Debugging in Epicor

How do you debug in Epicor? Is there some sort of writeline or debug.print? I could use?

Use Visual Studio (Look in the manual it tells you how, Ice Customization Guide , or Help F1 search for Visual Studio)

I use visual studio already with your plugin. I would like a way to print out text rather then doing messageboxes tho.

No i mean use visual studio for debugging again check the help its all there
You can place breaks in your code, and much more.
