title: Roslyn Solution Refresh
body: <p>I am creating some VSIX. I have VisualStudioWorkspace service. Now, I am able to parse the syntax tree and it all works just fine. But, when a new file is added to the solution (for example as a result of some VisualStudio work), this document is not present in VisualStudioWorkspace.CurrentSolution. It works like that:</p>
  <p>First, I get the workspace:</p>
  <pre><code>currentWorkspace = componentModel.GetService&lt;VisualStudioWorkspace&gt;();
  </code></pre>
  <p>Now in <code>currentWorkspace.CurrentSolution</code> I am able to get the syntaxt tree. Now a s the result of some work, a new cs file is added to the solution, but <code>currentWorkspace.CurrentSolution</code> does not show it. Do I have to to add it manually? Is there any way to refresh this CurrentSolution object?</p>
