  • Blog Post: UPDATE: Porting Silverlight RIA to Windows Azure (Data Access)

    Given all latest changes to SDKs and tools, I think a significant update is needed for my old blog post on creating a data access layer for Azure Table Storage in Silverlight ( Porting Silverlight RIA to Windows Azure - Part 1 ). It is now a part of whitepaper I'm working on, soon to be released on MSDN...
  • Blog Post: What is RCA (Rich Cloud Application)?

    Rich Cloud Application (RCA) is a concept describing a new type of Rich Internet Application (RIA) served from the cloud. To the end user it would look exactly like RIA but with additional functions that take it to the next level - peer awareness, session awareness and duplex communication with a server...

  • Blog Post: Scalable Duplex Messaging with Silverlight 3 and Windows Azure

    Silverlight 3 comes with very good PollingDuplex library allowing two-way communication between a server and a client but it lacks scalability features allowing it to work from behind a session-less load balancer such as one in Windows Azure. This limits options for implementing large-scale applications...
  • Blog Post: [Really] scalable Silverlight-Azure duplex implementation

    Following up on my previous posts on this topic, this time I want to present really scalable solution to the problem of scaling client-server two-way communication in Silverlight 3 in the cloud.

  • Blog Post: Azure-friendly Polling Duplex in Silverlight 3

    One of the most serious limitations of current implementation of PollingDuplex mechanism (one that allows server to talk to Silverlight applications in the browser) in Silverlight 3 is its lack of support for multiple backends. In other words, if your environment includes multiple machines or does not...
  • Blog Post: Porting Silverlight RIA to Windows Azure - Part 3: Implementing Service Bus Azure Proxy for Silverlight (SBAPS)

    One major area where hosting RIA in Azure is significantly different from hosting in a regular web server is the use of the foundational piece of Azure platform itself - .NET Services Service Bus. Service Bus is an “intermediary in the cloud” allowing you to implement all kinds of patterns which were...
  • Blog Post: Porting Silverlight RIA to Windows Azure - Part 2: Efficient data access

    Firstly, why is implementing efficient data access important for Azure RIAs in particular? The cloud databases in general are not the most performant databases in the world – they scale well but any given response by itself is probably going to be slower (e.g. much slower) than in traditional stand-alone...
  • Blog Post: Porting Silverlight RIA to Windows Azure - Part 1

    UPDATE: Please refer to an updated version of this post for up-to-date steps working with Azure SDK November CTP and Silverlight 3 and Silverlight 4 Beta.

  • Blog Post: Product Support Online Architecture

    Following up on my previous post - the reference application is now called PSO (Product Support Online). It will be developed in two phases to align features better with the changing nature of Azure and SDS APIs, but more importantly, to draw a clear line between on-premise applications and cloud-based...

    Here’s new project I'm working on which is taking after my CPM pet project and various Azure and Silverlight projects I've done with partner ISVs.

    This week I attended a MIX09 session (well, the one that is supposed to be presented there in March anyway) by Rick Barraza, Senior Experience Architect at Cynergy . Rick is well known for his work on Flash, Flex, AIR, Silverlight and WPF projects and is a big proponent of Silverlight as the RIA platform...
  • Blog Post: SharePoint SilverView 1.0 released to the web!

    SharePoint SilverView 1.0 Guide Pack has finally been released to the web this week.

  • Blog Post: Mediator design pattern in Silverlight

    I've recently published a code sample showing how to implement a Mediator design pattern in Silverlight 2.

  • Blog Post: Resource sharing in Silverlight 2 : workaround

    Resource sharing in Silverlight 2 isn't as easy as in WPF - it only works for certain resources such as brushes, and that's not goint to change in Silverlight 3 either. For example, if you want to reuse geometry paths you will get an error: <UserControl x:Class="PaulTest.Page" xmlns=" http:...
