Jounce MVVM WCF RIA Printing and More Example

I finally managed to update and upload my To-Do List Reference Application. This is a Silverlight 5 application based on my Jounce framework that demonstrates a number of different features. I built it as part of my book, Designing Silverlight Business Applications. There are several chapters devoted specifically to the construction of this example application.…

Video: Getting Started with Jounce MVVM and MEF for Silverlight 5

I created a quick video to help you get started with using Jounce. The video starts with a blank slate, steps through installation of Jounce and the creation of a sample view model for a simple contact record that includes validation. You can access the video directly at http://vimeo.com/jeremylikness/jounce-getting-started, or view it below: Jounce: Getting…

Most significantly, of course, the code base has been updated specifically to target Silverlight 5. A number of bug fixes, feature requests, and Silverlight 5 features have…

Using Jounce Navigation to Create OOB Child Windows in Silverlight 5

One of the reasons I prefer to manage navigation as an event, rather than a strongly typed interface or handler, is because it allows for so much flexibility and extensibility in the navigation pipeline. In my Jounce framework, for example, the basic navigation event simply wires up an instance of a view to a view…

Using Visual States to Set Focus on a Control

A common problem encountered in Silverlight applications is how to set the focus properly when transitioning between controls. For example, in the reference application I’m writing for the book Designing Silverlight Business Applications there is the option to either edit an existing record or create a new one. The result of clicking the appropriate button…

Jounce Part 15: Asynchronous Sequential Workflows

One common complexity developers face when writing Silverlight applications is the fact that most operations are forced to asynchronous. When using the Asynchronous Programming Model (APM) or an event-driven model, these operations force the developer to consider the “chain of events” and provide the right code to correctly manage the sequences. Microsoft will address the…

Announcing Jounce 1.0 RTM – It’s here!

Jounce is the result of building composite Silverlight enterprise applications for a variety of verticals since Silverlight 3.0 and finding the common problems that needed to be solved. I found many frameworks to be too heavy for the task and always wondered why more did not tap into the native advantages that the Managed Extensibility…

Jounce Part 13: Navigation Parameters

This was a busy morning for Jounce. I checked in some changesets that unfortunately break backwards compatibility but address a few highly requested changes. The first was CLS compliance, and that involved refactoring some weirdly named methods. The second was consistent namespaces (had view vs. views, etc.) so that was cleaned up. The final and…

Jounce Part 12: Providing History-Based Back Navigation

I purposefully kept the navigation engine in Jounce light because there are so many opinions about how navigation should work and what makes sense for a specific application. A foundation is provided to raise navigation events and wire view models to views, but the rest of navigation is a mix of region management and user…

Jounce Part 11: Debugging MEF

The Jounce framework specifically relies on the Managed Extensibility Framework to help solve MVVM concerns. I recently presented an introduction to MEF and explained what I believe are the four core problems it solves: Discovery — it’s good to decouple, but at some point you need to provide an implementation, and MEF does a great…

An Ultra Light Windows Phone 7 MVVM Framework

I’ve been doing more work on Windows Phone 7 applications. Because of the smaller footprint of the phone and the way the application is hosted, I don’t believe the phone requires the same types of tools and frameworks as the browser. Sharing code and services is something that is obviously important, but while I am…

The Visual State Manager Explained

This evening I presented a talk that dove into the details of Silverlight’s Visual State Manager. I enjoyed the talk and had a terrific crowd with some very good questions. The deck explains much of what I went into with the talk, including exactly how the VSM works from when and how it starts and…
