.NET: how to consume a scoped service from a singleton?
This is a short post about a very specific C#/.NET topic. They say one needs to pick their battles. Here I decided to pick a battle with a StackOverflow answer from 2018 and a couple of fellow tech bloggers, because I have opinions. This is not exactly a tutorial, so I assume the reader has some basic understanding of .NET, its DI mechanisms and service lifetimes. Q: In .NET, how to consume a…
A common challenge in .NET programming is consuming a scoped service from a singleton. Microsoft's documentation discourages the usage of the Service Locator pattern. The typical solution involves creating a scope on demand using IServiceScopeFactory. However, this approach still carries the disadvantages of the Service Locator pattern.
To address this issue, the author proposes creating a thin wrapper, MyWrappedScoped, that allows scoped services to act like singletons. MyWrappedScoped takes an IServiceScopeFactory in its constructor and provides a Forward method to seamlessly call scoped service methods as if they were singleton methods. This approach avoids the pitfalls of the Service Locator pattern while maintaining the desired functionality.
