Visual Studio under .NET

Visual Studio under .NET

Microsoft .NET, the software giant's language-independent architecture for enterprise applications, is a decisive departure from current Windows programming methods. Even the most intrepid developers have taken to the command-line tools supplied with the .NET software development kit (SDK), doing well enough with those tools to ask Microsoft to permit production use of .NET software. But to tackle large commercial projects, most developers need the help of a graphical integrated development environment (IDE) such as Visual Studio.NET.

The IDE is a developer's control panel providing access to project management, source code control, editing, debugging and documentation. With the release of Visual Studio.NET slated for sometime in 2001, Microsoft is attempting to deliver an IDE that will meet such a comprehensive set of criteria.

Visual Studio.NET's unified interface should improve productivity and reduce error rates. Developers will no longer have to jump among applications. Keeping the coder's focus in one place and easing the management of projects that incorporate elements from different language should result in getting cleaner, more creative code to market sooner.

Microsoft's current professional IDE, Visual Studio 6, doesn't live up to its billing as a unified development environment. Visual Studio 6 is actually several IDEs with similar features. To work on a project that uses some C++, some Visual Basic, and some server-side JScript, the developer must open four applications: Visual C++, Visual Basic, Visual InterDev and the MSDN Library viewer. A professional Visual Studio developer's Windows taskbar is crowded with development tools, inviting errors because it falls on the developer to keep the interlanguage links straight.

Formerly known as Visual Studio 7, Visual Studio.NET is the next major release for Microsoft's development environment. This time the integration is complete: all of Microsoft's major programming languages - C++, C#, JScript, Visual Basic, Transact-SQL and Visual FoxPro - share a single GUI. The documentation viewer is now part of the IDE, not a separate application as it is in Visual Studio 6.

Visual Studio.NET is the least stable part of the .NET preview, so Microsoft chose not to make it publicly available with the .NET SDK. An updated beta release is forthcoming. For our first look, we set .NET aside and looked at Visual Studio.NET's overall worth as a development environment. Is there value to it beyond its .NET features?

Visual Studio.NET's fortunes are unquestionably tied to its facility with the .NET architecture, but even those who are reluctant to embrace .NET will find plenty to like in Microsoft's new IDE.

The layout utilises limited screen space more effectively, whereas in our tests, Visual Studio 6 was too confined on a 1024 x 768 laptop display, Visual Studio.NET feels less cramped. The main client area performs multiple duties as a text editor, Web browser and online help viewer. When multiple files are open for editing, their names appear on a tabbed list. Navigating through several open files in Visual Studio.NET is much easier. The tabs are more intuitive than Visual Studio 6's multiple document interface.

In its layout and behaviour, Visual Studio.NET feels like a cross between Visual C++ and Visual InterDev, which could take some getting used to for some Visual Basic developers.

Borrowing from the Web paradigm, Visual Studio.NET supports complete forward and backward navigation. If you tap the equivalent of the Back button, the editor returns you to the precise location of your previous work. This is a welcome change, as developers have wasted a lot of time in code editors just finding their way around.

This is also the first Microsoft editor to support multiple clipboards. It has taken a long time, but yes, developers can finally copy several blocks of code to the clipboard and selectively paste them into other modules. The navigation and clipboard features present pop-up lists so developers can jump straight to a specific destination or paste a given block of code.

So much of editing is repetitive. Developers sometimes use Unix's visual editor (vi editor) for its powerful macro facility. Visual Studio.NET is no match for vi in this regard, but it does have the capability of recording keystroke sequences and playing them back on an assigned keystroke. The macros can be edited and developers can bind them to commands and keys.

Visual Studio.NET's new command window offers keyboard-savvy developers relief from the tedium of point-and-clickdom. Most Visual Studio.NET functions have associated keywords that can be invoked from the command window. The macro and command window features will help make cross-platform developers more productive.

Microsoft bundled InstallShield with Visual Studio 6. InstallShield is a powerful installation tool, but its loose integration with the development environment causes it to ask questions the IDE could answer on its own. Now Microsoft has its own installation subsystem, dubbed Windows Installer, which Visual Studio.NET uses to reduce basic deployment to a one-button exercise.

We also found IDE shortcuts for remote deployment. It's now easy to build components, deploy them to remote servers, and launch a distributed debugging session. This emulates the modern clustered environment far better than Visual Studio 6, which has a strong preference for single-machine development and testing.

The preview of Visual Studio.NET really is a preview, and Microsoft warns us this early release may look or feel nothing like the retail version due in 2001. It's too immature to use for production work, but many of the issues related to stability and missing features have already been resolved and will appear in beta releases.

Microsoft's release of the .NET SDK proves that worthwhile Windows development can be accomplished without a graphical interface. Indeed, if Visual Studio.NET was too much like Visual Studio 6, many developers might stick with command-line tools. Fortunately, Visual Studio.NET has a broader agenda than merely putting a simpler, more colourful face on .NET. We'll continue to share our findings with you as Visual Studio.NET evolves, but our work with the preview leaves us looking forward to the next generation of Windows enterprise application development.
