InfoStrat.VE: Integrating Virtual Earth 3D into WPF and Surface Applications for Mere Mortals [InfoStrat.VE: Integrating Virtual Earth 3D into WPF and Surface Applications for Mere Mortals]

keydet — Wed, 17 Jun 2009 18:16:00 GMT

Virtual Earth 3D has many applications, but until recently has only been practical on the web with a JavaScript interface. WPF applications could not use the full potential of Virtual Earth 3D without requiring a WPF wizard and some XAML magic due to Win32 interop limitations.

Information Strategies (InfoStrat) has the solution. They created a WPF / Surface control, InfoStrat.VE, and are sharing with the community on CodePlex. This control provides a WPF interface for the Virtual Earth 3D control, complete with data binding for camera control and WPF-based pushpins. All Win32 restrictions (air space control, no rotation or visual brush) are eliminated. Microsoft Surface is also supported.

Watch the interview to learn the history behind the control, see it in action, learn how to get started, and even contribute back to the community.

The video is a little long, so we have provided a timeline below in case you want to skip to specific sections:

SnagL: Visualizing Government Data using Silverlight [SnagL: Visualizing Government Data using Silverlight]

keydet — Tue, 16 Jun 2009 08:45:00 GMT

SnagL, from Berico Tailored Systems, is a thin client collaborative link analysis tool, which can be integrated with any existing tool or data repository. Advanced analytics, like clustering and ranking, enables users to intuitively navigate massive amounts of data through a thin client in a web browser.

SnagL is used by U.S. Government customers to help visually analyze, determine relationships in, and make decisions based on data. Watch the interview with members of the team to learn about the product, see a demo of it in action, and how it uses Silverlight to deliver compelling data visualizations that go beyond what you might expect from a browser based application. The team also gives you a history of their early adoption of Silverlight, evolution of SnagL, and how Silverlight enabled them to “see things you wouldn’t normally see just looking at the data.” They also talk about how Silverlight gave them a level of performance and visualization in the browser unmatched by their previous approaches. Finally, the team shares their excitement to start incorporating capabilities coming in Silverlight 3.

US Public Sector Developer Dinner for Partners - Silverlight Business Applications [US Public Sector Developer Dinner for Partners - Silverlight Business Applications]

keydet — Mon, 26 Jan 2009 12:23:00 GMT

This is a recording of the US Public Sector Developer Dinner for Partners covering "Building Business-Focused Applications Using Silverlight 2 and Beyond" held on January 15, 2009 in Reston, Va.

Business-focused applications, sometimes referred to as Line Of Business (LOB) applications, are almost universally about working with data in some shape or form. At it’s a heart, a business app needs:

A way to move data between tiers
A way to shape data (sort, filter, etc.)
A way to bind & display data
A way to soundly apply business logic

What you will learn:

In this session, we’ll start off by discussing approaches to building this kind of functionality TODAY using Silverlight 2. Next, we will give you a peek into how a future version of Silverlight will make building these applications even easier. You will learn about an exciting new technology that is all about making business applications for RIA (Rich Internet Applications) much easier to build. You will hear how we've made n-tier application development as simple as traditional 2-tier, provided application level solutions to developers, and how we're doing all of this with the same .NET platform and tools on both the client and server.

Hosting a Workflow in a Local Executable using Workflow Services Part I [Hosting a Workflow in a Local Executable using Workflow Services Part I]

keydet — Thu, 17 Apr 2008 23:40:00 GMT

When the Windows Workflow Foundation (WF) was first introduced in the .NET Framework 3.0, the only way to host a workflow in a client application was to use the WorkflowRuntime class programmatically, start the runtime, and create/start an instance of a workflow. Furthermore, if you wanted to communicate between the client code and the workflow logic, you needed to ues a ExternalDataExchangeService. This required a fair amount coding effort to get even the simplest of workflows up and running. The .NET Framework 3.5 introduced Workflow Services which are Windows Communication Foundation (WCF) Services authored as workflows. Workflow Services give you a new way to accomplish this scenario using a much simpler, cleaner, and arguably more elegant approach. In this three part screencast, I show you how to improve on the more manual hosting + ExternalDataExchangeServices approach by hosting a workflow in a client executable using Workflow Service.

Part I - Reviewing the SimpleExpenseReport application from the Create a Sequential Workflow tutorial so we can compare the two approaches. The application explicitly hosts the WorkflowRuntime & uses ExternalDataExchangeService

Part II - Walking through the fundamentals of creating a Workflow Service and hosting the Workflow Service locally

Part III - Walking through my rewrite of the SimpleExpenseReport application using Workflow Services.

Source code for the Workflow Services version of SimpleExpenseReport is available at http://cid-1f72da7294089597.skydrive.live.com/self.aspx/Public/WCF_WF/SimpleExpenseReportWorkflowServices.zip.

Re: Exposing/Consuming RSS/ATOM using WCF 3.5 & Silverlight 2 [Exposing/Consuming RSS/ATOM using WCF 3.5 & Silverlight 2]

keydet — Fri, 11 Apr 2008 20:40:44 GMT

I don't think there is necessarily a right or wrong answer here. I think it is a bit of a stretch to suggest I have declared request improperly. It would be more accurate to say that I have declared request in a way that you dislike for valid reasons. You make some really good points about the side effects of using var. I appreciate you making these points because it is very important for people to understand the side effects you mention. Unfortunately, I can't cover every detail about all the technology in use in a screencast/demo. If I did, the screencast would have been at least twice as long:).

You may be right about laziness. I find myself using var in a number of scenarios I suspect you would dislike. Maybe I am using it so much because I’ve done quite a bit of JavaScript/AJAX programming of late and it has become a habit. Who knows? I think one could argue a number of technologies such as intellisense, code snippets, and many more have made me a lazier programmer over the years. I surely know that I can't code in notepad or vi like I used to because of my dependency on both IDE and language features. Then again, it is also fair to say that the productivity gains outweigh the dependency on the features.

With the var keyword, it seems the documentation at http://msdn2.microsoft.com/en-us/library/bb383973.aspx would somewhat support your statements since it says “It is recommended to use var only when it is necessary, that is, when the variable will be used to store an anonymous type or a collection of anonymous types.” However, like any documentation, it is a recommendation. I still believe the use of var is a matter of preference. Am I misusing the var keyword? That’s in the eye of the beholder. I know where you stand:).

Scott Guthrie has a great eight part series titled First Look at Silverlight 2 where he walks you through building a Silverlight 2 sample app from scratch. The walkthrough highlights almost all of the key features of Silverlight 2 Beta 1. The walkthrough is so comprehensive that I have been using a slightly modified version of it for my Silverlight 2 presentations. Since I am a big fan of seeing vs. reading, I asked Scott if it would be ok if I turned his written walkthrough into a video walkthrough delivered as a Channel 9 screencast. Scott gave me the thumbs up so I put together what turned out to be a three part screencast. Here are the direct links for each part:

In my previous Silverlight Closed Captioning screencast here, I showed you how to use Expression Encoder to import Closed Captioning information to produce a solution without writing a line of code. What if you store your Closed Captioning information in an external data source (database, SAMI file, XML file, etc.) and want to keep it there? Do you have to reprocess all of your videos using Expression Encoder? Of course not, but you do have to write some code:). In this screencast, I show you how to use Silverlight, ASP.NET AJAX, and the Windows Communication Foundation (WCF) to solve this problem.

You can download the sample code via my blog at http://devkeydet.spaces.live.com/blog/cns!1F72DA7294089597!452.entry.
