The 2.0 release was a major maturation of Microsoft’s managed platform. It introduced core pillars of modern .NET development, such as (allowing type-safe, reusable code), anonymous methods , and significant enhancements to ASP.NET and ADO.NET. But its true revolutionary feature for the x64 platform was its just-in-time (JIT) compiler . The framework included separate JIT compilers for x86 (32-bit) and x64 (64-bit) architectures. When a developer wrote C# or VB.NET code, they targeted the Common Language Runtime (CLR). At execution time, the x64-specific JIT compiler would translate the same Intermediate Language (IL) into native 64-bit instructions. For the first time, a mainstream development platform offered a seamless path: write once, run natively on both 32-bit and 64-bit hardware without conditional compilation or platform-specific hacks.
