Personal Note from Wally: My favorite quote from the discussion: "We're not looking for an ad-based play." The reason why I love that quote is that I was involved with a startup for almost two years that thought that advertising was the way to get a company to profitability. For those numbers to work, they would have to generate 25,000,000 page views per month. No one at that time, including Google, was generating that number of page views for a map oriented site. As you can guess, they did not survive. I learned a lot about what it takes to build a company.

ASP.NET Podcast Show #140 - ASP.NET 4.0 Ajax Databinding

admin — Tue, 28 Apr 2009 21:00:00 GMT

Show Notes:

First in a series of videos on an app I am creating that runs on Windows Azure.
Would you like to be involved in the app? If so, contact me through Email at wbm [at] wallym dot com or Twitter @wbm.
This is a preview, things will change. link: http://aspnet.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=24645
ASP.NET 4.0 AJAX Setup.
Running Application.
Some javascript regex from Simon Whatley. http://www.simonwhatley.co.uk/
Pseudo Columns.

$index.
$dataItem.

Databinding and Caching. Its probably better to chain the requests instead of running them in parallel, which is what my code allows to happen.
Upcoming Events:

INETA Live Webcasts with Rachel Appel and Steven Andrews.
geekSpeak with Jennifer Marsman and Glen Gordon.
TechEd - I won't be there, but it will be great.
State of Indiana Tour in June with INETA.

Ft. Wayne.
South Bend.
Evansville.

CodeStock in June.

PS. I started getting sick about 5-10 minutes into the show, so if I sound somewhat confusing after that, I apologize.

----- Code Sample Notes -----

Four (4) assembly references are needed for a cache project:
CacheBaseLibrary.dll
CASBase.dll
ClientLibrary.dll
FabricCommon.dll
Import System.Data.Caching for code using Velocity
You must start with a CacheFactory. No parameters in the construct means to read from a configuration file.
From there, cache is accessed via a CacheName. You can use Cache.DefaultCache for the default (returns null) For CTP2, you cannot easily seek out if a region is created.
Cache.DefaultRegion is null as well.
There is quite a bit of log messages that are exposed by default in Velocity. Especially for a Cache Miss.
