I had an issue on a WP 7.0 app the other day that I spent several hours working on after Bing offered no help. Its rare to find an exception that no one has blogged or posted about. So I’m going to share my learning. The scenario: I have a REST JSON service that I’m …

Its been a while since I used IsolatedStorageSettings from scratch. I wrote a wrapper several months ago and its just worked since. So when I was working on a side project recently (very recently) I was pulling my hair out trying to figure out why IsolatedStorageSettings didn’t appear to be working. I could add an …

I spent several hours last night trying to find a good example of an extra wide, horizontally wrapping Panorama Item but couldn’t find one. Several of the built in hubs have this layout and I knew there were third parties who had done the same so it should be possible. I like how this layout …

MANGO UPDATE – This code bombs in 7.1. Remove the converter to make it work. I guess that static resource is no longer provided. I went back and tested to see if anything changed in 7.0 when you remove the converter and didn’t notice any difference. So I’m not really sure what it did to …

I haven’t been able to view one of my pages in the VS designer for several weeks. Just gave me a stacktrace. I tried to figure it out a couple times but could never find the source of the problem. VS just didn’t give me any help in narrowing down the cause. I opened up …
James Ashley posted a great tip on simplifying tombstoning by abstracting IsolatedStorageSettings.ApplicationSettings and PhoneApplicationService.Current.State to a common interface IDataStorage. This makes storing either temporary state data or more permanent settings data much easier with less code. This was a very good post but the duplication on the two IDataStorage implementations made me cringe a little. …
No new content in this post, but wanted to share my findings on charting with MVVM on the phone. I initially started with Visifire. They have some really nice charts and features out of the box but I kept hitting brick walls with databinding and MVVM. They do have some databinding but it isn’t enough, …
