Async/Await: It’s time

I wanted to briefly mention a blog post which I wrote on the particular blog. It is a product centric announcement around the Particular Platform about the move towards an async-only API. Although it is product centric I believe this post contains a lot of valuable information around async/await and its benefits and caveats. In my biasedĀ opinion, it is definitely worth a read.

Async/Await is a language feature introduced in C# 5.0 together with Visual Studio 2012 and the .NET 4.5 runtime. With Visual Studio 2015 almost ready to be shipped to end-users, we can see that async/await has been around for quite some time now. Yet NServiceBus hasn’t been exposing asynchronous APIs to its users. Why the await?

We have been carefully observing the adoption of async/await in the market and weighing its benefits against its perceived complexity. Over the years async/await has matured and proven its worth. Now the time has come to discuss our plans regarding the async/await adoption in NServiceBus and our platform.

TL;DR

  • Future versions of the NServiceBus API will be async only.
  • Synchronous versions of the API will be removed in future versions.
  • Microsoft and the community have made this decision for you, by moving toward making all APIs which involve IO operations async-only.
  • Don’t panic! We will help you through this difficult time.

You’re going to be blown away by the additional benefits that asynchronous NServiceBus APIs will provide. But first, let’s review why asynchronous APIs are such a big deal in the first place.

If you want to learn more about async/await, I suggest you read the full blog post originally posted on the particular blog.
