✅ Disposing dbContext with dependency injection
Hi!
I am developing an Avalonia UI app. I am displaying there some data, which is stored in the sqlite database. The data - rows in that matter - can be deleted or added, but once they are there - they are not modified (at least for now ;)).
I have a factory which gets data from db and then creates a view model passing there the data (and few other things). The factory itself I've registered in service container as a singleton and dbContext as a transient. dbContext is injected into the factory. As I am not tracking entities changes and not adding or deleting data in that place, I've configured the context with
I have not encountered any issues so far, however I am concerned about proper dbContext disposing. If a factory is singleton, even when dbContext is transient, once it's injected is still there, right? The view model can be created few times during app lifetime, rows can be added/removed in the meantime.
Can I leave it as it is or should I do smth about it? Eg. instead of injecting dbContext itself I can create and inject another factory which will instantiate dbContext via constructor each time needed, or maybe you can suggest other solutions?
Any help appreciated
