ASP.NET Web Forms lets you build dynamic websites using a familiar drag-and-drop, event-driven model. A design surface and hundreds of controls and components let you rapidly build sophisticated, powerful UI-driven sites with data access.

 ASP.NET offers four primary development frameworks:

 

ASP.NET Web Forms

The Web Forms framework targets developers who prefer declarative and control-based programming, such as Microsoft Windows Forms (WinForms) and WPF/XAML/Silverlight. It offers a WYSIWYG designer-driven development model, so it's popular with developers looking for a rapid application development (RAD) environment for web development. If you are new to web programming and are familiar with the traditional Microsoft RAD client development tools (for example, for Visual Basic and Visual C#), you can quickly build a web application without having experience in HTML and JavaScript.

 

ASP.NET MVC

ASP.NET MVC targets developers who are interested in patterns and principles like test-driven development, separation of concerns, inversion of control (IoC), and dependency injection (DI). This framework encourages separating the business logic layer of a web application from its presentation layer.

 

ASP.NET Web Pages

ASP.NET Web Pages targets developers who want a simple web development story, along the lines of PHP. In the Web Pages model, you create HTML pages and then add server-based code to the page in order to dynamically control how that markup is rendered. Web Pages is specifically designed to be a lightweight framework, and it's the easiest entry point into ASP.NET for people who know HTML but might not have broad programming experience — for example, students or hobbyists. It's also a good way for web developers who know PHP or similar frameworks to start using ASP.NET.

 

ASP.NET Single Page Application

ASP.NET Single Page Application (SPA) helps you build applications that include significant client-side interactions using HTML 5, CSS 3 and JavaScript. The ASP.NET and Web Tools 2012.2 Update ships a new template for building single page applications using knockout.js and ASP.NET Web API. In addition to the new SPA template, new community-created SPA templates are also available for download.

Web.config is the file that controls the configuration of your ASP.NET website. Using the features of the ASP.NET configuration system, you can configure an entire server, an ASP.NET application, or individual pages. A Web.config file can be used to restrict access to pages in a folder.

The Global.asax file, also known as the ASP.NET application file, is an optional file that contains code for responding to application-level and session-level events raised by ASP.NET or by HTTP modules. The Global.asax file resides in the root directory of an ASP.NET application. At run time, Global.asax is parsed and compiled into a dynamically generated .NET Framework class derived from the HttpApplication base class. ASP.NET is configured so that any direct URL request for the Global.asax file is automatically rejected; external users cannot download or view the code in it.

SQL Server Express LocalDB is a lightweight version of SQL Server that has many programmability features of a SQL Server database. SQL Server Express LocalDB runs in user mode and has a fast, zero-configuration installation that has a short list of installation prerequisites. In Microsoft SQL Server, any database or Transact-SQL code can be moved from SQL Server Express LocalDB to SQL Server and SQL Azure without any upgrade steps. So, SQL Server Express LocalDB can be used as a developer environment for applications targeting all editions of SQL Server. SQL Server Express LocalDB enables features such as stored procedures, user-defined functions and aggregates, .NET Framework integration, spatial types and others that are not available in SQL Server Compact.

8.       A

For browsers that do not support HTML5, you can use Modernizr. Modernizr is an open-source JavaScript library that can detect whether a browser supports HTML5 features, and enable them if it does not. In the ASP.NET Web Forms Application template, Modernizr is installed as a NuGet package.

The Visual Studio 2013 project templates use Bootstrap, a layout and theming framework created by Twitter. Bootstrap uses CSS3 to provide responsive design, which means layouts can dynamically adapt to different browser window sizes. You can also use Bootstrap's theming feature to easily effect a change in the application's look and feel. By default, the ASP.NET Web Application template in Visual Studio 2013 includes Bootstrap as a NuGet package.

The ASP.NET Web Forms Application template includes a set of NuGet packages. These packages provide componentized functionality in the form of open source libraries and tools. There is a wide variety of packages to help you create and test your applications. Visual Studio makes it easy to add, remove, and update NuGet packages. Developers can create and add packages to NuGet as well.

When you install a package, NuGet copies files to your solution and automatically makes whatever changes are needed, such as adding references and changing you’re the configuration associated with your Web application. If you decide to remove the library, NuGet removes files and reverses whatever changes it made in your project so that no clutter is left. NuGet is available from the Tools menu in Visual Studio.

Built-in validator controls have been configured to use unobtrusive JavaScript for client-side validation logic. This significantly reduces the amount of JavaScript rendered inline in the page markup and reduces the overall page size. Unobtrusive validation is added globally to the ASP.NET Web Forms Application template based on the setting in the <appSettings> element of the Web.config file at the root of the application.

Entity Framework Code First is a NuGet library that enables code-centric development when you work with data. Put simply, it creates the database portion of your application for you based on the code that you write. Using the Entity Framework, you retrieve and manipulate data as strongly typed objects. This lets you focus on the business logic in your application rather than the details of how data is accessed.

Language-Integrated Query (LINQ) is a set of features introduced in Visual Studio 2008 that extends powerful query capabilities to the language syntax of C# and Visual Basic. LINQ introduces standard, easily-learned patterns for querying and updating data, and the technology can be extended to support potentially any kind of data store. Visual Studio includes LINQ provider assemblies that enable the use of LINQ with .NET Framework collections, SQL Server databases, ADO.NET Datasets, and XML documents.

Model binding extends data binding in ASP.NET Web Forms controls to work with code-focused data access. It incorporates concepts from the ObjectDataSource control and from model binding in ASP.NET MVC. To configure a data control to use model binding to select data, you set the control's SelectMethod property to the name of a method in the page's code. The data control calls the method at the appropriate time in the page life cycle and automatically binds the returned data. There's no need to explicitly call the DataBind method.

URL routing allows you to configure an application to accept request URLs that do not map to physical files. A request URL is simply the URL a user enters into their browser to find a page on your web site. You use routing to define URLs that are semantically meaningful to users and that can help with search-engine optimization (SEO).

20.   C

In an ASP.NET Web Forms application, exceptions can be handled based on a specific handling hierarchy. An exception can be handled first at the application level, then at the page level, and last at the code level.

When an application handles exceptions, additional information about the exception that is inherited from the Exception class can often be retrieved and displayed to the user. In addition to application, page, and code level, you can also handle exceptions at the HTTP module level and by using an IIS custom handler.
