There is a ready to use solution at URF - Unit of Work & (extensible/generic) Repositories Framework. It will save you a lot of time. They implemented a generic repository (also there is an async repository). For extending any repository they have used extensions like this:

     public static decimal GetCustomerOrderTotalByYear(this IRepository repository, string customerId, int year)
    {
        return repository
            .Queryable()
            .Where(c => c.CustomerID == customerId)
            .SelectMany(c => c.Orders.Where(o => o.OrderDate != null && o.OrderDate.Value.Year == year))
            .SelectMany(c => c.OrderDetails)
            .Select(c => c.Quantity*c.UnitPrice)
            .Sum();
    }

Some classes like QueryObject may be an overwork depending on your project but overally it is good solution to help you get up and running.
