Question

Answer 1

You can use ReSharper's annotations to fix this. ReSharper has no way of knowing how long the closure will last, e.g. it might be assigned to a field, and so it warns you that you might possibly be using something that will be disposed by the time the lambda is called.

You can fix it like this:

void DoThisTwice([InstantHandle] Action action)
{
    action();
    action();
}

The InstantHandle attribute tells ReSharper that the action is called immediately and not stored beyond the scope of the method.
