This method returns true for success and false if an error occurs.


This function is called by the operating system loader for DLL assemblies. For executable assemblies, the loader calls the _CorExeMain function instead.

The operating system loader calls this method regardless of the entry point specified in the DLL file.

In Windows 98, Windows ME, Windows NT, and Windows 2000, the _CorDllMain function is called indirectly through a fixupin the operating system loader. In all other versions of Windows, it is called directly by the operating system loader.

For additional information, see the Remarks section in the _CorValidateImage topic.
