The Volta technology preview is a developer toolset that enables you to build multi-tier web applications by applying familiar techniques and patterns. First, design and build your application as a .NET client application, then assign the portions of the application to run on the server and the client tiers late in the development process. The compiler creates cross-browser JavaScript for the client tier, web services for the server tier, and communication, serialization, synchronization, security, and other boilerplate code to tie the tiers together.

Many people, including me, are thinking that Volta is a clone for GWT. So I took advantage of the presence of Erik Meijer in Paris to make a small interview of him.
Erik Meijer is the co-creator of Link and the creator of Volta. He is an architect in the SQL Server group at Microsoft.
It was a real pleasure for me to meet this guy.
