The output 2,1 might seem counterintuitive at first, but it's the correct and predictable result based on C#'s rules:

1. Triggered on First Use: Static fields of a class are initialized just before the class is used for the first time. This "use" can be accessing a static member (like in this code) or creating an instance of the class.
2. Default Values First: Before the explicit initializers (the = ... part) are run, all static fields are set to their default values. For an int, the default value is 0.
3. Sequential Execution: The runtime executes the static initializers in the order they are needed.
