Code Maze·2yWhat Does the null! Statement Do?
The null! statement in C# is used to suppress the CS8618 warning, which indicates that a non-nullable reference type property might be null. By attaching the null-forgiving operator (!) to null, it marks a nullable type as non-nullable, bypassing compiler warnings. While useful for certain scenarios, developers should use it sparingly as it doesn't prevent runtime NullReferenceExceptions.

Waseem .NET Newsletter·2yEP 64 : Service Locator Pattern in .NET
The service locator pattern in .NET allows for the injection and retrieval of services via a central service provider. It's useful in scenarios where dependency injection isn't feasible, such as dealing with service scope mismatches or updating legacy code. Although practical, it has drawbacks, including testing complications and potential for poor design choices. Direct dependency injection is generally preferred for its cleaner and more manageable structure.
