title: problems with Reporting Services 2005 to .NET 4 framework on web server
body: <p>We have had custom ASP.NET 3.5 website running for a long time along with a Reporting Services 2005 implementation.  So, that is, on our IIS box (Win 2003 Server, IIS 6), we have our custom .net website and the Reporting Services web services and Report Manager config'd, all on the same box.  The SQL Server 2005 databases (for RS and our own app) are on a separate physical box.</p>
  
  <p>We are now attempting to upgrade to .NET 4.  So I installed the .NET 4 framework on our web server.  We used VS2010 to upgrade our custom ASP.NET 3.5 site to 4 and pushed over the updated web.config to the web server.  Our custom web site is working great under .NET 4, but we are no longer able to run reports (either via our custom integration in our website or even by going to the Reports Manager configured URL).</p>
  
  <p>In either case we get the following error:</p>
  
  <p>"Could not find permission set named 'ASP.Net'"</p>
  
  <p>I've been doing some searches on the error, but so far haven't found anything that's hitting home.  Any thoughts, help would be greatly appreciated.</p>
