Microsoft released a beta of .NET 3.5 SP1 and VS 2008 SP1 releases. While devoted in great part to bug fixes, they also include new features, some that have been eagerly awaited. Versions of ADO.NET Entity Framework and the ADO.NET Data Services framework (Astoria) are included. Read more »

Now that VS 2008 is out of the box, so to speak, it appears that a new era in Windows development is upon us. Language-Integrated Query is one of several game-changing technologies now supported in the Microsoft software kit. Although it is still early and there is a lot of learning to do, LINQ is poised as a whole new way of developing with data.

It is fair to say that the first rush of .NET technology was about catching up with Java, although there was much unique about .NET too. With LINQ, for now, it seems Microsoft has stolen a march on the Java opposition.

I spoke recently with Jason Beres, director of product management at Infragistics, which is one of the major third-parties in the Microsoft market. Beres said people will take LINQ very seriously. “I think it going to be the de facto way to do any real data binding or object access moving forward,” he said.

With the new Microsoft tool kit comes Windows Presentation Foundation (WPF). Is WPF game changing? That is hard to say. When it was first conceived, the ubiquitous Web interface seemed to be overstressed, and ready to be replaced by a new generation of WPF-based Smart Clients that would use something like WPF. But, before WPF made it too market, AJAX came on strong as a means to give new life to Web interfaces.

This means the plate of companies like Infragistics is pretty full. Infragistics has just rolled out NetAdvantage for WPF 2007, which is compatible with Visual Studio 2008. At the same time, according to Beres, the company has been re-tooling its frameworks around ASP.NET AJAX as well.

For Infragistics and others, Silverlight looms as another alternative interface. Watch for Infragistics and others to provide Silverlight components, especially now that Silverlight 2.0 (which, more than its predecessor, rightly bears the mantle of “WPF/Everywhere”) arrives in its first beta form.

LINQ, WPF and VS 2008 have been primary areas-of-interest for the SearchWindowsDevelopment.com site for some time. We invite you to check out our LINQ VS 2008 pages, and to stay tuned.

Visual Studio 2005 provides an Web site application template to create AJAX enabled ASP.NET Web sites.

However, when you use Visual Studio 2008, you will not find this template in the New Web site creation templates.  The reason for this is that  Visual Studio 2008, by default creates a .NET Framework 3.5 application.  See the .NET Framework type at the top right section of the window image below.

AJAX is now integrated into the framework.  In Visual Studio 2008 all web sites that are created using .NET Framework 3.5 are AJAX enabled.  You don’t have to create a separate AJAX enabled web pages.

Bill Gates has been popping up a lot lately - at the Office Developer Conference, at the SharePoint Conference, and so on. An interesting leg on his journey - this is, after all, a farewell tour - was his stop at Stanford University on Feb 19.

The Stanford visit is one of many he’s made in recent years to drum up added interest in computer science among students. 

Programming seems less and less to be a career of choice, and this worries Gates. So he goes to colleges and addresses the students frankly about why he loves software.

It is not all together unlike his speeches to certified geeks. There is plenty of ‘neat’ stuff, ‘really cool’ stuff, and the funny video. But I’d recommend the Stanford transcript as a good entry point to a view on the state of computing today and over time.

Gates glosses over a few facts - there were, for example, software businesses before Microsoft. But he is right in saying his company was the major one to take the low cost-high volume approach to business software.

He discussed a dream ‘’required some heroic assumptions. ‘’

We had to believe that the cost of the hardware would come down. We had to believe that the volume would go up. And only then would the economics of being able to spend tens of millions of dollars to write a software package, and yet being able to sell it for say $100 or less, actually make sense.

Much software today is free. Microsoft does not mind that, if it is free too students who will go on to do way cool things, including perhaps becoming a Windows developer some day. At the same time Gates spoke at Stanford, the company announced its DreamSparks free software program, which Ed Tittel recently wrote about in ‘’Microsoft sparks creativity with DreamSpark student developer program'’ on SearchWinDevelopment.com.

The way you use Master pages has changed in Visual Studio 2008.  Remember, how in Visual Studio 2005 when you add a new Web Form in ASP.NET applications - you get to choose a master page to apply to the Web form.  If you choose to use a Master page - then the page that is added, when you check the HTML code for that page - it is stripped of all the standard HTML tags - only the Page directive and the <asp:Content> tags are available.  This is a Content page.

In Visual Studio there are two types of Web Forms available - Web Form and the Web Content Form. 

The Web Form is a standard Web Form - without the Master page, with its HTML code like a standard HTML page.  Whereas, the Web Content Form is the one to which you can attach a Master page.

The Web Form page also has a MasterPageFile property.  But, if you create a Web Form and then set the MasterPageFile property to link to your Master page you will get a run time error.

Content controls have to be top-level controls in a content page or a nested master page that references a master page.

This is because content pages must not have another other HTML tags or controls. 

If you want to use Master Pages use Web Content Form, otherwise use the Web Form.

Another nice feature in Visual Studio 2008 - is that in that in the top right corner of the Design window of the Web content page is a link to the Master page that this page is linked to.  Also, the “Split” view is cool.. you can now see the source and the design view tiled in the design area.
