When you create a project, you can specify the include files and macro definitions that will be used by the built-in parser to create the configuration. If the project has been built with debug information, you can have the built-in parser automatically search for the include files and macro definitions for each compiled source file.
To specify additional code assistance configuration information that will improve the accuracy of the code assistance features of the IDE for a project, use the Configure Code Assistance wizard. To start the wizard, right-click your project and choose Configure Code Assistance. To learn more about configuring Code Assistance and the Configure Code Assistance wizard, see the relevant help sections in the IDE.
