 If you are not concerned about forwarding cancellation notifications to lower invocations, you can either:
 
 Explicitly pass `default`:
 
 ```csharp
-        public static void MyMethod(CancellationToken c)
-        {
-            MyMethodWithDefault(default);
-        }

 Or explicitly pass `CancellationToken.None`:
 
 ```csharp
-        public static void MyMethod(CancellationToken c)
-        {
-            MyMethodWithDefault(CancellationToken.None);
