Visual Studio "Whidbey" is a 2.0 release. Some of the new features include: generics,
iterators, partial types, operator overloading, C++ templates, code refactoring and
expansions, XML documentation in VB, edit and continue, data tips and data visualiser,
a .NET implementation of STL (STL.NET), OpenMP.
One of the key goals is productivity enhancements: from site membership to
data access, Whidbey reduces the amount of code that needs to be written. The DataSource
Fields tool window allows you to easily create data-bound controls. The documentation
now includes more code samples and links to community sites and annotations.
New set of My. classes in VB to make simple code easier. For example:
With My.Computer.Printers.DefaultPrinter .OutputType = PC.OutputType.Preview .PrintLine ("Here is some text...") .PrintLine ("Below is some ink from a Tablet PC:") .PaintPicture (Me.InkPicture.BackgroundImage, 35, 300) .EndDoc() End With
SmartTags automate common forms tasks (for example, a button can be easily anchored).
A new Publish Wizard can be used to create a URL-based deployment location using ClickOnce.
For web development, you can now open and work with web sites using FTP directly
as an alternative to FrontPage Server Extensions. ASP.NET can now generate XHTML,
and there are validators to help verify that a page can be viewed by different browser
ASP.NET includes a Master Page designer for template-based visual inheritance; you
can use this to generate the generic furniture that should be displayed on each page.
Master pages are stored with a .master file extension, and then other .aspx pages
can be based on this master page. New controls include the ZoneBar control, which
provides a web part-style container that can be minimised, moved and deleted automatically.
Site membership is dramatically easier - there's a series of login controls (Login,
PasswordRecovery, LoginStatus etc.) which automate the process of creating a personalised
site. ASP.NET does more than just providing login / password services, however - once
a user has been logged in their progress through the site can be tracked based on
The new GridView control automatically handles paging, sorting, editing and deletion
of data; a wizard allows it to be automatically configured using a web service.
Page layouts containing ZoneBars can be personalised with just a single line of code:
This information is persisted across sessions.
PDC attendees will receive a Tablet PC SDK Update that will enable context
tagging for controls (so that a numeric-only text box can be set up to only recognise
There are plenty of new features emerging on mobile devices for developers to support.
Demonstrated were a number of new innovative devices that have recently released:
- A Pocket PC from Toshiba with 640x480 resolution
- A new Pocket PC Phone Edition 2003 device with a built in webcam
- A new SmartPhone with a built-in keyboard
- A HP iPAQ 4155 Pocket PC with built-in Bluetooth and WiFi in a very small form factor.
Here's a sample of how the .NET Compact Framework will enable developers to build
really complex SmartPhone applications using .NET (the demo was actually done on Everett:
VS.NET 2003, rather than Whidbey):
// Grab a picture Camera c = new Camera(); pictureBox1.Text = c.GetImageFile(); pictureBox1.Image = new Bitmap(pictureBox1.Text); // Find the current phone location from the mobile operator Sensor s = new Sensor(); Report report = s.CurrentLocation(typeof(AddressReport)); string zipCode = ((AddressReport)report.ReportData).PostalRegion.ToString(); // Get the weather at the current location WS.WeatherServices ws = new myClaim.WS.WeatherServices(); WS.WeatherForecast forecast = ws.GetWeather(zipCode);
Whitehorse is part of Microsoft's Dynamic Systems Initiative. It builds into
Whidbey to provides designers to help visualise a service-orientated architecture.
You can create service bindings to enable logical to physical architecture mappings.
From a Component View tool window, you can drag and drop services to the relevant
zones and tiers and validate that they match enterprise policies (for example, impersonation
must be enabled).
Prefast (a tool used internally within Microsoft to detect buffer overruns) will be
included within Whidbey.
