Much like Google’s GWT, Microsoft’s new Volta project compiles .net assemblies into client side ajax interfaces without requiring a line of javascript.

From the press release:

You architect and build your application as a .NET client application, assigning the portions of the application that run on the server tier and client tier late in the development process. You can target either web browsers or the CLR as clients and Volta handles the complexities of tier-splitting. The compiler creates cross-browser JavaScript for the client tier, web services for the server tier, and all communication, serialization, synchronization, security, and other boilerplate code to tie the tiers together. In effect, Volta offers a best-effort experience in multiple environments without requiring tailoring of the application.
