Security Exception with ASP.NET project in Visual Studio 11

Question

I get this, to me, completely random error:

System.Security.SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Stack Trace:

[SecurityException: Request for the permission of type'System.Web.AspNetHostingPermission, System, Version=2.0.0.0, Culture=neutral,     PublicKeyToken=b77a5c561934e089' failed.]
System.Reflection.Assembly._GetType(String name, Boolean throwOnError, Boolean ignoreCase) +0
System.Reflection.Assembly.GetType(String name, Boolean throwOnError, Boolean ignoreCase) +42
System.Web.UI.Util.GetTypeFromAssemblies(ICollection assemblies, String typeName, Boolean ignoreCase) +145
System.Web.UI.TemplateParser.GetType(String typeName, Boolean ignoreCase, Boolean throwOnError) +73
System.Web.UI.TemplateParser.ProcessInheritsAttribute(String baseTypeName, String codeFileBaseTypeName, String src, Assembly assembly) +111
System.Web.UI.TemplateParser.PostProcessMainDirectiveAttributes(IDictionary parseData) +279

Whenever I try to run my asp.net site that uses a service I created. The site is part of a project that also contains the service.

I don't use IIS or other stuff so don't tell me about that pool thing.

Edit: I always have it

New project with new service and web site;
Framework 1.0 tot 4.0;
Adding to in the web.config file;
It's got nothing to do with IIS;

I might need to add that It's on my NAS.

Solved, well, partly, It gave the error because it was on my NAS.

3.5, the servers of my college are that. Other projects work. — reaper_unique, Jan 02 '12 at 14:41
Do you mean an actual Windows Service? How are you installing the service? What code is trying to use this service? — rtpHarry, Jan 03 '12 at 22:07
Exactly which version of Visual Studio are you using? There is no "Visual Studio 2011". — John Saunders, Jan 03 '12 at 22:45

The solution to the problem is that it was located on my NAS and that caused security issues. Moving it to a folder in my PC solved the problem.

nope, that's not it. The problem is when I change my web.config file to framework 3.5. I use Loginview btw. – reaper_unique Jan 02 '12 at 17:08
desperately trying to help you man: InsertAfter: /configuration/system.web/*[last()] – dotnetPr0 Jan 02 '12 at 17:24
Nope not working. It's really strange and frustrating since it's the first time I get this. The strange thing is that I can't find System.Web.AspNetHostingPermission in my web.config file. Adding it doesn't do anything either. – reaper_unique Jan 02 '12 at 17:32
Making a new clean 3.5 web site and copying that web.config file doesn't help either. – reaper_unique Jan 02 '12 at 17:38
one more thing I can think of at the moment is that the trust level is set system wide in the machine.config or smth. and you are not allowed to override it – dotnetPr0 Jan 02 '12 at 17:53
It's not only with framework 3.5, in 4.0 when I try to use MessageFault fault = ex.CreateMessageFault(); XmlReader reader = fault.GetReaderAtDetailContents(); I get it as well – reaper_unique Jan 03 '12 at 21:23
