In dotNET with C# 4.0, How can I ensure that event that happens on an arbitrary thread X will call handlers in the same thread (or synchronization context) as the subscribing thread A, B, or C. I am trying to avoid having to put in threading-related code into handler method or event site. It would be really great if I wouldn't have to ...

Hi, I just start developping on android and i'm missing the EventHandler from c#. As a learning process, I started to write an EventHandler in java.

I hate EventHandler. I hate that I have to cast the sender if I want to do anything with it. I hate that I have to make a new class inheriting from EventArgs to use EventHandler<T>. I've always been told that EventHandler is the tradition and blah, blah...whatever. But I can't find a reason why this dogma is still around. Is there a re...
I've got a UIPickerViewModel that's supposed to fire an event when its selected value changes, but by the time Selected is called, the EventHandler is null.

I wasn't expecting to come across this error. I imagine I'm doing something wrong somewhere else. I have an MVVM application. My model can serialise its self using a BinaryFormatter. This was working fine. Today I added in an event handler to my model, and the viewmodel that contains the model subscribes to this event. Now when I try...
I wish to create a custom EventHandler that can have any number of objects as its parameters and the objects it gets isn't known in advance. I know I can pass it an Object[] but what I would like is something similar to MyEventHandler someCustomEvent(Object obj1, Object obj2, Object obj3) where the number of objects can be 0 or 10 if...
