ASP.NET 2.0 and Visual Studio 2005 Fundamentals

ASP.NET 2.0 introduced the built-in ASP.NET Development Server (Cassini), allowing developers to host and test web applications without requiring IIS installation. This made development more accessible and simplified the development environment setup.

GridView is the new data-bound server control introduced in ASP.NET 2.0, replacing the older DataGrid control from ASP.NET 1.x. GridView provides enhanced features like built-in paging, sorting, and editing capabilities with less code required.

SQL Cache Invalidation is a feature that automatically removes cached data when the underlying database data changes. This solves the problem of stale cached data by providing real-time cache updates based on database triggers, eliminating the need for fixed time-based refresh intervals.

ASP.NET 2.0's membership and roles system stores user authentication and authorization data in SQL Server Express by default. This provides a free, embedded database option for user management without requiring a full SQL Server license.

ASP.NET 2.0 provides three main site navigation controls: TreeView (hierarchical display), SiteMapPath (breadcrumb trail showing current location), and Menu (dropdown/cascading menu structure). All three work together to provide comprehensive navigation solutions.

In ASP.NET, the \App_Code directory is specifically designed to store raw source code files (such as .cs or .vb classes) which are automatically compiled at runtime. \App_Theme is used for styling, while Solution Explorer and Server Explorer are IDE tool windows, not directories.

Visual Studio 2005 provides two primary viewing modes for web pages: Design view (visual editor) and Source view (code editor). These tabs allow developers to switch between visual layout and HTML source code perspectives of the same page.

Tab Navigator refers to the navigation elements that appear at the bottom of ASP.NET pages, providing users with a way to switch between different sections or views. Smart tags serve different purposes in Visual Studio, while Page Tabs and Task bar are not standard ASP.NET navigation terminology.

The underline in Visual Studio 2005 code indicates Error Notification and Assistance - it marks syntax errors, compile errors, or warnings and provides assistance through smart tags or error lists. Smart tags appear as a small arrow glyph, not an underline. Code change notifications appear in different UI elements.

The Navigation control section in the Toolbox includes TreeView and Menu controls, which are designed for site navigation and hierarchical data display. Validation controls check input, Login controls handle authentication, and Standard controls contain basic UI elements like buttons and textboxes.

Web Parts controls in the Toolbox handle personalization features - they allow users to customize page layout, content, and appearance by adding, moving, or removing configurable parts. HTML contains basic markup controls, Data handles data source connectivity, and General contains miscellaneous controls.

Server Explorer in Visual Studio enables you to work with database connectivity - you can create, modify, and delete database connections, view database objects, and drag tables onto your designer. Solution Explorer manages project files, Properties Window shows component settings, and Toolbox contains UI controls.

Smart tags appear as a small arrow in the right-hand corner of server controls in Design view and provide quick access to common tasks like configuring data sources, formatting templates, or setting properties. Snippets are reusable code blocks, Tasks is not a feature, and Tag Navigator is unrelated.

Code snippets in Visual Studio 2005 are small, reusable code fragments that perform specific tasks (like creating properties, try-catch blocks, or for loops) and can be inserted freely into your code. Smart tags are context menus, Tasks are not snippets, and Puppets is not a Visual Studio feature.

Visual Studio 2005 can save settings including customizations like window layouts, keyboard shortcuts, toolbars, and other modifications to the development environment through the Import/Export Settings feature. This allows users to backup, share, or transfer their personalized IDE configuration.

Visual Studio 2005 targets Internet Explorer 6.0 as its default validation browser for ASP.NET pages. The other options represent either outdated browsers (IE 3.2/Netscape 3.0) or document type standards (HTML 4.01, XHTML 1.0) rather than the browser compatibility target.

The FTP Site location option in Visual Studio enables direct deployment to remote web servers via FTP. This allows you to create and modify ASP.NET applications on a remote server as if working locally, with changes synchronized automatically through the FTP connection.

The code-behind model separates presentation (HTML/markup) from business logic by placing code in a separate class file. This separation makes the application more maintainable and allows developers to focus on business logic independently of the UI layer, following better software engineering practices.
