Scheduling one or more background tasks is almost inevitable when building robust, self-sustaining APIs with .NET. A few packages have been around for years, such as Hangfire and Quartz.NET. ASP.NET Core allows background tasks to be implemented as hosted services. However, you might need something more customizable and lightweight with...

“What the hell was I thinking?!?” It’s 1:30AM and I am staring at a piece of code I wrote no more than a month ago. At the time it seemed like a work of art. It all made sense. It was elegant and simple and amazing. Not anymore. I have...

async void methods in C# are a source of a lot of problems for many developers getting into writing async await code. The pattern that we’re suggested to use is of course async Task, but there are cases — like with Event Handlers in C# — where the method signatures...

Performance comparison between LinkedList and ToArray Some weeks ago I created an article comparing the performance of ToList versus ToArray when creating short lived collections that won’t be mutated, usually used to prevent multiple enumerations when iterating over a temporary LINQ transformation or to ensure mapping exceptions will be thrown...

Introduction Caching is a technique used to store frequently accessed data in a fast-access storage layer to improve application performance and reduce the load on backend systems. By serving data from the cache, we can avoid expensive database queries or API calls, resulting in faster response times and improved scalability....
