64-bit support

The high performance and scalability of 64-bit processors and servers make them increasingly popular for hosting large Web sites. If you are developing Web applications to run on 64-bit servers, ASP.NET 2.0 is your solution. With integrated support for both 32-bit and 64-bit (Intel/AMD) processors within the development environment, ASP.NET makes it easy to cross-develop applications for multiple platforms while using a common source base. When you copy your 32-bit ASP.NET application code onto a 64-bit ASP.NET 2.0 server—no source code changes or manual re-compile required—it Just In Time (JIT) compiles and executes as a native 64-bit application. This capability supports native and managed development.
