If you think Smartphones are cool, you should meet some of the guys and gals behind it! Meet Neil Enns and Ori Amiga, Lead Program Managers, in this MSDN TV online broadcast. They demonstrate how to build an online weather application in less than five minutes using Visual Studio .NET 2003, Visual C# and a next generation Smartphone device. Next generation Smartphones will have .NET Compact Framework in ROM which means that developers can use Visual C# or Visual Basic .NET to develop Smartphone applications.
<rave>Even if you are not a developer, you should check this out! Neil and Ori rock. I've had the privilege of meeting them in person and they simply rock.</rave>
The demo shows how you can, with just two lines of code, create an online Web Services enabled Smartphone application! The application is shown to run both in an emulator and on a real device. Very cool!

Very cool. It's nice to see that it's as easy on the Smartphone OS as it is for PPC and the PC.
Too bad the SDK isn't available for a while longer.  I wish they wouldn't tease us like this.

I don't want a demo. I want a beta!

It was a nice little demo, but it's no where close to any type of real functioning application. The web services piece is the easiest part of any coding now-days. I could have done the same thing in Java years ago, two controls on a form is the farthest thing from reality you can get.
If you noticed, they didn't establish a GPRS or any other type of data connection, or monitor it. That requires access to an API that is barely accessable from the .NET CF (Connection Manager). The .NET CF is still in its infantcy and has a long way to go before it is useable in a wide array of application scenarios.
Kenny.

Geez, Andy. Ori spent the whole day walking around work with a swelled head!  Seriously though, thanks for the kind words.

Hey Kenny,
You're right, it's definitely not a real application. It's tough to try and show a demonstration of building a complete, end-to-end, application in the 15 minutes we had. Still, we hope what we were able to show gets people excited about using the tools. We've done other presentations in the past at TechEd and MDC that show some more in-depth development. One excellent example is of a real-estate application that is written in .NET CF, uses SQLCE for data storage, and SQL Server Notifications for new house listings. It's very nifty, and the tools and techniques are the same as the ones we demo'ed in the MSDN clip.
Regarding GPRS, the nice thing about web services on PPC and SP is that you don't actually have to use connection manager. You just access the web service object and .NET CF will bring up the connection for you as necessary. We didn't show this in the demo since we wanted to illustrate debugging, but if we hadn't been connected to ActiveSync the SP device would have connected via T-Mobile's GPRS with the exact same code. You can give this a whirl today on a PPC device.

Neil,
I haven't programmed in years - but I've got some ideas for a few smartphone apps bouncing around in my head. A couple of questions for you:
1. Is it safe to say that an application developed for SP2003 using .NET will not be backwards compatible with SP2002?
2. I'm a little fuzzy on this web services thing. I searched the net, and couldn't find an answer to my simple question - are there a lot of publicly available web services? For example, is that temperature service available to anyone to use? If there are a lot, where can I go to get a listing?
Sorry if these questions are a little basic - but I'm trying to understand these things. Thanks for the demo.

That is correct. .NET apps will only work on Smartphone 2003 and later.

There are a lot of them available that you can use - plus its really easy to create your own. The most popular ones are provided by Google, Amazon, and the MapPoint team at Microsoft. A large catalog of others can be found at http://www.salcentral.com

We grabbed the weather service from www.xmethods.net which lists a bunch of web services. I've never actually seen salcentral, I'll have to check it out!
The specific web service we used was GlobalWeather, available at http://www.capescience.com/webservi...globalweather/.
As Robert replied, .NET apps built for the next generation Smartphone won't work on Smartphone 2002. You need the .NET CF runtimes and whatnot, and we are not going to release them for SP2002.
