service

I have an application which exposes lots of interfaces via net.tcp protocol, using both SecurityMode.Transport and SecurityMode.None (I really need support for both).

My whole application is written in a DLL file. I have a form which consumes this DLL and now I made a Windows Service to consume this DLL.

The problem is, when this windows service goes up, the insecure service throws this exception:

Stream Security is required at http://www.w3.org/2005/08/addressing/anonymous, but no security context was negotiated. This is likely caused by the remote endpoint missing a StreamSecurityBindingElement from its binding.

In the client side, nothing has changed.

Is there any reason for this behaviour? The program is exactly the same. When I run the same test with the form app, it works...

ps: I've already tried running the windows service as: SYSTEM, NETWORK SERVICE and my user account (which runs the form app)

Thanks

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
