title: Does not implement interface member issues
body: <p>I have:</p>
  
  <pre><code>public interface ITest
  {
      string test { get; set; }
  }
  </code></pre>
  
  <p>And</p>
  
  <pre><code>[DataContract]
  public class TestGeneric : ITest
  {
      [DataMember]
      public string test;
  }
  </code></pre>
  
  <p>But i keep getting the error: <code>'TestGeneric' does not implement interface member 'ITest.Test'</code> on <code>TestGeneric</code> in the <code>public class TestGeneric : ITest</code> line of code. Would someone be able to explain why this is?</p>
