  • Is represented by an IDebugPort2 interface, which is created by passing an IDebugPortRequest2 argument to AddPort.

Visual Studio supplies a default port that handles all Windows-based processes, native and managed. A custom port must be implemented for connections with external devices that are not Windows-based. To supply such custom ports, a custom port supplier also needs to be implemented.
