Remarks
When this option is used, the application will be subject to virtualization on Windows Vista unless you provide an application manifest in a Win32 Resource file or during a later build step. For more information about virtualization, see New UAC Technologies for Windows Vista.
In Visual Studio, set this option in the Application Property page by selecting the Create Application Without a Manifest option in the Manifest drop down list. For more information, see Application Page, Project Designer (C#).
