\viewkind4\uc1\pard\lang2052\f0\fs20 Hi Bill,
\par
\par As for the additional "xxxSpecified" parameter, I think it is a webservice specific behavior for value type parameter/return value. For value type parameter in webservice, it support marking it as "nullable". However, since value type always contains a value, the .NET proxy generation will add an additional parameter for you to indicate whether this value has been set or not. You can try replace the "bool" type with another reference type such as string or a custom class .e .g.
\par
\par =================
\par [OperationContract]
\par
\par MyResult CanRunRef(string AppName, string Username, string Function);
\par .....................
\par \}
\par
\par
\par [DataContract]
\par public class MyResult
\par \{
\par [DataMember]
\par public bool CanRun;
\par \}
\par ================
\par
\par Then, the generated proxy method won't have that additional output parameter. For your scenario, I think you do not quite need to use it if the return value is always a valid/expected value. For more information about Nullable types in webservice, here is another form thread mentioned this:

\par
\par I have a web service hosting a WCF library, which works fine but produced a
\par strange signature when interacting with vs 2005/2.0 clients. My method takes
\par 3 strings and returns a bool as below.
\par
\par bool CanRun(string appName, string userName, string function);
\par
\par However the auto generated proxy in 2005 looks like this
\par
\par void CanRun(string appName, string userName, string function, out bool
\par result, out bool resultSpecified);
\par
\par I unserstand the new result parameter, but what is the resultSpecified
\par parameter that was created? It looks like it is always the same as the result
\par parameter, although admittedly I haven't tested this very thouroughly yet?
\par I'm pushing for WCF in our organization and don't want to get caught not
\par haveing an explanation of what is occurring here.
\par
\par Thanks,
\par Bill
