ExternalProcessMgmtMight create or destroy other processes.
ExternalThreadingCreates or manipulates threads other than its own, which might be harmful to the host.
MayLeakOnAbortMight cause a resource leak on termination, if not protected by a safe handle or some other means of ensuring the release of resources.
NoneExposes no host resources.
SecurityInfrastructureExposes the security infrastructure.
SelfAffectingProcessMgmtMight exit the current process, terminating the server.
SelfAffectingThreadingManipulates threads in a way that only affects user code.

This enumeration is used by the HostProtectionAttribute attribute.

The following code example shows the use of the HostProtectionResource enumeration with the HostProtectionAttribute attribute. This example is part of a larger example provided for the HostProtectionAttribute class.

// Use the enumeration flags to indicate that this method exposes  
// shared state and self-affecting process management. 
// Either of the following attribute statements can be used to set the 
// resource flags.
[HostProtectionAttribute(SharedState = true, 
    SelfAffectingProcessMgmt = true)]
[HostProtectionAttribute(Resources = HostProtectionResource.SharedState |
     HostProtectionResource.SelfAffectingProcessMgmt)]
private static void Exit(string Message, int Code)
{
    // Exit the sample when an exception is thrown.
    Console.WriteLine("\nFAILED: " + Message + " " + Code.ToString());
    Environment.ExitCode = Code;
    Environment.Exit(Code);
}
