In this chapter, you were introduced to ASP.NET 4 Framework. First, we built a simple ASP.NET page. You learned about the three main elements of an ASP.NET page: directives, code declaration blocks, and page render blocks.
Next, we discussed .NET Framework. You learned about the 13,000 classes contained in the Framework Class Library and about the features of the Common Language Runtime.
You also were provided with an overview of ASP.NET controls. You learned about the different groups of controls included in .NET Framework. You also learned how to handle control events and take advantage of View State.
We also discussed ASP.NET pages. You learned how ASP.NET pages are dynamically compiled when they are first requested. We also examined how you can divide a single-file ASP.NET page into a code-behind page. You learned how to debug and trace the execution of an ASP.NET page.
At the end of the chapter we covered installation issues in getting ASP.NET Framework up and running. You learned how to map different Virtual Directories to different versions of ASP.NET Framework. You also learned how to target different versions of .NET Framework in your web configuration file.
