Tree structure vs composition

Trees are common in the application I currently develop. For example there is a tree of machines, where machine has a parent (machine family), the parent can have it's own parent and so on. Both machine and machine family can have parameters, these parameters are inherited from parents, so if a root parent has parameter A, the second parent has parameter B then machine will also contain parameters A and B. There is a lot of business logic attached to these parameters and the problem for me is 1) loading this whole tree structure from the database 2) iterating through parents for parameters. I started wondering, maybe composition will be a better approach. That means that instead of having parent, machine would have a list of parents with indexes (levels). So instead of this Machine A └── Parent 1...

Refresh token on Browser reload

I am trying to implement jwt authentication with refresh token logic for my school project. Refresh tokens are stored in browser HTTP cookies with CORs enabled. They are also stored in Mssql db (I'm thinking to change to redis) in server. My frontend is blazor WASM and my backend is Web API with FastEndpoints. Right now, I can't refresh the refresh token on browser reload. I have implement a refresh token refresh in frontend program.cs in the picture attached. But, that code is not being run everytime the browser refreshes. I have also attached the Jwt Authentication State Provider. Any suggestions are welcome as I am still learning on improving my code 🙂...

How can I improve my TestContainers with EF tests?

Hi, all: I've been trying to figure out my favorite way to implement test containers with Entity Framework contexts. I was running into an issue where my tests would persist their database changes between each testcase. To remedy this, I created a transactional test scope that rollsback the changes after each testcase. For this implementation, I have three files:...

Immediate.Validations conditional validators and delegates

Trying to reimplement some of my FluentValidation rules in IV and a lot of my rules depend on .When() and Must(). I see that AdditionalValidators is something I can define but the example in the docs makes it look like a lot of boilerplate in comparison

Creating API test suite

My team has an ASP.NET Core Web API. We are only two developers. The API is mature, and has hundreds of endpoints. We had to update our framework from .5 to .8, and now we have to test the API to make sure that migration doesn't break anything. We don't have any tests at the moment, so I am creating a test suite using Postman. Creating test scripts for every endpoint is taking forever, and I've only just started. I've resorted to just creating a smoke test of sorts that is just checking valid in...

ValueType disposable scope

Is there a safe way to use a value type to manage a disposable "scope"? For example in this code, it should write "1" to the console, but it actually writes "2" because it creates a copy of scope1 and disposes it: ```cs private static int disposeCount = 0; public ref struct Scope(object myObject) {...
