Interview FAQs

No. System.Net.Mail can only send email. To read email you either need a Mime parsing component such as aspNetMime or a POP3 component such as aspNetPOP3.
Absolutely. You can use them the way you always have. But note that the controls have been enhanced to be able to interact with data source controls and to use automatic data binding. For example, you can bind a DataList or Repeater control to a SqlDataSource control instead of writing ADO.Net code to access the database.
The DataGrid control has been superseded by the GridView control, which can do everything the DataGrid control does and more. The GridView control features automatic data binding; auto-generation of buttons for selecting, editing, and deleting; automatic sorting; and automatic paging. There is full backward compatibility for the DataGrid control, and pages that use the DataGrid will continue to work as they did in version 1.0 of ASP.Net.
Both models function the same and have the same performance. The choice of using single-file pages versus code-behind pages is one of personal preference and convenience.
Yes. Individual controls render markup that is compatible with the XHTML 1.1 standard. It is up to you, however, to include the appropriate document type declaration and other XHTML document elements. ASP.NET does not insert elements for you to ensure XHTML compatibility.
No. Each page can be written in a different programming language if you want, even in the same application. If you are creating source code files and putting them in the \Code folder to be compiled at run time, all the code in must be in the same language. However, you can create subfolder in the \Code folder and use the subfolders to store components written in different programming languages.
ASP.Net configuration data is encoded in XML and stored as plaintext files. You can access these files programmatically by using administration tools or by using a text editor
System-wide configuration settings and some ASP.NET schema settings are stored in a file named Machine.config, which is located in the %SystemRoot%\Microsoft .NET\Framework\versionNumber\CONFIG directory. This directory also contains other default settings for ASP.NET Web applications in a file that is referred to as the root Web.config file. ASP.NET configuration files for individual Web sites and applications, which are also named Web.config files, can be stored in any Web site root directory, application root directory, application subdirectory, or all of these.
ASP.Net configures IIS to deny access to any user that requests access to the Machine.config or Web.config files.
Yes. By setting the location element Override attribute to false, you can lock a specific setting so that it does not inherit settings from below.
