title: Read Config Value in MSBuild Task
body: <p>Is there a way to read a System.Config connection string in an MSBuild task?</p>
  
  <p>Basically I have my connection string setup in a config file</p>
  
  <pre><code>&lt;add name="MyApp.MyConnectionString" connectionString="..." /&gt;
  </code></pre>
  
  <p>And I would like to reference it in an MSBuild task like so ...</p>
  
  <pre><code>&lt;Target Name="Migrate" DependsOnTargets="Build"&gt;
      ...
      &lt;Migrate Connectionstring="$(MyApp.MyConnectionString)" ... /&gt;
  &lt;/Target&gt;
  </code></pre>
