      The Readme displays information about samples.

    • Visit the Visual Studio 2008 Samples Web site. The most recent versions of samples are available there.

    • Locate samples on the computer on which Visual Studio is installed. By default, samples and a Readme file are installed in drive:\Program Files\Microsoft Visual Studio 9.0\Samples\lcid. For Express editions of Visual Studio, all samples are located online.

For more information, see Visual Studio Samples.
