'Usage
Dim instance As EventPattern(Of TEventArgs)

public class EventPattern<TEventArgs> : IEquatable<EventPattern<TEventArgs>>
where TEventArgs : EventArgs

generic<typename TEventArgs>
where TEventArgs : EventArgs
public ref class EventPattern : IEquatable<EventPattern<TEventArgs>^>

type EventPattern<'TEventArgs when 'TEventArgs : EventArgs> =  
    class
        interface IEquatable<EventPattern<'TEventArgs>>

Remarks

The FromEventPattern operator works with events that take an object sender and some EventArgs, and uses reflection to find add/remove methods. It then converts the given event into an observable sequence with an EventPattern type that captures both the sender and the event arguments.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
