.NET 4.0 // C#

In .NET 4.0 SecurityManager.IsGranted is obsolete

An article by Ogi Ivanov 2 Comments

In .NET 4.0 SecurityManager.IsGranted has been made obsolete.  This is what it was and if you compile in .NET 4.0 compatibility it will complain.

bool isGranted = SecurityManager.IsGranted(new SecurityPermission(SecurityPermissionFlag.Infrastructure))

In order to fix this now you have to do this instead. 

var permissionSet = new PermissionSet(PermissionState.None);
permissionSet.AddPermission(new SecurityPermission(SecurityPermissionFlag.UnmanagedCode));
bool isGranted = permissionSet.IsSubsetOf(AppDomain.CurrentDomain.PermissionSet);
