+# Threads, Tasks and More
+
+### Talk overview
+This presentation recaps some of the basics of writing code that makes use of threads, tasks and asynchronous features in C#. It is a modified version of a talk the author has given to his team at Microsoft.
+
+This is an intermediate level talk aimed at developers still learning how to write parallel and async code in C#.
+
+Material covered includes:
+
+* What are threads?
+* What are tasks?
+* What are the rare cases you would want to use threads directly instead of tasks?
+* What is asynchronous code?
+* What actually happens when we await an async method?
+* Common misconceptions about async code and parallelism.
+* How continuations work.
+* How to run multiple async methods in parallel.
+* The perils of mixing sync and async code.
+* The non-zero cost of making code async.
+* Using Task.Yield to avoid blocking the caller.
+* The purpose of the Thread Pool.
+
+Finally, the talk concludes with a demonstration putting some of these conepts together by illustrating the thread pool thread creation algorithm, how high bursts of activity can lead to disaster when executing I/O bound tasks, and how using async solves this problem beautifully.
