Har utvecklat en applikation i 1.1, allt har fungerat bra och för 2 dagar sen bytte webhotellet till 2.0. Nu när jag försöker köra min applikation så får jag detta felmedelande

Description:
The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details:
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

Teknikerna på webhotellet vet inte vad felet kan vara, vi har tillsammans sökt igenom och testat olika saker. Är det någon som vet vad som är fel? Denna lilla kodsnutt fungerar inte...

System.IO.Directory.CreateDirectory(Server.MapPath("/img/skit/"))

Är det inte så enkelt att de inte tilldelat skrivrättigheter för till den anonyme användaren som surfar i din appplikation. Det verkar ju smälla när du skapar du försöker skapa en katalog?

Jag nästan exakt samma problem...

Vad jag läst så finns det inget att göra man kan helt enkelt inte ändra i web.config 1.1 versionen eftersom detta är en ren 2.0 grej med högre säkerhet. Man får snäät och vänligt acceptera detta eller byta ISP till någon som kör 1.1 om användaren önskar så...eller rätta mig någon om jag har fel?
