title: Interfaces and Versioning
body: <p>I am designing a new System and I have a lot of Interfaces that will grow over time with the system. What is the best practice to name this interfaces</p>
  
  <pre><code>ISomethingV01
  ISomethingV02
  etc
  </code></pre>
  
  <p>and I do this</p>
  
  <pre><code>public interface ISomething{
        void method();
  }
  </code></pre>
  
  <p>then I have to add method 2 so now what I do?</p>
  
  <pre><code>public interface ISomethingV2:ISomething{
        void method2();
  }
  </code></pre>
  
  <p>or same other way?</p>
