Entity Framework Include Issue

Question

I am currently working on a Customer Repository and I came across this issue of the include functionality not working. I was hoping that someone might be able to shed some light on why this isn't working and maybe give some feedback on how to implement this better.

public IQueryable<Domain.Customers.Customer> GetCustomers(params Expression<Func<Domain.Customers.Customer, object>>[] include)
{
        IQueryable<Domain.Customers.Customer> query = _context.Customers.AsNoTracking();
        foreach (var property in include)
        {
            query.Include(property);
        }
        return query;
}

A call to this function looks like this

var customer = _customerRepository.GetCustomers(p=>p.Category);

Any help would be greatly appreciated.

All LINQ statements return new IQueryable<T> / IEnumerable<T> instances. You have to keep the latest modification:

query = query.Include(property);
