Tracking down references to a service
<p>I get this error in my ASP.NET 3.5 website:</p>

<p>Error   3 Cannot update project reference 'Services'. Source project not available. </p>

<p>How can I track down any reference to this assembly so I can then delete it? It must be called from somewhere. I no longer have an assembly in my project with this name.</p>

<p>Thanks</p>
