Debugging your Addin
You can debug an addin by going into the project properties screen, and setting KioWare as the external program to start:
C:\Program Files (x86)\KioWare Client Platform\KioWare Client.exe
Close the project properties and add breakpoints as necessary. Then, start the debugger using the green triangle at the top. Your breakpoints should now hit as expected. Ideally, you have two monitors for debugging. The primary monitor is where KioWare will start, and you can step through code in Visual Studio on the second monitor.
