There are many tools that can be licensed from http://particular.net/ which aid in developing and monitoring NSB components. NSB components include endpoints, messages, and services. Components include any of the configured items on the IBus.
ServiceMatrix is an extension plugin that can be installed into Visual Studio 2012. This plugin creates an NSB canvas that creates various NSB components through wizards, which will generate C# code to be used for the ESB. ServiceMatrix simplifies and standardizes the development lifecycle by generating code to match diagrams designed in the NSB Canvas, and helps developers create NSB-standardized code from the NSB Visual Studio wizard. NSB wizards assist in learning how different pieces make up an NSB application from end to end. ServiceMatrix also creates skeleton pieces and associate generated C# code to run an end-to-end NSB solution with less effort from the developer.
