Question

I have a class

Public Class NotifierAuthHeader
    Inherits SoapHeader

    Public HandlerId As Integer
    Public Guid As Byte()
End Class

which I use in webservice in following methods:

<OperationContract()><WebMethod()> _
public Function GetTestNotifierAuthHeader()
    Dim testNotifierAuthHeader as NotifierAuthHeader=new NotifierAuthHeader()

    return testNotifierAuthHeader

and

<SoapHeader("auth", GetType(NotifierAuthHeader), Direction:=SoapHeaderDirection.In)> _
    <OperationContract()> <WebMethod()> _
    Public Function GetUnreadInboxMessages(ByVal handlerId As Integer, ByVal customerGuid As String) As String

The problem is, I can’t compile client WPF application which has this webservice as servicereference, because it say me, that he doesn’t know any NotifierAuthHeader class.

private ServiceReference1.Service1SoapClient _ws = new ServiceReference1.Service1SoapClient();

//Here it says about this error

private ServiceReference1.NotifierAuthHeader _authHdr;

Funny thing is, that I can use GetTestNotifierAuthHeader method at client, but type of return object is..object, not NotifierAuthHeader

What could be wrong with my code?

asmx service is 3.5
and wpf app is 4.0 c#.

Try making your your NotifierAuthHeader serializable

<Serializable()>Public Class NotifierAuthHeader 
    Inherits SoapHeader 

    Public HandlerId As Integer 
    Public Guid As Byte() 
End Class
