6:
Why can't you simply double-click on an ASP.NET file to run it?

An ASP.NET page must be processed by a Web server. If you double-click on it, you're trying to open the file without using that process.
7:
What is a virtual directory?

A folder on your computer that can be accessed from a browser as though it were in your root directory (typically, c:\inetpub\wwwroot).

If you created a file called hello.aspx and placed it in the c:\inetpub\wwwroot\tyaspnet21days\MyApplication directory, how could you access it from the Web browser?
What's the difference between code declaration blocks and render blocks?
A1:
Code render blocks are inline code, denoted by <% and %> tags, and aren't compiled. Code declaration blocks define a page's methods and members, are denoted by script tags, and are compiled.
