Ensuring Santa’s success with automated tests

I’m a big fan of automated testing, but I know that many developers in the C# space are still getting used to some of the concepts, so I figured we’d take this time to do a gentler introduction to test automation with a slightly contrived scenario, and solve it using NUnit and xUnit.

Async Disposables the easy way

In the System.Reactive.Disposables namespace (part of Reactive Extensions), there’s a small and useful Disposable class. It has a Create method that takes in an Action and returns an IDisposable instance. When that instance is disposed, the action is called. It’s a nice way of creating an ad-hoc IDisposable.

Digging into the .NET Dictionary implementation

I had dug into the implementation of the .NET dictionary because of this issue. More specifically, I wanted to know what kind of collision handling system is in use there. The two common ones are open addressing and chaining. The code for the Dictionary is available, but I don’t think that I read much about how it works. I found some interesting tidbits about how it works, enough to warrant a post to remember it for the future.
