I'm running Windows 7 - x64 Edition with IIS 7.5
I have a simple asp.net website that i've run on other versions of windows and IIS but now, on SOME pages it gives me the following error
Exception information: Exception type: HttpParseException Exception message: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Stack trace: at System.Web.UI.TemplateParser.ProcessException(Exception ex) at System.Web.UI.TemplateParser.ParseStringInternal(String text, Encoding fileEncoding) at System.Web.UI.TemplateParser.ParseString(String text, VirtualPath virtualPath, Encoding fileEncoding) ......
Now, when i run this application under cassini everything works fine. I also was able to figure out that where ever i have used the AjaxToolkit controls those pages are throwing this error.
Any advice ?
In IIS, Under the advanced settings. You must try to set
Load User Profile=True
