Inheritance or composition

This is going to be a long one, totally get it if nobody makes it to the end 😅 I'm writing an open-source library for writing durable workflows, similar in principle to Azure Durable Functions, where you can write persistent workflows using async/await. However, unlike Durable Functions, my library introduces a dedicated awaitable type called DTask. Because DTask requires infrastructural support, you can't just await one inside a regular async method. To run them, providers must implement its infrastructure components (for storage access, serialization, etc.). One of these components is called DAsyncHost and, as of today, is an abstract class: it exposes and implements some methods to interact with these durable tasks (StartAsync, ResumeAsync), but also defines several abstract callbacks that implementations must override. For example, OnDelayAsync determines how to handle DTask.Delay, OnSucceedAsync defines what to do when a durable task completes. Link to the class: https://github.com/gianvitodifilippo/DTasks/blob/main/src/DTasks/Infrastructure/DAsyncHost.cs I went with an abstract class so I could provide virtual methods with default implementations and add new features in the future without breaking existing implementations (thanks to virtuals). However, I'm not a big fan of abstract classes and I usually prefer composition over inheritance, and I’m starting to wonder if DAsyncHost should have been a concrete class that could instead be injected into those classes that today are its child classes. I'm struggling now even more because I want to add a new overload of the StartAsync method that allows callers to pass a context object that the host can access during the whole execution. To do so, I thought of adding a type parameter to the type (DAsyncHost<TContext>) and a new StartAsync(TContext context, ...) method, but this started to feel like a smell to me....

✅ Beginner Projects

Hi everyone, I'm just starting out on my journey with C#, and I had a question about building Windows apps. I'm still pretty early in the learning process — so far, I've made a Tic-Tac-Toe game and a To-Do list app, both in the console. Now I'm thinking about creating a simple expense/budget app, but I'd like to make it look and feel like a real app (with a GUI). I'm wondering: is it too early for me to start exploring this, or should I stick with console projects for a bit longer?...

Is it possible to reverse a string letter by letter using only regular expression?

I am learning string manipulation. Learned a bit about string and StringBuilder. Now onto Regex and I'm trying to do everything which I do with string methods and StringBuilder methods by using Regex alone for learning purposes. But reversing a string letter by letter seems pretty hard by just Regex.Replace(intialString, pattern, replacement) I guess pattern can be:...

How to get .NET framework 4.8.1 installed on IIS Web Server running Windows Server 2019 via choco?

Set an environment variable as part of a Visual Studio multi-project startup config

I have a solution with 2 main startup configs, V3 and V4, each with a good few API projects. Each of these projects reads environment variables from a text file at startup, but for the V3 config they must read one text file, and for the V4 config the must read another text file. Right now each time I switch configs, I have to go and edit the environment variable loader to use the correct file, and this is very easy to forget, so I am trying to find a way to use the startup config to determine which variable file gets read. The best I've been able to come up with so var is adding a little console app to the solution, and to both startup configs. In the V3 config the console app starts up with a V3_Environment launchsettings profile, which sets a DEBUG_ENV_VAR_FILE environment variable, and for the V4 startup, the same console app starts up with a V3_Environment launchsettings profile, setting the same variable to a different value. Then the environment variable loader uses this variable to determine which file to load the variables from....

Updating SecurityStamp on Many users

Using .net 9 with Entity Framework Identity, i often feel very locked in to getting a user from the DB. In this case i have a need to logout alot of users if changes are made to a group they are a part of. I would usually call UserManager.UpdateSecurityStamp, but the i would have to get and track each user from the database, just to update that one. I've found the implementation to generate a SecurityStamp but it doesn't feel right to copy that into a new class. What i would like to do is use Ex...

Maybe the case for object pooling?

I have a large array I am processing. Each item is a large object that has multiple processors (classes with state). Creating those 10 for example proccessors for every item in the list will be expensive. Should I use something like object pooling? So I create the processor once and reuse it using a reset pattern? What's the best way to handle it? Also maybe there is a better alternative to classes altogethe?...
