Silverlight: Client-Side Database via LINQ and Isolated Storage

Sat, 11 Oct 2008 07:32:51 GMT

When I did a search on "Silverlight Database" there weren't many results, and none of them actually mentioned a small database that you could embed into your Silverlight application. So, I thought I'd share a solution that I've used to store application data on the client using a combination of LINQ and Isolated Storage. This actually gives you a small "SQL"-like database since you can use LINQ to interact with it.

IsolatedStorage as a Silverlight object cache

Tue, 30 Sep 2008 06:50:34 GMT

Someone posed this question ("Can you use IsolatedStorage in Silverlight as a more reliable browser caching technique?") to me and I answered with my usual optimistic "in theory, yes" answer. Of course I had never tried it which is horrible to answer that to someone without trying it. In working on creating some Silverlight business application samples, I figured I should probably look at this scenario to see if a) it would work and b) it makes sense. I'll at least try to answer "a" here.

Tip of the Day #20 - How to Increase your Isolated Storage Quota

Tue, 23 Sep 2008 06:01:44 GMT

Each application by default is given 1 MB of storage space through Isolated Storage where the server is able to store client specific data on the clients machine. So what if you need more than 1 MB? Fortunately, the IsolatedStorageFile object provides a method called IncreaseQuotaTo() that allows a server to prompt the user for permission to increase the amount of storage.

Silverlight Tip of the Day #19: Using Isolated Storage - Silverlight T

Tue, 23 Sep 2008 06:00:57 GMT

Silverlight uses Isolated Storage as a virtual file system to store data in a hidden folder on your machine. It breaks up the data into two separate sections: Section #1 contains administrative information such as disk quota and section #2 contains the actual data. Each Silverlight application is allocated its own portion of the storage with the current quota set to be 1 MB per application.

Isolated Storage in Silverlight 2 Beta 2

Thu, 03 Jul 2008 01:08:53 GMT

Silverlight 2 allows you to store data safely and locally in a hidden folder outside the browser's cache, via a feature called 'Isolated Storage'. In this article, we will see how to create and read files in the isolated storage space. We will also see how to increase the default space limit for isolated storage

Frictionless data persistence in Silverlight 2

Thu, 26 Jun 2008 21:18:47 GMT

This article will show you how to work with plain objects in Silverlight code, and use attributes to have those values automatically persisted in IsolatedStorage, or a compressed version of IsolatedStorage. You can also use this approach to define your own targets, all without writing any plumbing code around your state objects.

Compression in Silverlight 2 : porting SharpZipLib

Thu, 26 Jun 2008 21:08:16 GMT

Maximize the user's IsolatedStorage capacity in Silverlight applications. This article provides a way to use stream compression in Silverlight to shrink your storage payload, by porting ICSharpCode's SharpZipLib project into Silverlight 2 Beta 2.

Increase Disk Quota for Isolatated storage in Silverlight

Tue, 25 Mar 2008 08:29:59 GMT

Isolated storage is a facility that lets you read/write (transient) data without worrying about other applications accessing this data. We first introduced this in Silverlight about a year ago with the alpha release. Its support was fairly basic though, and you couldn't store more than 1mb of data per application. We have given this feature an upgrade in Silverlight 2 beta 1. Although the default limit is less than it was before (100kb instead of 1mb), you can now ask the user for a larger quota. You can do this by calling IsolatedStorageFile.TryIncreaseQuotaTo(long):

Silverlight Isolated Storage for persisting form data

Fri, 01 Jun 2007 11:31:01 GMT

Silverlight has a special version of Isolated Storage which opens up some interesting scenarios when it comes to persistence. One interesting scenario would be to allow a user to save a draft of a form so they could come back later and fill out the rest of the form.

Does IsolatedStorage work as expected under Windows Vista?

Get flying with Isolated Storage in C#

Tue, 12 Sep 2006 04:01:01 GMT

Isolated Storage is a place on the disk where your .NET application always has write permissions. That makes it ideal for applications that need to store information such as settings or XML without first asking for permission. Application types such as ClickOnce or non-installable applications would benefit hugely from this capability.
