Does lambda event subscription create memory leak?
<p>Does this code create a memory leak?</p>

<pre><code>WebClient client = new WebClient();

client.DownloadDataCompleted += (sen, args) =&gt; {

};
client.DownloadData("http://foo.bar");
</code></pre>

<p>As there is no way to actually unsubscribe from the event. Can I say we must never use lambda for event subscription?</p>
