Support for Test First Development

The integrated development environment (IDE) for Visual C# and Visual Basic is now able to create code stubs for new members and types even before they have been defined. This allows programmers to begin their process by writing tests and only afterwards create the code needed to compile those tests. The work is aided by the suggestion mode of IntelliSense, which prevents automatic completion of hitherto undefined members or types.

Visual Studio 2010 and Microsoft .NET 4.0 will be officially released by Microsoft today. If you want to experience the launch, you can watch the launch with the live webcast of the Microsoft Visual Studio 2010 Launch Conference and Expo, held at the Bellagio Resort in Las Vegas.
