Hello,
I have the following simple client code that needs to auth against a server. The server needs HTTP Header Auth to be added before doing any work.
The problem is I get this error:
Object reference not set to an instance of an object.
 
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click Dim httpRequest As New HttpRequestMessageProperty() ' ERROR ON THE FOLLOWING LINE ' OperationContext.Current.OutgoingMessageProperties.Add(HttpRequestMessageProperty.Name, httpRequest) Dim authByte As Byte() authByte = Encoding.ASCII.GetBytes("aaaa:nbbbb=") Dim base64 As String = Convert.ToBase64String(authByte) httpRequest.Headers.Add("Authoriazation", "Basic " + base64) End Sub ...

Go to the complete details ...
