This Software Devel- opment Kit (SDK) contains all the documentation and interface files that are needed to write code that interacts with VirtualBox. 1.1 Modularity: the building blocks Visual Basic or C#), then you can use the COM/XPCOM API directly. VirtualBox comes with all necessary files and documentation to build fully functional COM applications. For an introduction, please see chapter VirtualBox also comes with WSDL files that describe the services provided by the web ser- vice. You can find these files in the sdk/bindings/webservice/ directory. These files are understood by the web service
