Caching in ASP.NET with a dependency on the SQL Server

As I suspected when you use caching on ASP.NET 2.0 with SQL Server Dependency in SQL Server 2005 the system is not implemented with a polling mechanis as in previous versions of SQL Server. It uses the NOtifications Services to advise the ASP.NET that some cache item must be cleared. See Caching in ASP.NET with the SqlCacheDependency Class

Microsoft certification 70-536

I just watched an excellent presentation about the Microsoft certification 70-536 (Microsoft .NET Framework). I was very impressed by the quality of the presentation and the functionalities of the player itself! I have one certification made 3 years ago, and I want to do some more pretty soon, from what I could understand the first one to take for developers is the 70-536. The presentation gives a general explanation about the content of the exam. It also gives out some links to resources (pasted below).

• Books and training
• C# Online learning guide
• Practices Tests: measureup.com , selftestsoftware.com
• Blog about MS certifications

I want to get 2 kinds of materials (books?) one on the theory and one with exercises, but I still couldn't understand what's the best place for that (everyone I talk to uses some pirate memorize-the-answers books, but I think I don't want to go that way)
