You'll need to set the legacyCasModel attribute on the trust element in your web.config to "true" in order for ASP.NET to run with this setting. I will blog about this in more detail later.

(ASP.Net Web Application on .Net 4.0 beta2 and a DevExpress control that has no .Net 4.0 support and has CAS). I've tried with the NetFx40_LegacySecurityPolicy configuration switch but the error I get is the same: This method explicitly uses CAS policy, which has been obsoleted by the .NET Framework. In order to enable CAS policy for compatibility reasons, please use the NetFx40_LegacySecurityPolicy configuration switch. Please see http://go.microsoft.com/fwlink/?LinkID=155570 for more information. Hi there,
