All about Async/Await, System.Threading.Tasks, System.Collections.Concurrent, System.Linq, and more…
March 25, 2012Mar 25, 201203/25/12I get this question a lot:
“Task implements IDisposable and exposes a Dispose method. Does that mean I should dispose of all of my tasks?”
Summary
Here’s my short answer to this question: “No. Don’t bother disposing of your tasks.”
Here’s my medium-length answer: “No.
March 24, 2012Mar 24, 201203/24/12Lately I’ve received several questions along the lines of the following, which I typically summarize as “async over sync”:
In my library, I have a method “public T Foo();”. I’m considering exposing an asynchronous method that would simply wrap the synchronous one,
March 14, 2012Mar 14, 201203/14/12Every now and then, I get this question: “is it ok to use nested Parallel.For loops?” The short answer is “yes.” As is often the case, the longer answer is, well, longer.
Typically when folks ask this question, they’re concerned about one of two things.
March 6, 2012Mar 6, 201203/6/12Are you using the new System.Threading.Tasks.Dataflow.dll library, either from its CTPs or from the .NET 4.5 Developer Preview or Beta? We’d love to hear about it, and if you have time, what your experiences have been (good or bad). What kind of solution are you building,
March 5, 2012Mar 5, 201203/5/12After my previous post, I received several emails and comments from folks asking why I chose to implement ForEachAsync the way I did. My goal with that post wasn’t to prescribe a particular approach to iteration, but rather to answer a question I’d received…
March 4, 2012Mar 4, 201203/4/12Jon Skeet recently asked me how I might go about implementing the following “asynchronous ForEach” behavior:
For each element in an enumerable, run a function that returns a Task<TResult> to represent the completion of processing that element. All of these functions may run asynchronously concurrently.
March 3, 2012Mar 3, 201203/3/12The C# and Visual Basic compilers implement support for async/await by generating code that utilizes some specific types in the underlying framework. These types include the “awaiters” used to await things (like Tasks) as well as the “builders” used in handling the lifetime of an async method’s invocation.
March 3, 2012Mar 3, 201203/3/12Thanks to everyone who attended my “The Zen of Async” presentation on Thursday at the MVP Summit. As I’ve had several requests, here are the slides and code for the talk.
