Not sure if the code below should be considered a hack, but the easiest way of removing the AspNet prefix is to iterate through the models.

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    foreach (var entityType in modelBuilder.Model.GetEntityTypes())
    {
        var table = entityType.Relational().TableName;
        if (table.StartsWith("AspNet")) {
            entityType.Relational().TableName = table.Substring(6);
        }
    };
}

Found the initial code in a 2014 asp net issue and since copy paste didn’t cut it, did a quick update of the method / property names.

This also allows you to replace it with whatever else you want, or add a generic table prefix.
