Interfaces can not contain any implementation  including default values   You need to switch to abstract class

You should use abstract class to initialize a property  You can t inititalize in Inteface

In the interface  you specify the property   public interface IResourcePolicy      string Version   get  set        In the implementing class  you need to implement it   public class ResourcePolicy   IResourcePolicy      public string Version   get  set        This looks similar  but it is something completely different  In the interface  there is no code  You just specify that there is a property with a getter and a setter  whatever they will do   In the class  you actually implement them  The shortest way to do this is using this   get  set    syntax  The compiler will create a field and generate the getter and setter implementation for it

You mean like this   class MyResourcePolicy   IResourcePolicy       private string version       public string Version           get               return this version                    set               this version   value
