ASP.Net Interview Questions and Answers Part 2

11.What is Common Type System (CTS)?

  • Common Type System (CTS) describes a set of types that can be used in different .Net languages in common. That is, the Common Type System (CTS) ensure that objects written in different .Net languages can interact with each other. For Communicating between programs written in any .NET complaint language, the types have to be compatible on the basic level.

  • These types can be Value Types or Reference Types. The Value Types are passed by values and stored in the stack. The Reference Types are passed by references and stored in the heap. Common Type System (CTS) provides base set of Data Types which is responsible for cross language integration.

 

12. What is Metadata and Assemblies?

  • Metadata is the binary information describing the program, which is either stored in a portable executable file (PE) or in the memory.

  • Assembly is a logical unit consisting of the assembly manifest, type metadata, IL code and set of resources like image files etc.

 

13. What is ADO.Net?

  • ActiveX Data Objects (ADO), It is the technology used for working with data and databases. It provides accesses to data sources like SQL server, OLE DB, XML etc.

  • The ADO .Net allows connection to data sources for retrieving, manipulating and updating data.

 

14. What is Windows Workflow Foundation (WF)?

  • Windows Workflow Foundation (WF) is a Microsoft technology that provides an API, an in-process workflow engine, and a rehostable designer to implement long-running processes as workflows within .NET applications.

  • The current version of WF was released as part of the .NET Framework version 4 and is referred to as (WF4).

  • A workflow, as defined here, is a series of distinct programming steps or phases. Each step is modeled in WF as an Activity

 

15. What is Windows Presentation Foundation (WPF)?

  • It provides a separation between the user interface and the business logic.

  • It helps in developing visually stunning interfaces using documents, media, two and three dimensional graphics, animations and more.

 

16. What is Windows Communication Foundation (WCF)?

  • It is a runtime and a set of APIs (application programming interface) in the.NET Framework for building connected, service-oriented applications.

 

17. What is LINQ (Language Integrated Query)?

  • 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.

 

18. What is an ASP.NET Web Form?

  • ASP.NET Web forms are designed to use controls and features that are almost as powerful as the ones used with Windows forms, and so they are called as Web forms.

  • The Web form uses a server-side object model that allows you to create functional controls, which are executed on the server and are rendered as HTML on the client.

  • The attribute, runat="server", associated with a server control indicates that the Web form must be processed on the server.

 

19. Why do you use the App_Code folder in ASP.NET?

  • The App_Code folder is automatically present in the project.

  • It stores the files, such as classes, typed data set, text files, and reports. If this folder is not available in the application, you can add this folder.

  • One of the important features of the App_Code folder is that only one dll is created for the complete folder, irrespective of how many files it contains.

 

20. What is ASP .NET HTML Server Controls

  • The HTML server controls are Hypertext Markup Language (HTML) elements that include a runat=server attribute.

  • The HTML server controls have the same HTML output and the same properties as their corresponding HTML tags. In addition, HTML server controls provide automatic state management and server-side events.

  • HTML server controls offer the following advantages:

    1. The HTML server controls map one to one with their corresponding HTML tags.

    2. When the ASP.NET application is compiled, the HTML server controls with the runat=server attribute are compiled into the assembly.

    3. Most controls include an OnServerEvent for the most commonly used event for the control. For example, the <input type=button> control has an OnServerClick event.

    4. The HTML tags that are not implemented as specific HTML server controls can still be used on the server side; however, they are added to the assembly as HtmlGenericControl.

    5. When the ASP.NET page is reposted, the HTML server controls keep their values.

  • For example, To use an HTML server control, use the following syntax (which use for the HtmlInputText  control as an example):

<input type=”text” value=”hello world” runat= server />
