I am using the following:
- EntityFrameworkCore 3.1.2
- .Net Standard Library 2.1
- Automapper 9.0.0
- Automapper.Extension.Microsoft.DependencyInjection 7.0.0
My DI for AutoMapper looks like this:
services.AddAutoMapper(Assembly.GetExecutingAssembly());
I have an IMapFrom with default implementation:
using AutoMapper;
namespace Application.Common.Mappings
{
public interface IMapFrom<T>
{
void Mapping(Profile profile) => profile.CreateMap(typeof(T), GetType());
}
}
I have a DTO class as follows:
public class ServiceRegistrationDto : IMapFrom<ServiceRegistration>
{
public string ServiceName { get; set; }
public string MessageType { get; set; }
public string ServiceURL { get; set; }
public void Mapping(Profile profile)
{
profile.CreateMap<ServiceRegistration, ServiceRegistrationDto>();
}
}
In my Handler I am doing the following:
public async Task<ServiceRegistrationViewModel> Handle(GetServiceRegistrationListQuery request, CancellationToken cancellationToken)
{
var serviceRegistrations = await _context.ServiceRegistrations
.Where(s => s.MessageType.Equals(request.MessageType, StringComparison.InvariantCultureIgnoreCase))
.ProjectTo<ServiceRegistrationDto>(_mapper.ConfigurationProvider)
.ToListAsync(cancellationToken);
return null;
}
The issue is that the "ProjectTo" is not a definition of IQueryable. I was under the impression that Automapper had Queryable Extensions. Am I missing a NuGet Package? I am following examples from Northwind Traders and I can't figure out what I have different.
I can get to "ProjectTo" using IMapper like this:
var x = _mapper.ProjectTo<ServiceRegistrationDto>(serviceRegistrations);
But I would prefer to do it as part of the IQueryable like you should be able to.
