Los Angeles (CA) - In the later stages of today's keynote presentations at Microsoft's Professional Developers' conference, four of the company's more celebrated developers, including C# creator Anders Hejlsberg and COM pioneer Don Box, publicly unveiled a staggering array of new programming platforms including the company's Atlas programming model.
What got everybody's attention, though, was when Anderson had the idea to add a query to the sample Web services application that queried the geographical location of the computer that ran the original running processes query, using only available data as criteria. The results were funneled through a socket that brings up the geographic location in a Microsoft Virtual Earth map. So with a minimum of effort, two programmers - albeit two very capable ones - were able to exploit a publicly-accessible Web service in a seemingly unrelated Web application, pretty much on a whim, or at least what was prepared to look like a whim.
But to drive the point home, the team deployed the application on a PowerBook running OS X Tiger, where the same front end appeared in a Safari window.
To recap the array of new programming technologies unveiled today that made this demo possible: To the .NET programming platform, Microsoft is introducing Language Integrated Query (LINQ), a built-in relational database that integrates datasets into programming languages such as C# and Visual Basic, without the use of APIs (external function calls). LINQ is a language extension, not an external library. It relies on a relational database engine based on the company's Yukon technology, which verifies that some part of SQL Server will become a permanent part of Windows.
The query generated by LINQ produced a list of results in XML format. An Extensible Application Markup Language (XAML) front-end (the new term for "user interface") was crafted to produce a complex graphical form. But when a whimsical change was made to the underlying data, the form could be readily edited to encompass output in a format that was dynamically defined for the task at hand. In other words, no API or library had to be crafted for exploiting geographical location data from Virtual Earth; the information was simply leveraged and utilized on the fly.
