Asynchronous Programming Models in C#

Pattern	Description	Based On	Notes
Thread based	By creating `System .Threading .Thread` instance	Managed Thread	Expensive, not recommended
Standard `BeginXxx` and `EndXxx` methods	By calling `BeginXxx` method with a user callback; calling `EndXxx` inside that user callback	Thread pool	Widely used, standard, recommended, support cancellation and continuation
ThreadPool	By calling `ThreadPool`’s static `QueueUserWorkItem` method	Thread pool	Widely used, recommended use as much as possible
Delegate	By calling Delegate’s `BeginInvoke` and `EndInvoke` instance methods	Thread pool	Less used
Event based	By subscribing to the appropriate event and calling the appropriate method	Thread pool	Avoid use as much as possible, not recommended
Task based	By creating `System .Threading .Tasks .Task` instance	A specified task scheduler	Recommended, supports all features of a thread pool pattern, and has many other features
`async` method and `await` expression	By using `async` and `await` keywords	Task based pattern	The new C# 5.0 asynchronous pattern
