Two new videos that I have created for Visual Studio 2010 have just been published to Pluralsight On-Demand. If you don’t have a Pluralsight subscription (yet), these videos are available as part of POD’s free guest pass along with lots of other great content. The new vids are “ Exploring the Classes...

Yesterday I accidentally discovered that you can edit a multiplicity end point in the EDM Designer: It’s a known bug and is fixed already (post-RC). The changes don’t get saved with the EDMX....

These are the first two. I’ve got more coming! If you don't have a Pluralsight subscription, grab a free guest pass and you'll have have access since these are part of the subset of guest pass content along with a ton of other great videos. These will also be on MSDN online shortly....

Perhaps the title of this blog post will suffice, but I just wanted to highlight this problem. If you were to look up the timestamp data type in the SQL Server 2008 documentation, this is waht you will find within the topic article: “The timestamp syntax is deprecated.

This is an edge case that I had not noticed, but was brought to my attention this morning in an email from Dave Russell who pointed...

Thanks to Danny Simmons ' comment below clarifying that the provides that support EF3.5 will still work for EF4 " just without new provider affecting features like model first." As far as I can tell, and confirmed by Fabio Pandolfo (@fabiopand on twitter) who is also on the hunt, DevArt's Oracle...

In the process of updating my book, I have to recheck every statement and every line of code. A lot has changed. It’s as though I were writing the whole thing from scratch. Here’s a small but notable change that I found. In .NET 3.5 you cannot Load an EntityReference for an Added entity even...
