entity-frameworkinterfaceentityef-core-3.0explicit-interface

When using Explicit Interface Implementation in Entity classes , EF Core does not creates column in table


public interface IRecordInformation
    {
         DateTime CreatedOn { get; set; }
         DateTime ModifiedOn { get; set; }

    }
public class CareerApplication : IRecordInformation
    {
        public int CareerApplicationId { get; set; }
        public string Name { get; set; }
        public string FileName { get; set; }
        public string Email { get; set; }
        public DateTime IRecordInformation.CreatedOn { get; set; }
        public  DateTime IRecordInformation.ModifiedOn { get; set; }
    }

Why i am doing this ? Because if i change the interface and remove a property then there should be compile time error that there is no property declared in interface for which the implementation exist in class . This way i can remove the implementation from class . But if i dont use explicit implementation using interface name in class then if i remove a property from interface then that corresponding property will be treated as the property of class itself.

I have tried doing like

public DateTime CreatedOn { get => ((IRecordInformation)this).CreatedOn; set => ((IRecordInformation)this).CreatedOn = value; }

But there is a stack overflow exception for which i am attaching the image

Error i am facing


Solution

  • It works as suggested by @Gert Arnold

    public DateTime CreatedOn { get => ((IRecordInformation)this).CreatedOn; set => ((IRecordInformation)this).CreatedOn = value; }
            public DateTime ModifiedOn
            {
                get
                {
                    return ((IRecordInformation)this).ModifiedOn;
                }
                set
                {
                    ((IRecordInformation)this).ModifiedOn = value;
                }
    
            }
            DateTime IRecordInformation.CreatedOn { get; set; }
            DateTime IRecordInformation.ModifiedOn { get; set; }
    
            public bool IsPublished
            {
                get
                {
                    return ((IPublishInformation)this).IsPublished;
                }
                set
                {
                    ((IPublishInformation)this).IsPublished = value;
                }
    
            }
            bool IPublishInformation.IsPublished { get; set; }
