An AJAX toolkit like GWT is announced for .NET developers, called ‘Volta‘. (link)
In a nutshell:
The idea is that you start out building your application, focusing on
the functionality, the look and feel, until you’re satisfied with it
and then you repurpose it into an AJAX application or whatever,” Erik
Meijer, Volta’s principal architect and a member of Microsoft’s SQL
Server team, said in an interview. “You incrementally morph a standard
client-only application into a Web application. The programmer
specifies the intent and then we’re going to insert all the necessary
code to do the ‘how.’
