New System.Collections.Frozen namespace in .NET 8

The .NET 8 release introduces a new namespace, System.Collections.Frozen, which provides two new immutable collection types: FrozenDictionary<TKey, TValue> and FrozenSet<T> These types are designed for scenarios where collections are created infrequently but are used frequently at runtime. They offer excellent lookup performance and are ideal for cases where a collection is created once, potentially at the startup of an application, and is used throughout the remainder of the life of the application. Benefits of using frozen collections Examples of using frozen collections Example 1: Using FrozenDictionary to store configuration data In this example, the configuration variable is a FrozenDictionary that…

Do not resolve dependencies manually in ASP.NET Core Unit Testing

Dependency Injection (DI) is a core concept in ASP.NET Core, and it’s not just for production code. You should also leverage DI in your unit tests. Instead of manually resolving dependencies, using ServiceCollection to handle this is the recommended way. In this blog post, we’ll delve into why you should avoid manually resolving dependencies in unit testing and how to utilize ServiceCollection for a cleaner and more maintainable testing setup. The Pitfall of Manual Dependency Resolution Before we explore the right way to handle dependencies in unit tests, let’s discuss a common pitfall: manually resolving dependencies. I’ve seen people manually…
