Sterling Isolated Storage Database with LINQ for Silverlight and Windows Phone 7


Sterling is a lightweight object-oriented database implementation for Silverlight and Windows Phone 7 that works with your existing class structures. Sterling supports full LINQ to Object queries over keys and indexes for fast retrieval of information from large data sets.
The goal behind Sterling is to keep it:

  • Non-intrusive. You shouldn’t have to change your classes just to persist them.
  • Lightweight. As of this writing, the DLL for Sterling is under 70 Kb. No one needs to bloat their project for something as simple as persisting data.
  • Flexible. While the core is light, Sterling is designed to handle any serialization task and make it ultra-easy to query databases using LINQ-to-Objects.
  • Portable. Sterling is designed to run on both Silverlight 4.0 and the Windows Phone 7.



Sample App:

Better Silverlight 4.0 Installation and Upgrade Experience

Perception is everything and how your application installs, loads and upgrades can make a big difference to how users feel about it. Out of the box, Silverlight doesn’t make things particularly easy, but don’t worry, with a little work, you can cover the bases.

There are a number of checks you need to make when a user first browses to a website that contains your Silverlight application. The figure below illustrates this.

Windows Phone 7 Life Cycle


One of the key dilemmas facing Windows Phone 7 programmers is how we maintain an extremely responsive experience for the user, provide some sort of multi-tasking and preserve battery life, all at the same time? The solution offered by Windows Phone 7 is to tombstone applications when they are inactive.  This tutorial will explore tombstoning, multi-tasking and the entire application life cycle in detail.

The guiding model for the entire lifetime of an application, from launch to termination, is called the Windows Phone Execution Model.  It is designed to provide a responsive system, at all times. The strategy to accomplish this is to avoid having two or more applications continuing to run in the background, competing for resources, slowing the foreground application and draining the battery.

To accomplish this, Windows Phone 7allows only one application to be running in the foreground, and no 3rd party applications are allowed to run in the background; even when they appear to do so.    When an application is moved to the background, but not closed, it is tombstoned.  Tombstoning means that the application is inert, but, the operating system maintains state information for the application. If the user returns to the tombstoned application, the state information is passed to the application before it is restarted, allowing the programmer to restore the application to the state it was in when it was tombstoned.  This can give the very effective illusion that the application was there all along.

Exit out of a Windows Phone Application


Scenarios for needing Exit

The two most common scenarios people cite when asking for an Exit method are because (a) the user failed accept a EULA, login to an account, or something else that renders the application inoperable, or (b) the application is in an unstable state due to unexpected errors, etc. and needs to be shut down.

The solution: Throwing Exceptions to Exit your Silverlight App

Peter Torr has a great blog post here about all the various scenarios you may want to exit a WP7 application and each of their side affects.  I would encourage you to read his post to learn more about this topic
