Represents the file to be built by this build provider implementation.
Assembly: System.Web (in System.Web.dll)
The virtual path of a BuildProvider object is the path to the file that is being compiled by the build provider. For example, if you have configured a custom BuildProvider class to build all files in the Web site with the custom extension of .abc, if your Web site is named WebSite1, and the Web site contains a file named Example.abc, the property contains the value /WebSite1/Example.abc.
The file extension of each file within the application determines the file type, and the corresponding build provider for the file type. The ASP.NET build environment initializes a BuildProvider object for each file based on the file type, and uses the BuildProvider methods to generate source for each file.
For more information about configuring a build provider, see buildProviders Element for compilation (ASP.NET Settings Schema).
