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....

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 feature will be removed in...

If like me, you have a “can’t live with it, can’t live without it” relationship with Crystal Reports and have made a significant investment in reporting with their tools, you might be digging around the VS2010 RC looking for Crystal. CR has been embedded into Visual Basic and Visual Studio for many versions...

Remember... the data service is an item template, not a project template….and that it’s been renamed to WCF Data Services. After you create a project (I usually use an empty web app to host the service), you can find the template in the Web section. Or just use the handy search feature in...

Hooray! Turns out it was a bug ("unintended breaking change) and it's getting fixed for RTM! :) [ see Connect submission and Microsoft's response ] Great catch George!

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...

In the first version of Entity Framework, if you wanted to create a PK/FK association between entities where there was no such constraint defined in the database you have to manually edit the SSDL (and lose that edit if you update the model from db). Why would you want to do this? The typical use case...

I had an email this morning from someone who was having trouble with reports populated using Entity Framework. He was running a report repeatedly but changing the filter.
