New ASP.NET Goodies

by agrace 15. July 2007 17:52

Top of the list is the ASP.NET Futures release which is now available for download. The new Media Control is particularly helpful because up to now many developers had to purchase third party controls to present video in websites. The Browser History and Back Button Support is also being addressed for those of you interested in Ajax. This is an early developer preview, so you may not want to install it on your main development machine.

Speaking of Ajax, be sure to check out the new ASP.NET Ajax Control Toolkit as well as a host of new instructional videos and articles.

The new ASP.Net RSS Toolkit Version 2 has been released and enables ASP.NET applications to consume and publish RSS feeds. [More]

Some new tutorials have been added to ASP.NET Data Tutorials series.

Last but not least, get an early look at Visual Studio 2008 (aka Orcas). The official release of the 2008 line of products (Visual Studio 2008, Windows Server 2008 and SQL Server 2008) will be in Las Vegas next February.

I've recently been assigned the task of setting up and documenting the SharePoint development environment. If you were dismayed by the vagaries of the installation process, you've seen nothing yet. Although SharePoint is built upon ASP.NET, this is an Office product. The Office team have always been the cash cow of Microsoft. Apparently, their priority was to make this product user friendly. And if your company is so large as to have thousands of sites, I can see no better choice than SharePoint. It really scales better than anything out there.

For smaller companies with in-house development teams, there is still a huge hole in this market and it will be filled by someone. Very few users will get to see how "friendly" it is if the IT people determine that it's too much of a pain to develop on. Not only that, but very few IT teams have the expertise required to do this properly anyway. Training in this area has been pretty non-existent up to recently. Some months back, I attended a MOSS boot camp which was one of the very first in the United States. It focused only on the installation and administration of SharePoint. If you are a developer like myself, then for the most part, you are pretty much on your own.


The Bottom Line:

  * You have to develop locally for debugging and testing
  * You need SharePoint/WSS on your local machine
  * SharePoint/WSS needs Windows Server 2003 SP1 to run
  * You need to use virtual machine(s) locally to host Windows Server 2003
  * You may need to bump up RAM (4 Gb) and possibly add a fast external drive
  * TFS support will not be available until the Orcas release


Everything You Need to Know:

  * Use Virtual PC Differencing Disks to your Advantage
  * MOSS 2007 Development - Virtual Server Set Up
  * Team-Based Development in MOSS
  * Development Tools and Techniques for Working with Code in WSS 3.0
  * How to Create a MOSS 2007 VPC Image - the Whole 9 Yards



I will be implementing the development environment myself and will report back on the outcome. I am going to set up initially with Virtual PC VHDs and difference files on a test machine and work from there. Eventually, I will deploy to a staging server which will be an exact duplicate of the live server. As for source control, I will have to wait until the Orcas release and start all over again. There is a TFS Beta 1 available for those who are interested. Note that you can still save your Web Parts in the current version of TFS. There are hacks to getting the current version of TFS to work with MOSS solutions but it's supposed to be so involved as to not warrant the time spent on it. Also, some people are saying that VMWare is faster that Virtual PC (Virtual Server if you have the license) but I am trying to get some benchmarks to support this. I can't wait to actually sit down and build something!

End of the Impedance Mismatch?

On a practical level, yes. And with a rack of new technologies in the offing from Microsoft, we are sure to have a far more enjoyable programming experience in the near future than we have had up to now.

For almost three decades, object-oriented programmers have had to deal with the impedance mismatch issue. In essence, the programs we use to access our databases are object-oriented while the databases themselves are relational. There is not a direct mapping between them. And while much of it is fairly obscured through the use of the ADO.NET API, it would be fair to say that the two models are as similar as chalk and cheese.

In middle to large-sized projects, we typically use entity objects as object-oriented views of our relational data. The biggest problem has always been establishing the mapping between the two. This often entailed the use of third party tools such as NHibernate. An alternative approach was object-relational databases which I never did like.

Enter the Magic Triumvirate of LINQ, Orcas and the Entity Framework! This set of technologies promises to eliminate the impedance mismatch between the various data models and programming languages. With LINQ, we now have rich queries built right into the language and can access the data source whether it's XML, relational or objects. Orcas, the latest version of Visual Studio is currently available for download as a CTP release. The best bet may be to install the virtual PC version. I'm planning on doing this myself this weekend as I really want to get the feel of the new LINQ syntax. The only sour note in all of this is that the final version of Entity Framework won't be available until after the Orcas release. In the meantime, you can download the new CTP version of the Entity Framework.

Here's a simple LINQ query taken from 101 LINQ Samples:

public void Linq()
  List products = GetProductList();
  var productNames = from p in products
    select p.ProductName;
  Console.WriteLine("Product Names:");
  foreach (var productName in productNames)
