У меня есть запрос, который работал нормально в ef core 2.2, пытаясь перейти к версии 3.1, и изменение запроса выдает мне следующую ошибку: «NavigationExpandingExpressionVisitor»
в обеих версиях: code: (это было работает нормально в 2.2
IQueryable<ReqestWithQA> fitReqests =
_context.Quetta
.Where(c => c.Category.CatName == getCategoryWsupId.CatName
&& c.OfferDate > DateTime.Now)
.Where(bb => !inList.Contains(bb.Id))
.GroupJoin(_context.quoteQuestions.OrderBy(a => a.QuoteId),
quetta => quetta.Id,
qestion => qestion.QuoteId, (quetta, joinQestionQuetta) => new ReqestWithQA
{
ReqText = quetta.ReqText,
Qentity = quetta.Qentity,
CatId = quetta.CatId,
CatName = quetta.Category.CatName,
District = quetta.District,
ApplicationDate = quetta.ApplicationDate,
DeliveryDate = quetta.DeliveryDate,
OfferDate = quetta.OfferDate,
TecnicalDetails = quetta.TecnicalDetails,
Bedget = quetta.Bedget,
Id = quetta.Id,
QAViewModel =
joinQestionQuetta
.Select(q => new QAViewModel
{
Question = q.Question,
Answers = q.Answers,
Id = q.QuoteId,
QuoteQuestionId = q.QuoteQuestionId
}).ToList()
});
это то, что я пробовал в 3.1 и получаю ту же ошибку MSG
IQueryable<ReqestWithQA> MyQ = from qu in _context.Quetta
join offers in _context.QuettaOffers on qu.Id equals offers.QuettaReqId into quoffers
join qa in _context.quoteQuestions on qu.Id equals qa.QuoteId into reqOffersQuestions
join the in _context.answers on qu.Id equals the.QuoteId into reqOffersQuAnswer
select new ReqestWithQA
{
ReqText = qu.ReqText,
Qentity = qu.Qentity,
CatId = qu.CatId,
CatName = qu.Category.CatName,
District = qu.District,
ApplicationDate = qu.ApplicationDate,
DeliveryDate = qu.DeliveryDate,
OfferDate = qu.OfferDate,
TecnicalDetails = qu.TecnicalDetails,
Bedget = qu.Bedget,
Id = qu.Id,
QAViewModel = reqOffersQuestions
.Select(q => new QAViewModel
{
