Most online resources around async/await assume you’re developing client applications, but does async have a place on the server? The answer is most definitely “Yes.”
This article will present ways to design and refactor code for better testability, and demonstrate how this will influence the tests. The solutions are applicable to code that takes advantage of async and await, as well as code based on lower-level multithreading mechanisms from earlier frameworks and libraries.
An await expression cannot occur in the body of a synchronous function, in a query expression, in the block of a lock statement, or in an unsafe context.
In case you missed it, Node now supports async/await out of the box since version 7.6. If you haven’t tried it yet, here are a bunch of reasons with examples why you should adopt it immediately and never look back.
Microsoft and the .NET community have made asynchronous programming very easy with their implementation of async await in C#. The latest versions of ASP.NET heavily utilize it to improve performance. Many performance monitoring and profiling tools struggle to support and visualize the performance of asynchronous C# code.
