How do I create a generic method with a generic in the where clause? (Man that's clear as mud!)

eventaggregator

Is there a way of doing this:

protected void SubscribeToEvent<TEvent, TPayload>(Action<TPayload> a_action)
    where TEvent : CompositePresentationEvent<TPayload>
{
    TEvent newEvent = _eventAggregator.GetEvent<TEvent>();
    SubscriptionToken eventToken = newEvent.Subscribe(a_action);

    _lstEventSubscriptions.Add(new KeyValuePair<EventBase, SubscriptionToken>(newEvent, eventToken));
}

without requiring the user to specify a TPayload parameter?

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

I'm hashing a file with one or more hash algorithms. When I tried to parametrize which hash types I want, it got a lot messier than I was hoping. I think I'm missing a chance to make better use of generics or LINQ. I also don't like that I have to use a Type[] as the parameter instead of limiting… >>> More
