title: NUnit Test Properties no longer supports Add?
body: <p>In previous versions of nunit.framework (e.g. 3.7.1.0), you could add properties to <code>TestContext.Test</code>  Like this in C#:</p>
  
  <p><code>TestContext.CurrentContext.Test.Properties.Add("NewProperty", "some value");
  </code></p>
  
  <p>I updated to a newer version (e.g. 3.10.1), and that is no longer an option?  </p>
  
  <p>I used to pack it with extra information about the test run during runtime. And then when my base class [TearDown] method ran, I would do extra processing for those properties.</p>
  
  <p>Has that moved and/or is there another way to do that?  </p>
