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 Or _ HostProtectionResource.SelfAffectingProcessMgmt)> _ Private Shared Sub [Exit](ByVal Message As String, ByVal Code As Integer) ' Exit the sample when an exception is thrown. Console.WriteLine((ControlChars.Lf & "FAILED: " & Message & " " & _ Code.ToString())) Environment.ExitCode = Code Environment.Exit(Code) End Sub 'Exit
