What is DOTNET / .NET Framework?
Dot Net (.NET) Framework provides an environment to develop, deploy and run the web applications, web services and windows applications. The .NET Framework consists of three main parts:
* The Common Language Runtime
* A Hierarchical Set of Unified Class Libraries,
* A Componentized Version of Active Server Pages Called ASP.NET
The .NET Framework provides a new programming model and rich set of classes designed to simplify application development for Windows, the Web, and mobile devices. It provides full support for XML Web services, contains robust security features, and delivers new levels of programming power.
Ques 2. What is "Common Language Runtime" (CLR)?
CLR stands for Common Language Runtime, It is the runtime that converts a MSIL code into the host machine language code, which is then executed appropriately. CLR is responsible to take care of the code execution of the program. CLR has following responsibilities
* Garbage collection
* Code Access Security
* Code Verification
* Application memory isolation
* Verification of type safety
* Conversion of IL to native code.
* Managing memory for managed objects
* Enforcement of code access security
Ques 3. What is CTS (Common Type System)?
Microsoft Introduce Common Type System to communicate two different languages in one common platform. CTS, common type system is the one which brings all .net languages data types on a common platform. It defines types like System.Int16, System.Int32 etc. A language may map 'int' to System.Int16 while another may map its 'int' data type to System.Int32.
Because all data types from all languages are mapped to common .net datatypes we can integrate code written in different .net languages into one assembly.
Ques 4. What is CLS (Common Language Specifications)?
CLS is the collection of the rules and constraints that every language (that seeks to achieve .NET compatibility) must follow. It is a subset of CTS and it specifies how it shares and extends one another libraries.
Ques 5. What is MSIL (Microsoft Intermediate Language)?
Any .Net application is compiled in two steps -- first the high level language compiler compiles it into MSIL and then the CLR compiles IL code into native code.
MSIL is Microsoft Intermediate Language which is platform independent.
MSIL that language independent code integration is possible. All languages are compiled into IL and then IL code is linked and converted to native code.
Ques 6. What is Managed Code?
Managed Code runs inside the environment of CLR i.e. .NET (dot net) runtime. All IL are managed code.
Ques 7. What is an assembly?
Assembly is a unit of deployment like EXE or a DLL. An assembly consists of one or more files and represents a group of resources, type definitions, and implementations of those types.
"An assembly is the primary building block of a .NET Framework application. It is a collection of functionality that is built, versioned, and deployed as a single implementation unit (as one or more files). All managed types and resources are marked either as accessible only within their implementation unit, or as accessible by code outside that unit."
Assemblies can be static or dynamic. Static assemblies can include .NET Framework types (interfaces and classes), as well as resources for the assembly (bitmaps, JPEG files, resource files, and so on). Static assemblies are stored on disk in portable executable (PE) files. You can also use the .NET Framework to create dynamic assemblies, which are run directly from memory and are not saved to disk before execution. You can save dynamic assemblies to disk after they have executed.
Ques 8. What are types of Assembly?
Assembly has two types.
1. Private Assembly: It is normally used by a single application, and is stored in the application's directory, or a subdirectory.
2. Public Assembly: It is normally stored in the global assembly cache (GAC), shared assemblies are usually libraries of code which many applications will find useful, e.g. Crystal Report Classes
Ques 9. What is a Web Service?
A web service is a component which runs on a server and supports clients to be connected using open protocols like HTTP and SMTP.
· It uses SOAP for wrapping its objects to travel on the network.
· It exposes itself via UDDI. Users can search for a web service using UDDI.
· A web service is described using WSDL.
. What is the transport protocol you use to call a Web service SOAP ?
HTTP Protocol
95. Explain role based security ? Role Based Security lets you identify groups of users to allow or deny based on their role in the organization.In Windows NT and Windows XP, roles map to names used to identify user groups. Windows defines several built-in groups, including Administrators, Users, and Guests.To allow or deny access to certain groups of users, add the element to the authorization list in your Web application's Web.config file.e.g.
< authorization >
< allow roles="Domain Name\Administrators" / > < !-- Allow Administrators in domain. -- >
< deny users="*" / > < !-- Deny anyone else. -- >
< /authorization >
96. How do you register JavaScript for webcontrols ?
You can register javascript for controls using Attribtues.Add(scriptname,scripttext) method.
97. When do you set "" ?
Identity is a webconfig declaration under System.web, which helps to control the application Identity of the web applicaton. Which can be at any level(Machine,Site,application,subdirectory,or page), attribute impersonate with "true" as value specifies that client impersonation is used.
98. What are different templates available in Repeater,DataList and Datagrid ? Templates enable one to apply complicated formatting to each of the items displayed by a control.Repeater control supports five types of templates.HeaderTemplate controls how the header of the repeater control is formatted.ItemTemplate controls the formatting of each item displayed.AlternatingItemTemplate controls how alternate items are formatted and the SeparatorTemplate displays a separator between each item displyed.FooterTemplate is used for controlling how the footer of the repeater control is formatted.The DataList and Datagrid supports two templates in addition to the above five.SelectedItem Template controls how a selected item is formatted and EditItemTemplate controls how an item selected for editing is formatted.
99. What is ViewState ? and how it is managed ?
ASP.NET ViewState is a new kind of state service that developers can use to track UI state on a per-user basis. Internally it uses an an old Web programming trick-roundtripping state in a hidden form field and bakes it right into the page-processing framework.It needs less code to write and maintain state in your Web-based forms.
