Use Custom Attributes with ASP.NET Identity
So recently i got into ASP.NET Identity with all the auth stuff so i can write more robust backend software
But now i have a question, the way id like to handle permissions for users is by enabling scopes on them for example
account.manage or profile.view for example, now in my backend id like to have have a middleware/attribute like [RequireScope("account.manage")] which uses the Authenticated user to see its scopes
so now i have 2 questions
1. is it even a good idea to do it like that, if no what are my alternatives?
2. how can i implement this properly20 replies
Question about GraphQL
I'm working on a fairly large (mobile app) project with a friend
The app itself is written in Kotlin and our backend service is written in C# using ASP.NET, we use EF Core to interact with our database, my friend has made a suggestion that we could use GraphQL for the backend service, now while I see the advantages that GQL could bring to the table I also see other things:
- lots of issues that GraphQL is supposed to solve feel like are already easily done with our EF Core structure or the Model structure in general
- users being able to request the data they Want sounds like a nightmare to me
- single endpoint for a project this large may serve lots of disadvantages over time specially since we'd basically throw out the whole API controller thing where we can easily manage what class does what
What do you guys think

How does API versioning work
I wanted to ask for API versioning works and how to properly implement it into ASP.NET
because to me api/v1 and api/v2 just seem like 2 controllers that basically have the same controllers just handled differently
Is there a proper way to set this up and if yes, what's the best approach for it and how to handle a version like V1 going out if support if for example V5 rolls around

What is dependency injection and when should I realistically use it
Recently I've got some critics from people saying I should not create a Helper / Utils class with a bunch of public static methods and that I should rather use DI practices for it
For me my approach makes sense since my Utils are only supposed to exist once in the whole program so I can access it from everywhere
So what exactly is bad about my approach?

Avalonia ViewLocator not ViewLocating
I have an Avalonia project with multiple pages like MainView and LoginView and SettingsView etc, pretty standard stuff
But now I have the following problem, trying to set my
ViewModelBase.ContentViewModel to something will result in the ContentViewModel being null for no apparent reason
The program workflow goes like this:
The program starts -> the program sets the DataContext to new MainViewModel() -> MainViewModel checks if the user is logged in to an account, if not it will set ContentViewModel to new LoginViewModel(), in the LoginView the user is supposed to log into an account which is then supposed to set the ContentViewModel to a new MainViewModel(), but instead the ContentViewModel is null9 replies
✅ Help with Avalonia databinding and library objects on ViewModels
Lets say I have an API Client that allows me to fetch data like chats, messages etc
That API Client responds with a List of the object which i use to construct my component (in this case for example a chat with a simple name, user icon and last message sent in it)
Now i bind the
<ItemsControl> to my List of fetched chats and set the datatemplate to my Chat component
But now in my ViewModel class for said Chat i need to access the current chat that is being used to construct my View (the chat component) so i can further manipulate and process it87 replies

Question about Avalonia
So im a beginner in Avalonia and im watching a youtube tutorial series (more specifically this tutorial) and i have a question about the Community MVVM Toolkit
In my Main view im creating a SplitView with a property
IsPaneOpen which has a Binding to a value called isPaneOpen, however, in my code i have a private bool _isPaneOpen = false; which has an [ObservableProperty] Attribute to it
How does Avalonia know that _isPaneOpen is my binding to isPaneOpen, the same question goes for how avalonia knows that my OnButtonClick() with my [RelayCommand] attribute is the same function as my binding OnButtonClickCommand()
Its a very beginner question but i wonder how Avalonia / the MVVM tookit knows what members im reffering to even tho they dont have the same name4 replies
✅ How to learn XAML styling
I'm new to XAML styling in C# using WinUI 3 (id use MAUI but since I mainly focus on Windows Desktop it's overkill), coming from Kotlin Jetpack compose (for mobile apps) I have cool concepts in mind for my design and know the rough way to get there but somehow nothing works out like it's supposed to do and it's my lack of understanding how XAML styling works properly
This is purely about design and not about things such as Data binding etc
Also my next question is if WinUI / XAML styling has some sort of creating components that I can just Re use

How does database sharding work
I understand the concept of load balancing where for example Service.myApi redirects the request to a server like s1, s2, etc.myApi or even media servers that balance the media into mulitple servers like media.myapi -> m3.myApi
But in the case of the media server the data where a media file is stored, is stored in the database so it's just a matter of asking the database for such data
But then how can I know what database is targeted when there is db.myapi which would have db1.myApi and db2.myApi since I can't just ask the database for data without knowing where it's stored

How to set env variables in Docker reliably
I want to deploy my backend (or really all my programs) using Kubernetes / CircleCI and now im facing the issue of wanting to have my credentials and such set as environment variables for my Image on deploy
My current structure is something like: program starts -> generates config files -> reads config files
Now with the config files being waited for to get filled in it kinda destroys the point of automatic deployment, and me using SQLite as database doesnt help either considering it would be gone each time
TLDR;
So how can i reliably pass Environment variables for credentials like that into my Image on deploy
