Hi, This is actually not related to the asp.netzero. But hope you can give a better solution for me with your vast experience.
public List<PropertyListDto> GetPropertiesByStatus(GetPropertyInput input)
{
//exception occurs here
var properties = _propertyRepository
.GetAll()
.Include(p => p.Address)
.ToList();
var results = new List<PropertyListDto>(properties.OrderBy(p => p.Id).MapTo<List<PropertyListDto>>());
return results;
}
[AutoMapFrom(typeof(Property))]
public class PropertyListDto : FullAuditedEntityDto
{
public new int Id { get; set; }
public CountyListDto County { get; set; }
public string Priority { get; set; }
public string Dist { get; set; }
public decimal ListingPrice { get; set; }
public string Blk { get; set; }
public AddressDto Address { get; set; }
public string Contact { get; set; }
public string Lot { get; set; }
public decimal Taxes { get; set; }
public string Mls { get; set; }
public ICollection<CommentEditDto> Comments { get; set; }
public int? LegacyId { get; set; }
}

When I use .AsNoTracking(), then it works fine on the first query.
var properties = _propertyRepository .GetAll() .AsNoTracking() .Include(p => p.Address) .ToList();But then the problem is on MapTo line.Could you tell me how to sort it out ? Thanks.
var results = new List<PropertyListDto>(properties.OrderBy(p => p.Id).MapTo<List<PropertyListDto>>());This is the error :

Hi,
I haven't seen timeout eror for automapper before. It's very strange. Probably, it's not related to automapper. Can you share the stacktrace? Also, you can try to increase UOW timeout. Add this property to your app service method:
[UnitOfWork(timeout: 360000)]
