Solution that demonstrates the problem.

Console.BufferHeight and Console.BufferWidth do not return the correct values after a terminal window resize. The values are only updated after certain other interactions with the Console class, such as attempting to set CursorTop or Writing to the console.

The attached solution demonstrates the problem. After resizing, pressing any key will output the previous values for BufferHeight and BufferWidth. An additional keypress will output the new values, because they were updated by the call to Console.WriteLine.
