How to implement alternative items. A is alt. to B and C => B alt. to A and C, etc.
How is this usually designed? An item with alternative items. For example B is alternative to A. That means A is alternative to B too. If I create C alternative to A, A and B become alternatives to C. Each one is an alternative to each other.
Now imagine you have a tab for each (A, B, C) where you have the rows of alternatives.
A Sync service has to update each tab when an alternative is added anywhere in the tabs.
How would you implement this at the db or object level?

Is using a blazor component from a service a good idea?
I have a DocumentManagerComponent.razor that is used in multiple places across the app. It has an OnDelete EventCallback that is used for marking a row as deleted and in other places to directly delete a row from database. That depends of the type of page where the component is used, the event it used with different methods.
The lead developer asked to remove this component from everywhere, place it in MainLayout, hook it up with a service (DocumentManagerService) and use this service to manage documents: open, view, edit, delete.
Is this a good idea? Do you see any issues that would result from this?
The initial goal was to have less code for implementing the component but now with a service, it doesn't look as having less code. In fact, moving the delete logic inside the service creates issues with the component not accepting different settings once initially set for a use case, probably because the same instance used for one page can't adapt well to another page where the service is used.
This lead me to subscribe to an event placed inside the service and do the delete logic outside of the service.
I looked around and I couldn't find any example of using a component as a service.

❔ Inheritance Tricky Question
If ListPage and DetailPage have TitlebarButtons but also other buttons outside of the titlebar... than ListPageButtonSettings and DetailPageButtonSettings should inherit TitlebarButtonSettings or TitlebarButtonSettings should be a property inside of ListPageButtonSettings and DetailPageButtonSettings?
Someone told me that a class should not inherit another class if the parent class is not of the same nature, like in my case, ListPageButtonSettings is not a TitlebarButtonSettings and it contains other button settings not related to titlebar.

❔ What’s the point of Database.BeginTransaction?
I’m trying to wrap my head around it, what is the main reason for using BeginTransaction?
Is it because we want to make sure that both Save transactions are done successful before Commit or is because you have to make sure Disposing will rollback the first transaction i.e. out of two transaction?
I find Disposing not Rollingback in time my transaction if I refresh the page.
The class that has the logic of transactions should be Disposable also or just using a “using” block is enough?
Thank you!

Inconsistent namespaces
(Solved) I'm currently working on a solution with a lot of subfolders and I noticed that the namespaces of .cs files are not reflecting the folder structure.
On top of that, in some projects, i.e. the files inside "Commands" and "Queries" have the same namespace and in other projects they have wrong namespace like ending in "Messages" while the folder name is Queries.
I would be able to fix this automatically in Rider by naming all namespaces according to folder structure but I'm afraid I will end up having hundreds of 10 levels long namespaces and usings.
Other solution is to go in every file and understand the pattern that was used in naming the namespaces and correct the wrong ones (this will take a lot of time).
