authentication

I'm consuming a web service from C#, and the web service requires a login call and then uses cookie sessions. The web service will time out sessions after a certain timeframe, after which the client will have to re-login. I'd like to find a way to automatically catch the soap fault the service sends back in this scenario, and handle it by re-logging in and then retrying the previously attempted call.

I would prefer to do this somehow automatically for all the web service methods in question, rather than having to manually wrap the calls with the retry logic.

Suggestions?

Dynamic Type to do away with Reflection

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
