This blog is quiet… too quiet. It’s been a busy couple of months since starting at Clarity in January. PowerPoint, for better or worse, became my after-hours IDE. Below you will find some of the recent talks accompanied by their slides and code. Hopefully I didn’t forget anything, but please shoot me a comment if I did! WindyCityGo Apr 5 – 6, 2012 WindyCityGo is a two-day conference in Chicago that covers all things mobile. This year they added Windows Phone to their lineup and I was invited to speak on “Real World Windows Phone Development.” My talk covered an intro to metro and supports my tutorial series on building a polished Stocks app for windows phone. And now that my speaking gigs are winding down I can finally get back to that series! GET THE CODE ...

Series Introduction and Outline This series is going to walk through building a polished, functioning Windows Phone app from start to finish. The app is called Realworld Stocks and the full source code will be available on CodePlex as the series progresses. I’ll be using Mercurial to encourage forking and maybe even pull requests from developers who want to contribute their own real-world solutions. View the Series Introduction and Outline Navigation Basics Even though this series assumes a basic understanding of Windows Phone development I want to briefly touch on the basics of page navigation. Windows Phone apps follow a basic stateless navigation paradigm very similar to that of a web app. Each page in the app is represented by a URL ending with .xaml. How to Navigate to a new Page (the bad way) ...

View the Series Introduction and Outline Choices In the Microsoft world we have no shortage of client and server-side HTTP stacks to choose from. Rather than try to cover every possible combination, and to prevent this topic from getting too long-winded, I will keep this part succinct. Our first major decisions revolve around the following options: SOAP or REST? WCF or ASP.NET MVC? Without getting too deep into it,...

View the Series Introduction and Outline The windows phone panorama Many apps lend themselves nicely to a Windows Phone Panorama. CTA Watch looks similar but it’s actually a Pivot with a background image. After going back and forth for a bit with Real-world Stocks I decided that the panorama looked pretty nice and went with it. Thanks again @Templarian for the background! Be sure to hit...

View the Series Introduction and Outline Caliburn.Micro Many Windows Phone Applications use a lightweight MVVM framework for basic infrastructure services. Realworld Stocks is going to use Caliburn.Micro. I have had great success with Caliburn.Micro in my previous Windows Phone and Silverlight apps. CM was created by Rob Eisenberg and is under active development and has a great community and following. This article is going to walk through a lot of Caliburn.Micro setup, but...

Hopefully as the series progresses we’ll end up with a pretty nice looking stocks app ready for marketplace submission.   Series Outline The following is a rough outline for how I expect this series to progress. Some parts will probably be...

Why? Because I should be able to Get Latest and F5! I think simplicity is a crucial measure of success in all software. I think being able to pull down the source code onto any developer machine and F5 is an important goal to strive for. Removing manual processes and streamlining the development workflow can yield huge productivity gains – especially when onboarding new developers. I believe databases should be provisioned and seeded automatically, all 3rd party libraries should be readily available in the repo, and any manual steps that must be memorized or documented should be avoided at all costs. But this hasn’t been easy on a Windows Phone device The aforementioned goals have been easily achievable in all of my projects except Windows Phone apps. A key component to this workflow is the magical variable known as localhost. When I F5 one...

This morning I received a Microsoft MVP award for Windows Phone Development. I’m really honored to be part of a community that really values knowledge sharing and continuous professional growth such as this. Over the past few years I’ve come to greatly respect and appreciate the vast amount of personal time that many people in the development community (both MVPs and non-MVPs) contribute to help drive our profession forward. I’d also like to offer a very special thanks to the entire Windows Phone Dev community for helping to expand this great platform into the consumer reach that it deserves. There is still a ways to go, but after the impressive world-wide launch of Mango across dozens of countries, carriers, and OEMs on a single day I think we can all agree that Microsoft is taking this seriously. I’m personally really excited to be in on the ground floor this...

A few weeks ago I was invited onto the Developer Smackdown podcast to muse about my adventures in Windows Phone development. That episode went live today, and can be found on iTunes/Zune under the series name “The Smackdown.” Of course it can also be streamed by any modern browser from the Developer Smackdown site. In this show, Mark and Clark sit down with Matt Hidinger and talk about building his app CTA Watch for Windows Phone 7. Matt discusses his experiences over this past year and shares a great deal of passion about the platform. i’m convinced, where can i get it? ...

I’ve just finished my new app called Transit Directions. As the name hopefully implies, the app helps people get around a city with public transit. It will provide step-by-step directions for 11 cities, with an interactive map to aid the experience. I spent a bunch of time polishing this app to replicate the native Bing Maps app experience, hopefully it paid off. I assume this functionality will be built into the native app with the Mango phone update, so this baby has a limited shelf-life. B

update I’ve updated the code to check for the MapZoom event; also fixed a typo of MapClick to MouseClick.   Original Post The Windows Phone Bing Maps control is very close to its desktop Silverlight counterpart, with few missing features. In fact none of the limitations have really impacted my phone projects, until today I ran into a peculiarly missing event: MouseClick. Without MapClick there is no built-in way (to my knowledge) to detect when the user taps on the map. The Map control unfortunately swallows all ManipulationCompleted events, and MouseLeftButtonUp/Down get fired even when the user pans or zooms the map, which we don’t want to concern ourselves with. Blend Triggers to the rescue The solution I came up with is a Trigger called MapTapTrigger. In meeting with a number of other WP7 developers over the past year I came...

I apologize this is a week late. Below is a zip which includes the slides and solution from my presentation on Caliburn.Micro. It should serve as a pretty good reference application for how to implement the most common functionality in Caliburn.Micro. I’ve also included a simple HTTP framework which can take advantage of Caliburn’s Coroutines to easily issue GET requests and parse the JSON response into a typed model.

At PDC'10 last year Microsoft showed their upcoming solution for sharing assemblies between different platforms (Windows Phone, Silverlight, and .NET) – dubbed Portable Library Projects. The release date is said to be H1 2011 so hopefully they are still on track, maybe even to be included in VS 2010 SP1. Until then, we are on our own… Derick Bailey actually prompted this post from his tweet a little bit ago, so I figured I would share the solution I used for Bus Watch Chicago.   step 1: define your entities/model in the client (WP7) project The domain for Bus Watch is public transit, so naturally some of my entities are Routes, Stops, Vehicles, Locations, etc. I define all of these classes in the WP7 project; the Route class can be seen below. The keen eye may have noticed that I defined Route as...

Portable Library Projects At MIX 10 Microsoft announced a rather modest code-sharing technique to allow Silverlight and .NET apps to share a small subset of System.* libraries. Well today at PDC Shawn Burke had a 60-minute session called “3-screen coding – Sharing code between Windows Phone, Silverlight, and .NET.” He unveiled a new Class Library project type called a “Portable Library” which can be directly referenced by any type of project. The obvious goal here is to share your core business logic between your various client-side applications. Thankfully Visual Studio will even trim IntelliSense within a Portable Library project to only APIs which have been specifically defined as portable between all application types. Release date for Portable Library projects is H1 2011 PDC Video: 3-Screen Coding   Async Programming Improvements Probably the most popular announcement today was “The Future of C# and VB” talk,...

So it’s finally version 1 complete. This app has consumed a chunk of my free time over the past couple months while I got familiarized with the WP7 tools, but it’s been a great learning experience. This was pretty much my first time doing any real Silverlight or XAML-based development. Using Blend was an absolute treat so I hope to use this tool much more in my future. Lots of features will be added in the next few months, including some city expansion. I look forward to really exercising my abstractions to see if I can really plug in new Transit Services as easily as I think I’ll be able to. ...
