Creating high performance WCF services

Mon, 05 Jan 2009 13:27:07 GMT

"I had a WCF service where I wanted to be able to support over a hundred concurrent users, and while most of the service methods had small payloads which returned quickly, the startup sequence needed to pull down 200,000 records. The out of the box WCF service had no ability to support this scenario, but with some effort I was able to squeeze orders of magnitude performance increases out of the service and hit the performance goal."

RIA in Sharepoint: Silverlight with 3D Extended DeepZoom - so cool

Thu, 20 Nov 2008 05:04:50 GMT

NOTE: There is an interesting contest to find an image in this. Check the post. Long story short, this is an effort to bring RIA to the SharePoint world. But not just RIA style usability, I believe we pushed the envelope even further by incorporating not only DeepZoom (SeaDragon) for 'zoom in to the pixel' resolution, but the 3D extensions not present by default (you have the essentials but only the amazingly talented people behind the Hard Rock Memorabilia site (vertigo) have shown this style of combined zoom/3d that we have seen in any largely deployed sample)

Creating Streamlined, Simplified, yet Scalable WCF Connectivity

Tue, 18 Nov 2008 08:48:45 GMT

"One of the most awesome things about WCF is that the concepts scale extremely well. If you understand the ABCs of WCF, then you can do anything from creating a simple Hello World to a complex sales processing service. It's all based on having an address, a binding, and a contract. All the other concepts like behaviors, validators, and service factories are simply supplemental to the core of the system. When you understand the basics, you have the general essence of all of WCF."
