title: Why can't I use SynchronizedCollection when I include System.Collections.Generic?
body: <p>I'm trying to include the following line in my C# code, but for some reason it's being marked as an error:</p>
  
  <pre><code>        public SynchronizedCollection&lt;Uri&gt; allImages = new SynchronizedCollection&lt;Uri&gt;();
  </code></pre>
  
  <p>I've tried including <code>using System.Collections.Generic</code> but it does not resolve the issue. Any idea how I can get a <code>SynchronizedCollection&lt;T&gt;</code> working in my application?</p>
