❔ How to use Database First Approach with asp.net Identity?

Does anyone have experience doing this? Do you have any recommended steps one should follow when doing something like this? When I reverse scaffold, it seems to also create models for my asp.net identity tables. Should I be deleting those?

✅ best LINQ method to sort after subtracting two properties?

I have a list of objects with two fields, num1 and num2. I would like to subtract num1 by num2 and then sort descending by the resulting value. Can anyone recommend a LINQ method for this?

❔ Registering a User with Identity and EfCore calls the OnConfiguring Method of my AppDbContext?

Is this supposed to be happening? It seems incredibly inefficient if so. I have attached an animated gif to show what I mean. https://media.discordapp.net/attachments/1043638776200695870/1043638776410415144/Animation.gif

❔ Changing object property not limited to scope?

So here in UserManager there is a method:

public virtual async Task UpdateNormalizedUserNameAsync(TUser user)
    {
        var normalizedName = NormalizeName(await GetUserNameAsync(user).ConfigureAwait(false));
        normalizedName = ProtectPersonalData(normalizedName);
        await Store.SetNormalizedUserNameAsync(user, normalizedName, CancellationToken).ConfigureAwait(false);
    }

public virtual async Task UpdateNormalizedUserNameAsync(TUser user)
    {
        var normalizedName = NormalizeName(await GetUserNameAsync(user).ConfigureAwait(false));
        normalizedName = ProtectPersonalData(normalizedName);
        await Store.SetNormalizedUserNameAsync(user, normalizedName, CancellationToken).ConfigureAwait(false);
    }

And then in the Store.SetNormalizedUserNamyAsync method:

public virtual Task SetNormalizedUserNameAsync(TUser user, string? normalizedName, CancellationToken cancellationToken = default(CancellationToken))
    {
        cancellationToken.ThrowIfCancellationRequested();
        ThrowIfDisposed();
        if (user == null)
        {
            throw new ArgumentNullException(nameof(user));
        }
        user.NormalizedUserName = normalizedName;
        return Task.CompletedTask;
    }

public virtual Task SetNormalizedUserNameAsync(TUser user, string? normalizedName, CancellationToken cancellationToken = default(CancellationToken))
    {
        cancellationToken.ThrowIfCancellationRequested();
        ThrowIfDisposed();
        if (user == null)
        {
            throw new ArgumentNullException(nameof(user));
        }
        user.NormalizedUserName = normalizedName;
        return Task.CompletedTask;
    }

There is no ref keyword before TUser. So doesn't that mean setting the user.NormalizedUserName is useless since the change will not be affected by whatever calls it?
