Beginning ASP.NET 4 in C# 2010 note

1.
To quick check whether IIS is installed, try http://localhost
2.
When IIS is installed, it creates a directory c:\inetput\wwwroot
3.
The "Classic" application pool is only used to keep backward compatibility.
4.
Configure the website through IIS is an easier way than to edit web.config file
5.
Use debugging only while testing the web application: debug="true"
6.
To enable tracing, add Trace="true" to <% Page ...
and add Trace.IsEnabled = true; in Page_Load method
and you can add
 Trace.Write("") to add your own message
7. Application-Level tracing
add the below in web.config <system.web>
<trace enabled="true" ...>
and access through trace.axd
