You've heard plenty about the Sterling database engine on this blog. I recently released version 1.5 which extended the reach of the database and added several feature requests. My article on Sterling for Isolated Storage on Windows Phone 7 was also recently published in MSDN Magazine. The phone has made this a very popular engine and it has been ...

I was at the MIX 2011 event. There was an ''Open Source Fest'' before the event and I came to showcase the Sterling NoSQL Database project that I run (and code most of, although there have been numerous enhancements and patches now added by a growing team of fantastic supporters). I was happy to speak to several people who hadn't heard of the ...

I'm exploring the phone more and more and came across the case of allowing the user to enter digits. One thing to keep in mind on the phone is that the form factor requires approaches to input that are different from the traditional desktop. A desktop application might handle numeric entry by simply filtering the text box, but that assumes a ...

I recently released a new open source project called simply UltraLight.mvvm. The purpose of this project is to make it easier to build MVVM-based applications that support tombstoning (a must) on Windows Phone 7. The DLL is 22KB and the source is less than 300 lines of code. With that, the framework supports: Commands Command binding for ...

Yesterday I wrote about an ultra light Windows Phone 7 MVVM Framework and mentioned that I would deal with tombstoning in a later post. This is the post. Sterling makes tombstoning very easy because it handles serialization of just about any type of object. To show an example, we'll start with the concept of a view model that holds a set of ...

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 a huge advocate of the Managed ...

Sterling changeset 72063 [browse the source code here] introduces triggers. The trigger is a powerful feature that allows you to universally intercept database operations. Their application in Sterling resolves several concerns, including: Validation — prevent a save operation from succeeding if data integrity is compromised, or prevent a ...

Sterling is an object-oriented database that I created to facilitate ease of serialization of data in both Silverlight 4 (soon 5) and Windows Phone 7 projects. Sterling was designed with a few goals in mind. It is not a true relational database and not intended to replace one. I'm confident certain offerings such as SQLite or even a trimmed down ...
