Sonu Arora and C. Venkatesh: WCF Line of Business Adapter SDK

Posted: Aug 15, 2007 at 12:01PM

By: Charles

I recently got a chance to sit down with some of the folks behind the WCF LOB Adapter SDK. Meet Sonu Arora, Program Manager, and C. Venkatesh, Principal Group Manager. Here, we talk about, well, the WCF LOB Adapter SDK. What is it, exactly? What's it for? Why did we make it? How did we make it? Can unmanaged developers take advantage of it? Tune in to find out the answers. For those of you who have no idea what WCF LOB Adapter SDK means:

WCF Line of Business Adapter Team says:

Developers face the challenge of building services that interoperate across organizational and platform boundaries, and connect to existing line-of- business (LOB) systems. At the same time, these services and LOB systems evolve independently of each other, making connecting applications and services a constant challenge.

To simplify this problem for partners and customers, Microsoft has created a common framework based on Windows Communication Foundation (WCF) – the WCF Line-of-Business Adapter Software Development Kit ( WCF LOB Adapter SDK). With the WCF LOB Adapter SDK, developers now have a consistent and repeatable way to build LOB Adapters for the .NET platform.

For developers and partners, this means a common adapter that can be used across the entire .NET platform, not just a single endpoint like SharePoint or BizTalk Server.

The WCF LOB Adapter SDK ships with a rich set of development tools to automate and simplify adapter development in a consistent and repeatable manner:

For Adapter Developers

•	Adapter Development Code Generation Wizard
•	Visual Studio 2005 Integration (IntelliSense, context-sensitive help)
•	Runtime Components (LOB System Connection Pooling, Metadata Cache Lookup)

For Adapter Consumers

•	Add Adapter Service Reference Visual Studio Plug-In
•	Consumer Adapter Service BizTalk Project Add-In

I am a frequent visitor to Channel 9 over last year.

I have been noticing recently that the size of the videos posted have increased to the point where I cannot stream the video and watch it without the video stopping to catch up.

I have a 1.5mbps connection which is the maximum bandwidth that my ISP supports without a change to different technology. My ISP is the biggest in my country and this probably what 80% of users have.

I do not see the reason why the videos posted should have increased as previously every was fine.

Are you trying to alienate your existng user of channel 9 and people with similar bandwidth to mine. I am not going to upgrade my bandwidth which I already pay to much for just to watch your videos.

The quality of previous videos has been fine also and this should ot be a reason for increased size.

I have read many other posts with the issue as me here.

This must mean that channel 9 doesn't care if it loses any users of channel 9 due to this issue and if thats the case then fine you have lost me.

As I mention I have above average bandwidth in my country and this should be enough to watch streaming video without pauses.

Thank you for your feedback, Malcom. Of course we care! In the next version of C9 you will see multiple sizes for videos. We've had to increase the bit rate of our videos to satisfy new requirements of our publishing system.

I like the higher bandwith

But I thought that the streamed videos where multi-bitrate encoded for just the reason the poster above mentioned?

Yes man really we need different sizes of videos ...
Why not charles - divx rip videos , by using some free software so that quality is not lost but size becomes small ...
Really i would like to see that happen....

& waiting for some gr8 ..... Anders Hejlsberg video ...... Whats going on for future in C# .....

The difficulty in consistently providing video that can be streamed over standard DSL connections really sends a bad message about Microsoft's competence.

Uhm. These are, and have always been, multiple bit rate streaming files... The files that have grown significantly are the download files as they are now encoded at 2.5 Mbps. I'm not certain I understand the issue entirely now that I think about it. Again, streaming files are encoded to support various connection speeds...

Also, is there no feed back on the contents of this video? I found the SDK in this case to be rather interesting and useful. Thoughts?
