To create a launch configuration for debugging a mixed language application, complete these steps:
If you want to search for all instances of the source filename in the source search path, select the Search for duplicate source files on the path check box. If you select this check box and the debugger finds multiple instances of the filename, you will be prompted by a dialog box to choose the correct source file.
After you have saved a debug launch configuration, you can edit it. For further information about editing debug launch configurations, see the related task.
If you are launching a Web object for debug, once you have launched a debug session with the debug adapter, you will need to launch the Web object by entering its URL in a browser.
