    You should either use the attribute, or manually verify the COM
    security settings are correct following deployment

    Add this reference through the .NET tab, not COM tab.

    See my asnwer abov
   
    >2. When I using System.EnterpriseServices (using transactions), after I publish it in COM+, is not necessary to add a reference from COM+?, in other words, like .NET Framework use that classes for transactions, .NET Framework will do COM+'s work? and for that is I have to add my .DLL assebly directly?
   
    Not unless the client code inself requires that
