Using ACF Attributes in an IDL File

You can use the /app_config MIDL compiler option to specify binding handle attributes in the IDL file rather than in a separate ACF file. Specifically, you can apply the auto_handle, implicit_handle, and explicit_handle attributes to the header of an RPC interface in an IDL file. Consider using this option if your RPC application doesn't require other ACF attributes, and if you don't require strict OSF-DCE compatibility.
