On some installations of Visual Studio 2008 for Studio Enterprise Edition, when in a native project right-clicking on a source file does not display the Compile option to compile a single file.  Why does this option show on some installations but not on others?

The Compile option in the Visual Studio 2008 content menu will only be displayed for a native project and only if the Microsoft C compiler is installed in Visual Studio 2008.  This is why the Compile option will not appear when using the Visual Studio 2008 Integrated Shell which does NOT have Visual C installed.  If you have a professional version of Visual Studio 2008 and you do not see the Compile option when right clicking on a source file in a native project then you should install the Microsoft C compiler.
