在控制台应用程序中使用Microsoft.EntityFrameworkCore 2.1.4检索XmlSerialization数据时，我发现以下LINQ查询非常慢，并且需要近7分钟才能完成：
var fullSubmission = context.CYP000
.Include(p => p.CYP001)
.ThenInclude(p => p.CYP002)
.Include(p => p.CYP001)
.ThenInclude(p => p.CYP101)
.ThenInclude(r => r.CYP201)
.ThenInclude(c => c.CYP202)
.Single(x => x.SubmissionId == submissionId);
24/10/2018 14:50:37 - Retrieved full submission in 00:06:46.8583712
如果我分两步这样做以获得等效结果，则总时间少于30秒：
var submission = context.CYP000
.Single(s => s.SubmissionId == submissionId);
var patients = context.CYP001
.Include(p => p.CYP101)
.ThenInclude(r => r.CYP201)
.ThenInclude(c => c.CYP202)
.Include(p => p.CYP002)
.Where(p => p.SubmissionId == submissionId)
.ToList();
submission.CYP001 = patients;
24/10/2018 14:43:29 - Retrieved submission in 00:00:01.1036359
24/10/2018 14:43:50 - Retrieved patients in 00:00:21.0496461
我没有发现我的DbContext或类有任何问题，并且数据库中有足够的索引，是什么导致执行缓慢？
这是使用单个LINQ查询时的日志：
