Visual Basic code-named Orcas" (Visual Basic 9.0) introduces several language extensions that build on "Visual Basic code-named Whidbey" (Visual Basic 8.0) to support data-intensive programming—creating, updating, and querying relational databases, XML documents, and object graphs—in a unified way. In addition, Visual Basic 9.0 introduces several new language features to enhance Visual Basic's unique facility for static typing where possible, and dynamic typing where necessary. These new features are:
- Implicitly typed local variables
- Query comprehensions
- Object initializers
- Anonymous types
- Full integration with the Linq framework
- Deep XML support
- Relaxed delegates
- Nullable types
- Dynamic interfaces
- Dynamic identifiers
