SecurityException: Request for the permission of type 'System.Web.AspNetHostingPermission

At times, files copied from other machine when directly used are marked as unsafe and thus when we try to use them we get such error. We need to mark it safe and give permission to access it via our code.

Here are few blog entries discussing it in detail with resoultions:
MSDN Blog: System.Security.SecurityException: Request for the permission of type - 1... [^]
MSDN Blog: System.Security.SecurityException: Request for the permission of type - 2...[^]
