This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.
In the C family of languages and ALGOL 68, the word cast typically refers to an explicit type conversion (as opposed to an implicit conversion), causing some ambiguity about whether this is a re-interpretation of a bit-pattern or a real data representation conversion. More important is the multitude of ways and rules that apply to what data ...
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.

The reinterpret cast technique from C/C++ also works in Pascal. This can be useful, when eg. reading dwords from a byte stream, and we want to treat them as float. Here is a working example, where we reinterpret-cast a dword to a float:
Apple has topped the Drucker Institute's annual ranking of the 250 best-managed companies in the US. Fellow tech giants Nvidia, Microsoft, and Intel all made the top 10.
For example, according to Best Friends Network staff, cats can exist with barely noticeable behavioral changes as their loss of sight comes on gradually. As they start losing vision, felines begin ...
Compared to non-generic code with manual casts, these casts will be the same, [74] but compared to compile-time verified code that would not need runtime casts and checks, these operations represent a performance overhead. C#/.NET generics guarantee type-safety and are verified at compile time, making extra checks/casts are unnecessary at runtime.
