= Using the Visual Studio Plug-in = The debug engine MagoNatDE can be registered to allow source-level D debugging in Visual Studio. This has been tested with Visual Studio 2005 and 2008; and it's assumed to work as well with VS 2010. There are two ways to use the debug engine with VS: thru a project system or stand-alone. The following steps describe how to run the debugger without the help of a VS project system. Once they're finished, you'll find a new item at the top of the Tools menu that you can use to launch the debug engine for the open project. For more details, see the file [source:/trunk/ReadMe.txt ReadMe.txt] at the root. 1. Register the COM server MagoNatDE.dll. 1. Import into the registry the settings appropriate for your system and Visual Studio version. They can be found in the [source:/trunk/Install Install] folder. 1. Put the MagoDELauncher Add-In where VS will look for it. If you're using a project system for D that has integrated the Mago Debugger, then you can start a debug session as you normally do by using the Start Debugging command (F5). If you're building a project system for D, you can find the GUID for the debug engine in all of the !EngineMetric registry files.
