Back word compatible with new added member

Question

I am adding a new data member in a class which is part of shared nuget package. On Server application, I need to support both nuget packages, previous nuget package member does not have newly added member. How do I map this member so my code does not break. Please review following code.

Nuget Package 1.0


Class Employee
{
   public int Id {get; set;}
   public string Address { get; set;}
}

Nuget Package 1.1


Class Employee
{
   public int Id {get; set;}
   public string Address { get; set;}
   public string Department { get; set;}
}

From the client, if Department member is not passed I want to set server Department to Null else set the value passed by client.

Create Employee Partial class and add Department prop in that class — Mannan Bahelim, May 15 '19 at 05:02
Client is currently using Nuget Package 1.0, so department is not used in current code, but they will consume this property in future. — Nainesh Patel, May 15 '19 at 17:27

Although I'm not sure I fully understand the issue I believe what your looking for may be auto-property initializers:

class Employee
{
  public int Id {get; set;}
  public string Address { get; set;}
 public string Department { get; set;} = null;
}
