Consider a seasoned brownfield (legacy or seasoned project; not new development) project with little to no unit tests. How and where do you start unit testing? Should you stop all forward development and refactor the entire solution at once to be testable? Probably not. Most brown field projects were not developed with testing in mind …

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 …

Since the start of my WP7 app, I have leveraged IOC (specifically Ninject) to fill dependencies on my ViewModels following the MVVM Light samples. To briefly summarize, I have an app level resource called Locator which provides properties for each of my ViewModels. These properties get the instance from the IOC container. Locator: public …
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, …
I recently had the need to change the state of a MediaElement to coincide with other page functionality. You can easily change the state of a MediaElement from the code-behind but you can’t unit test this. At first I thought, it would be easy to just bind the CurrentState property to a ViewModel property but …
