Using Tasks to implement the APM Pattern

Stephen Toub - MSFTJune 27, 2011Jun 27, 201106/27/11

Several times recently, folks have asked how to use tasks to implement the APM pattern, otherwise known as the Asynchronous Programming Model pattern, or the IAsyncResult pattern, or the Begin/End pattern. While moving forward we encourage folks to use a Task-based pattern for exposing asynchronous operation, the APM pattern has been the...

TPL Dataflow CTP Refresh

Stephen Toub - MSFTApril 13, 2011Apr 13, 201104/13/11

Today, we released a new CTP of TPL Dataflow, otherwise known as System.Threading.Tasks.Dataflow.dll. You can download this as part of the Microsoft Visual Studio Async CTP, which will also install the new C#/Visual Basic support for writing asynchronous methods, or you can install the DLL itself through the installer available on the ...

TPL Dataflow on TC Labs

Stephen Toub - MSFTJanuary 26, 2011Jan 26, 201101/26/11

After releasing a CTP of TPL Dataflow as part of the Async CTP, we had multiple requests for a standalone download for just the System.Threading.Tasks.Dataflow.dll. Thanks to everyone who asked for this, and as of this morning, such an installer for an updated version of the preview is now available! This is part of a ...

AsyncLazy

Stephen Toub - MSFTJanuary 15, 2011Jan 15, 201101/15/11

A question I’ve seen come up from time to time is “Why doesn’t Lazy<T> support asynchronous initialization?” It’s a fair question. After all, if you’re using Lazy<T> because you have an expensive resource you want to delay the creation of until it’s absolutely needed, it’s...

await anything;

Stephen Toub - MSFTJanuary 13, 2011Jan 13, 201101/13/11

One of the very cool things about the new await keyword in C# and Visual Basic is that it’s pattern based. It works great with Task and Task<TResult>, and awaiting those two types will represent the vast majority of uses, but they’re by no means the only types that can be awaited. The languages support awaiting ...

Await, and UI, and deadlocks! Oh my!

Stephen Toub - MSFTJanuary 13, 2011Jan 13, 201101/13/11

It’s been awesome seeing the level of interest developers have had for the Async CTP and how much usage it’s getting. Of course, with any new technology there are bound to be some hiccups. One issue I’ve seen arise now multiple times is developers accidentally deadlocking their application by blocking their UI ...

Processing Sequences of Asynchronous Operations with Tasks

Stephen Toub - MSFTNovember 21, 2010Nov 21, 201011/21/10

Of late, I’ve seen multiple folks asking about how to use tasks to asynchronously execute a sequence of operations. For example, given three synchronous functions: public string DoA(string input); public string DoB(string aResult); public string DoC(string bResult); you could invoke these functions with code like...

TPL Dataflow preview available for download

Stephen Toub - MSFTOctober 28, 2010Oct 28, 201010/28/10

As mentioned here, the Visual Studio Async CTP is now available for download from https://msdn.com/vstudio/async. Not only does this download add language support into C# and Visual Basic for writing asynchronous methods (in which you can easily “await” tasks), it also includes a new .NET library we lovingly refer to as &...

Language support for Tasks!

Stephen Toub - MSFTOctober 27, 2010Oct 27, 201010/27/10

Today is a very exciting day for Parallel Extensions, and indeed for all developers using C# and Visual Basic and who are interested in writing more responsive and scalable applications. At the PDC this morning, Anders Hejlsberg just announced the Visual Studio Async CTP, which you can download immediately from the landing page at https://msdn...
