Unable to connect to WFA Webservice from .NET project

Hello All,

How do I configure a .NET C# project to connect to a WFA Web Service please? Running a test from PowerShell works fine. When using the same credentials from .NET C# console project, an error "System.InvalidOperationException" in system.xml.dll "There was an error reflecting return" when trying to open a client connection

George,

Can you share some details here:

1. I assume you are using WFA SOAP web services. Correct?

2. What is your WFA version?

3. Can you share a bit of your code?

Hi George:

Is this problem resolved?

If it is not resolved, can you please download a 3rd party soap client,

for example, http://sourceforge.net/projects/soap-sec/, and check

if the connection succeeds.

Regards

Abhi
