Passing Certification For Enterprise Windows Phone 7.5 Apps
Your Enterprise Windows Phone 7.5 application has different requirements and restrictions than the majority of apps in the store. While we now have Windows Phone 8 with different distribution methods, your client may still have 7.X devices that require using targeted distribution via the store. You need to consider how to allow the certification team to test your app without exposing sensitive data or affecting production systems. There are a few choices you have: Supply the testing team with test ......

Key Windows Phone Development Concepts
As I am doing more development in and out of the enterprise arena for Windows Phone I decide I would study for the 70-599 test. I generally take certification tests as a way to force me to dig deeper into a technology. Between the development and studying I decided it would be good to put a post together of key development features in Windows Phone 7 environment. Contrary to popular belief the launch of Windows Phone 8 will not obsolete Windows Phone 7 development. With the launch of 7.8 coming shortly ......

Local LINQtoSQL Database For Your Windows Phone 7 Application
There aren’t many applications that are of value without having some for of data store. In Windows Phone development we have a few options. You can store text directly to isolated storage. You can also use a number of third party libraries to create or mimic databases in isolated storage. With Mango we gained the ability to have a native .NET database approach which uses LINQ to SQL. In this article I will try to bring together the components needed to implement this last type of data store and fill ......

My Favorite Free Windows Phone Twitter App
Windows Phone 7 has been out for about two years now. In that time I have switched back and forth with different free Twitter apps. Mostly the has been because someone has mentioned one or another that they like. I figured I would give a quick run down of what I felt were the pros and cons of each. These are only the ones that I have used and your mileage may vary. So here we go. WP7 Built-In Twitter Functionality While it is great that Microsoft put this functionality in, it is extremely limited ......

Using BingMapsDirectionsTask In Windows Phone 7
Windows Phone has a number of great capabilities built into it for developers. The Bing APIs allows you to easily give your application mapping functionality. You may just want to give users directions to a fixed location. What happens though when you want to give a user directions from their current location to an address that they are picking from application data? This article will cover just that scenario. Since almost everything in Windows Phone development is asynchronous this can get a little ......

Reading QR Codes In Your Windows Phone App
I have recently been working on an application for a client that needs to read QR codes. This has lead to some interesting findings. There are a couple of approaches you can use. One is to take a picture and evaluate it for a code and the other is more like the Bing Vision feature. Both of them can be accomplished by leveraging theSilverlight ZXing library from Codeplex. In order to have QR code images to test I would suggest going to It is a site where you can freely generate QR images ......

Features I’d Like To See In Windows Phone 8
With Windows Phone 8 around the corner I figured I would get the wish list out. I am encouraged by what we have seen so far. This is a short list of the things that have bugged me over the last two years of using and developing for the platform. I realize that some of them are pure fantasy and will never happen, but we can dream. So here we go. Separate volume controls for phone and alerts Videos can be taken in portrait and will be saved that way Tweets created in the People Hub should be able to ......

Creating Corporate Windows Phone Applications
Most developers write Windows Phone applications for their own gratification and their own wallets. While most of the time I would put myself in the same camp, I am also a consultant. This means that I have corporate clients who want corporate solutions. I recently got a request for a system rebuild that includes a Windows Phone component. This brought up the questions of what are the important aspects to consider when building for this situation. Let’s break it down in to the points that are important ......

TechEd 2012: A Little Cloud And Too Little Windows Phone
It is Monday afternoon and the last couple of sessions have been disappointing. I started out in the Nokia: Learning to Tile session. I guess I should have read the summary more closely because it turned out to be more of a Nokia/WP7 history and sales pitch. “I’m outa here!” I made a quick venue change and now we are learning about Private Cloud Architecture. The topic and the material were very informative. The speaker even had a couple of quotable statements. The first quote was “You can trust ......
