Some of the standard ASP.NET server controls allow the user to specify a template containing custom markup that will be used inside the server control. It is possible to create “.ascx” user controls that make use of this type of template. The MSDN documentation explains how.
When discussing the new features in Visual Studio 2008, LINQ gets most of the press. However, LINQ only works if you are targeting the .NET 3.5 Framework. Another new feature of Visual Studio 2008 is the ability to choose which Framework version to target, and sometimes you just don’t have the luxury of upgrading all your users to the latest Framework.

Clearly blog posts have been very sparse here, so I’m going to try something new. Whenever I find a good article or web site that helps me solve a particular problem I’m having, I’ll try to dash off a quick post referencing it. This’ll help me locate the information if I need it again later, and maybe it will help someone else find what they’re looking for too.
