Property name in a type must be unique

Question

I am using Entity Framework 5 and I have the following entities:

public class User {
  public Int32 Id { get; set; }
  public String Username { get; set; }    
          


        

Answer 1

This may happen also when there is a mismatch in the type of the referencing property. For example:

public string TipId { get; set; }

instead of

public int TipId { get; set; }
