Today .NET department meeting was devoted to problems of asynchronous programming and parallel code execution. Dmitry made a rich information presentation about various asynchronous programming models existing in .NET. Dmitry made a short preview of new C# 5 language features related to new async and await keywords. He also made a preview of parallel language integrated query extensions and Task Parallel Library Dataflow. Topics discussed:
- Basic concepts of asynchronous programming (Process, Thread, Thread pool)
- How does operating system works with asynchronous input and output
- APM pattern
- Event based asynchrony
- Task based asynchrony
- New compiler features related to async and await keywords
- PLINQ
- Dataflow
- Synchronous vs. asynchronous server implementations and their scalability
There are some screenshots from presentation:
