Not sure how many people are planning on attending the PDC (Professional Developers Conference) this year, but it is going to be a fantastic conference. We announced some huge announcements on the PDC web site.  http://www.microsoftpdc.com/ We have Read More......( read more ) Read More......( read more ) Read More...

Here is an interesting problem we ran into recently.  The customer had a large GridView that was being updated by AJAX inside on UpdatePanel and seeing bad performance. The reason is that the Client-Side Javascript has to walk the entire DOM of the Read More......( read more ) Read More......( read more ) Read More...

We recently had a customer that wanted to sort a dynamic column in a DataGrid and so I thought it may be something that others would like to be able to do. You get your data for your dynamic column and then do something like below to insert it into an Read More......( read more ) Read More...

Don't be fooled with the EDM designer in SP1 beta for VS.NET 2008. Apparently there was no need "yet" for in depth customizability of the store model schema. For my class table inheritance example I'm using table prefixes since I'm running many examples on the same database. The prefix I'm using for this example is cti_ as you might have guessed. Everything works as you would expect until you try to write a linq to entities query. Instead of writing: var query = (from f in ctx.Players              where f.Name == "Roger"              select f).First(); I have to write, in order to have a...

I must be overlooking something. The ID field in my SQL Server database is configured to autoincrement through setting the Identity seed and Identity increment properties. For some reason the generated code allows the end user of the conceptual EDM model to set the ID property since it’s public. I would expect the setter to be at least private. Read More...

I'll be heading to Miramar, FL on July 8th for the local .NET User Group meeting to speak to the group about the Entity Framework and LINQ. I "hope" the final bits are released by then, but not on July 8th, please (yikes!). I went through a major overhaul of my demonstrations last week when the latest beta bits were released and it was the day before my last presentation on LINQ and the Entity Framework. It went well, but it was a bit too much "last minute" for me. Especially when I am spending every free moment writing my Silverlight book and its examples. There is a lot to demonstrate .... showing why it exists, how it works, how to use it with a real world application. There are also the discussions of where it is...

For those of you who have already put your feet into the waters of .NET 3.5 SP1, you have probably seen some amazing things with ADO.NET Data Services coupled to the Entity Framework. But that coupling may lead to blindness. Allow me to explain. [continue to article: Images as a Service with ADO.NET Data Services ] Read More...

I just finished writing the first draft of a sample I am including in my upcoming book tentatively titled Data Access with Silverlight 2 by O'Reilly . Without giving too much away yet since the final details of the contract are not set in stone, the application example consumes a REST service, manipulates it through LINQ to XML, and binds it to various controls and some composite controls. The interaction with the REST (REpresentational State Transfer) services is pretty slick and quite easy when using Silverlight and LINQ to XML. Of course there are always issues to deal with, but overall it works very nicely. Why use REST? Well, REST services are becoming more abundant on the web. They do not expose a contract like WCF so when you deal...
