Tonight I ran into the following error message when using a freshly installed version of SQL Server 2008 in a new project. Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created.

Hi everybody, My name is Jan Blessenohl and I am working on the new Telerik object relational mapper named OpenAccess ORM.

Tracking down those pesky flaws in a piece of code is, in my humble opinion, the most challenging part of software development. Thankfully we have a top-notch debugger built into Visual Studio.

Well, I was lucky enough to attend John Cunningham's talk at PDC last week and learned quite a few valuable tips that enhanced...

Overall, we got quite good impression from the UIA Verify tool, I wrote about last week. Yet, there is an issue that provoked me to download the source and modify the tool behavior. As a tester, I believe the automated tests should pass only when you get the full test running through all the actions and verifications.

I’ve modified the source so now the failed preconditions cause test ...

The new release of RadControls for Microsoft Silverlight is out with a couple of new controls and tons of improvements in the old components. In case you’ve missed, the new demos are uploaded and available here.
