❔ Singleton/semaphor EF Core
I need to make sure only one instance of EF Core (db context) runs at once, otherwise if two requests arrive at the same time, they'll both search for the username in the DB, see that they don't exist and try to create them, instead of redirecting the second request to a login logic.
How can something like this be accomplished? There's a billion different ways to implement this and I'm not entirely sure which one is the best/simplest for my use case. There's blocking collection, dictionaries, semaphores, semaphoreSlim, queues, concurrentqueues, list goes on.
