(Almost) final VB 9.0 language specification posted

I wanted to let people know that an (almost) final VB 9.0 language specification has been posted on the download center. The spec is missing some copy-edits from the documentation folks, but is otherwise complete. Since I’m not going to get a chance to incorporate the copy-edits until I am back from vacation in January, I wanted to get the spec out there for anyone interested in documentation of the XML features that weren’t present in the previous version of the spec. (I apologize for the lateness of this vis-a-vis the release of the product itself, it’s been a busy fall.)

This updated language specification corresponds to Visual Studio 2008 and covers the following major new features:

  • Friend assemblies (InternalsVisibleTo)
  • Relaxed delegates
  • Local type inferencing
  • Anonymous types
  • Extension methods
  • Nullable types
  • Ternary operator
  • Query expressions
  • Object initializers
  • Expression trees
  • Lambda expressions
  • Generic type inferencing
  • Partial methods
  • XML Members
  • XML Literals
  • XML Namespaces

Questions, comments or criticisms can be sent to Thanks!

Volta released…

Just a little shout out to the latest project by that crazy language pimp, Erik Meijer. (He’s the guy you have to thank for much of LINQ and especially for XML literals in VB.) In its own words, Volta 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.

Although my focus continues to be on client programming by directly emitting IL for the runtime, I think Volta has some extremely interesting ideas contained within it. I’ll be interested to see how this project fares, especially given the success of his previous ideas…
