Async involves some new concepts. They're not difficult; just unfamiliar. Over the past year Lucian Wischik has been watching how people use async/await in C# and VB. This series distils out the three top async patterns and anti-patterns. Tips: Async void is for top-level event-handlers only, and…

Async Tip #1: Async void is for top-level event-handlers only, and event-like things. Don't use it elsewhere in your code. Slides are available on Lucian's blog. Async void is a "fire-and-forget" mechanism: the caller is unable to know when an async void has finished, and the…

Async Tip #2: It's crucial to distinguish CPU-bound work (should be done on threadpool) from IO-bound work (which needn't). You can download slides for this talk from Lucian's blog. I remember reading an old Android dev blog post. It said: "1. A good practice in creating responsive…

Async Tip #3: You can wrap events up in Task-returning APIs and await them. This can dramatically simplify code. Slides and source code are available on Lucian's blog. This video introduces a new pattern for dealing with events: you can await them! Now why would you want to do that? Well,…

Lucian Wischik, the Visual Basic language Program Manager, digs into many of the new features in VB11. This was recorded at DevConnections a few days ago.

What is Roslyn? Traditionally, compilers are black boxes – source code goes in one end and object files or assemblies come out the other end. The Roslyn project changes that model by opening up the Visual Basic and C# compilers as APIs. These APIs allow tools and end-users to share in the wealth of…

Lucian Wischik is an engineer who spends a great deal of his time making Async magic happen in the C# and VB compilers. With the recent release of Visual Studio Async CTP SP1 Refresh, come several low-level improvements in how asynchrony is orchestrated by the compiler infrastructure.…

Roberto Leiton, CEO of ArtinSoft, and Tim Huckaby, Founder of InterKnowlogy, launch an interesting discussion around resurrecting fragile legacy applications. ArtinSoft, a leader in VB6 to VB.NET and C# migrations, has helped numerous enterprise companies rescue their application investments.…

Meet some of the key folks behind the Async CTP, which contains a preview version of C# and VB.NET that contain two new modifiers, async and await (and iterators for VB.NET!), that will make it much easier to compose asynchronous code for .NET. Great work, C#, VB and Parallel Platform teams (and…

Lucian Wischik digs into the new VB functions and iterators being developed for asynchronous development. You can get an early look at these new features, available as the Async CTP, today! Give VB.NETAsync a try. In this whiteboard-heavy conversation, Lucian demonstrates how to make…
