Discover how to handle concurrent collection iteration with snapshots, implement health checks in ASP.NET Core, and understand FrozenDictionary performance improvements in .NET 8.

Enumerating concurrent collections with snapshots in C#

3 minutes by Tore Aurstad

Concurrent collections let you add or remove items while looping, unlike regular C# collections that throw errors. To get a stable snapshot during iteration, you can use ToArray(), but it’s expensive because it locks and copies the whole collection.
