将 .netcore 2.1 升级到 .net 6 - Linq 查询翻译错误

Question

我有两个两个查询。 第一个是这样的。

var studentCourses = _context.StudentAcademicPathCourses
    .Include(x => x.Course)
    .Where(x => x.StudentAcademicPathId == studentAcademicPath.Id)
    .Select(apc => new
    {
        apc.AcademicPathSectionId,
        apc.CourseDerivation,

        Course = new
        {
            apc.Course.EctsCredits,
        },

        StudentCourseSection = apc.StudentCourseSection == null
                                || false == validStudentCourseSectionIds.Contains(apc.StudentCourseSectionId)
            ? null
            : new
            {
                apc.StudentCourseSection.Ects,
            },
    })
    .ToList();

第二个是

var result = _context.StudentAcademicPaths
    .Where(x => x.Id == studentAcademicPath.Id
                && x.TenantId == GetRequestUserTenantId())
    .Select(sap => new
    {
        AcademicPath = new
        {
            Sections = sap.AcademicPath.AcademicPathSections.Select(sec => new AcademicPathAPI_Section
            {
                CompletedECTS = studentCourses
                    .Where(x => x.AcademicPathSectionId == sec.Id
                        &&
                        (
                            x.CourseDerivation == AcademicPathCourseDerivation.Transferred
                            ||
                            (
                                x.StudentCourseSection != null
                                && true == x.StudentCourseSection.IsPassed
                            )
                        )
                    )
                    .Sum(x => x.Course.EctsCredits),

            })
            .OrderBy(x => x.Code)
            .ToList(),
        },
    }).First();

当 studentCourses 完成时，结果正在运行，但 CompletedECTS 给出了这样的错误

“LINQ 表达式 'a => a.AcademicPathSectionId == EntityShaperExpression: EvolveAPI.Models.AcademicPathSection ValueBufferExpression: ProjectionBindingExpression: EmptyProjectionMember IsNullable: False.Id' 无法翻译。要么以可翻译的形式重写查询，要么切换通过插入对 'AsEnumerable'、'AsAsyncEnumerable'、'ToList' 或 'ToListAsync' 的调用来显式地进行客户端评估。” 将框架升级到 .netcore 2.1 到 .net6 后出现此错误
