It’s well established from both theory and practice that Web sites and Web services achieve scale through asynchrony. If a dedicated thread is required per client connection to a server, scalability becomes limited by the number of threads the server system can support, which is typically far fewer than business requirements demand. Unfortunately, it’s also been difficult historically for developers to write asynchronous apps, due to the myriad of callbacks that have been necessary to program asynchrony successfully. Thus, businesses scale by investing in many more machines rather than by making better use of the ones they already have or the few they’re paying for use of in the cloud. All that changes with the next release of Visual Studio and .NET. New features in managed languages make writing asynchronous code as simple as writing synchronous code, thereby enabling both developer productivity and good return on investments. In this code-heavy session, learn how you can be the hero of your organization, building efficient and scalable server apps that best utilize your company’s resources.
