Question

As far as I am aware, for the property to be saved in the database it cannot be ReadOnly.
IIdentity properties: AuthenticationType, IsAuthenticated and Name are all ReadOnly.

Is making the wrapper to the properties that need to be saved the only solution or there are better ones?

EDIT:
I might not have explained my question that well. Here is the sample code for one of the ReadOnly properties, I have added UserName property for the Entity Framework:

Public Property UserName As String
    Get
        Return _userName 
    End Get
    Private Set(value As String)
        userName = value
    End Set

Public ReadOnly Property Name As String Implements System.Security.Principal.IIdentity.Name
    Get
        Return UserName
    End Get
End Property

What I wanted to ask is if there is any better way of doing it.

Answer 1

IIdentity properties are read only but the implementation can have setters. If you are using EDMX for mapping you don’t have to expose these setters as public.

Edit:

This is possible in C# so hopefully you can use similar approach with VB.NET (I can only read VB code, not write):

public interface ITest {
    string Name { get; }
}

public class Test : ITest {
    public string Name { get; set; }
}

The class offers setter even the interface didn’t define it.
