It has amazing feature if you can use... Many of them are brilliant and that was the reason I wanted to purchase

OzCode provides many additional features during debugging sessions over the standard experience within Visual Studio. The features that assist me the most are the ability to search in collections when hovering over a variable (e.g. look for customer 123 in the collection) and the ability to see the anticipated values of variables or statements beyond the currently executing line (e.g. Oz-Code evaluates the upcoming code within the block and displays what the results will be, including if an error will be occurring).
