Я написал простой простой запрос, который работал раньше, когда я использовал .net core 2.2 (я использовал linq2db.EntityFrameworkCore )
projectContext.DocumentAnnotation.ToLinqToDBTable().InsertWithIdentity(() => new DocumentAnnotation { Name = name, ParentId = parentId }))
после обновления до .netcore 3.0 Я получаю ошибку ниже.
System.TypeLoadException
HResult=0x80131522

Мой класс DocumentAnnotation такой же, как и ниже.
public partial class DocumentAnnotation
{
public DocumentAnnotation()
{
DocumentAnnotationValue = new HashSet<DocumentAnnotationValue>();
DocumentAnnotationValueMultiPage = new HashSet<DocumentAnnotationValueMultiPage>();
ChildDocumentAnnotation = new HashSet<DocumentAnnotation>();
}
public int Id { get; set; }
public string Name { get; set; }
public int? ParentId { get; set; }
public bool? IsMultiPage { get; set; }
public virtual DocumentAnnotation Parent { get; set; }
public virtual ICollection<DocumentAnnotationValue> DocumentAnnotationValue { get; set; }
public virtual ICollection<DocumentAnnotationValueMultiPage> DocumentAnnotationValueMultiPage { get; set; }
public virtual ICollection<DocumentAnnotation> ChildDocumentAnnotation { get; set; }
}
