NET is an integral part of many applications running on Windows and provides common functionality for those
applications to run. This download is for people who need .NET to run an application on their computer. For developers,
the .NET Framework provides a comprehensive and consistent programming model for building applications that have
visually stunning user experiences and seamless and secure communication.

When .NET was introduced it came with several languages.
VB.NET,
C#,
COBOL
and
Perl, etc.

Intermediate Language is also known as MSIL (Microsoft Intermediate Language) or CIL (Common Intermediate
Language). All .NET source code is compiled to IL. IL is then converted to machine code at the point where the software
is installed, or at run-time by a Just-In-Time (JIT) compiler.

Code access security (CAS) is part of the .NET security model that prevents unauthorized access of resources and
operations, and restricts the code to perform particular tasks.

Assembly is physical grouping of logical units, Namespace, logically groups classes.
Namespace can span multiple assembly.

A)Choosing a language compiler
B) Compiling the code to MSIL
C) Compiling MSIL to native code
D) Executing the code.

The .NET Framework is shipped with compilers of all .NET programming languages to develop programs. There are
separate compilers for the Visual Basic, C#, and Visual C++ programming languages in .NET Framework. Each .NET
compiler produces an intermediate code after compiling the source code. The intermediate code is common for all
languages and is understandable only to .NET environment. This intermediate code is known as MSIL.

Managed extensibility framework (MEF) is a new library that is introduced as a part of .NET 4.0 and Silverlight 4. It helps
in extending your application by providing greater reuse of applications and components. MEF provides a way for host
application to consume external extensions without any configuration requirement.

The System.GC.Collect() method.

There is no difference between int and int32. System.Int32 is a .NET Class and int is an alias name for System.Int32.

Tuple is a fixed-size collection that can have elements of either same or different data types. Similar to arrays, a user
must have to specify the size of a tuple at the time of declaration. Tuples are allowed to hold up from 1 to 8 elements
and if there are more than 8 elements, then the 8th element can be defined as another tuple. Tuples can be specified as
parameter or return type of a method.

The full form of ADO is ActiveX Data Object.

DataReader and DataSet are the two fundamental objects in ADO.NET.

Object pooling is a concept of storing a pool (group) of objects in memory that can be reused later as needed.
Whenever, a new object is required to create, an object from the pool can be allocated for this request; thereby,
minimizing the object creation. A pool can also refer to a group of connections and threads. Pooling, therefore, helps in
minimizing the use of system resources, improves system scalability, and performance.

The System.Data.SqlClient namespace.

Datasets follow the disconnected data architecture.

One of the major component of ADO.NET is the DataSet object, which always remains disconnected from the database
and reduces the load on the database.

The IsClosed property is used to check whether a DataReader is closed or opened. This property returns a true value if a
Data Reader is closed, otherwise a false value is returned.

The Fill() method is used to fill the dataset with data.

There must be multiple processes to share the same connection describing the same parameters and security settings.
The connection string must be identical.

OleDbDataAdapter is used to get the data from an Access database.

The Windows Authentication option

The SQL Server Authentication option

Connect Timeout

If you want a control to postback automatically when an event is raised, you need to set the AutoPostBack property of
the control to True.

The ASP.NET 4.0 introduced a new property called View StateMode for the Control class. Now you can enable the view
state to an individual control even if the view state for an ASP.NET page is disabled.

The Data Source property and the Data Member property are used to bind a DataGridView control.

The basic difference between ASP and ASP.NET is that ASP is interpreted; whereas, ASP.NET is compiled. This implies
that since ASP uses VBScript; therefore, when an ASP page is executed, it is interpreted. On the other hand, ASP.NET
uses .NET languages, such as C# and VB.NET, which are compiled to Microsoft Intermediate Language (MSIL).

Page load event guarantees that all controls are fully loaded. Controls are also accessed in Page_Init events but you will
see that view state is not fully loaded during this event

Page object has an "IsPostBack" property, which can be checked to know that is the page posted back.

The System.Web.Ul.Control class is the parent class for all Web server controls.

i)Makes code easy to understand and debug by separating application logic from HTML tags
ii)Provides the isolation of effort between graphic designers and software engineers
iii)Removes the problems of browser incompatibility by providing code files to exist on the Web server and supporting
Web pages to be compiled on demand.

A multilingual Web site serves content in a number of languages. It contains multiple copies for its content and other
resources, such as date and time, in different languages.

Internet Information Services (IIS) is created by Microsoft to provide Internet-based services to ASP.NET Web
applications. It makes your computer to work as a Web server and provides the functionality to develop and deploy
Web applications on the server. IIS handles the request and response cycle on the Web server. It also offers the services
of SMTP and FrontPage server extensions. The SMTP is used to send emails and use FrontPage server extensions to get
the dynamic features of IIS, such as form handler.

You can register a custom server control to a Web page using the @Register directive.

The Session object encapsulates the state of the client and browser.

The globalization is a technique to identify the specific part of a Web application that is different for different languages
and make separate that portion from the core of the Web application. The localization is a procedure of configuring a
Web application to be supported for a specific language or locale.

The ViewState is a feature used by ASP.NET Web page to store the value of a page and its controls just before posting
the page. Once the page is posted, the first task by the page processing is to restore the ViewState to get the values of
the controls.

The Page.Validate() method is used to force all the validation controls to run and to perform validation.

Orientation property of the Menu control sets the horizontal or vertical display of a menu on a Web page. By default,
the orientation is vertical.

Client-side validations take place at the client end with the help of JavaScript and VBScript before the Web page is sent
to the server. On the other hand, server-side validations take place at the server end.

Garbage collection is a heap-management strategy where a run-time component takes responsibility for managing the
lifetime of the memory used by objects. This concept is not new to .NET - Java and many other languages/runtimes have
used garbage collection for some time.

Serialization is the process of converting an object into a stream of bytes.Deserialization is the opposite process, i.e.
creating an object from a stream of bytes. Serialization/Deserialization is mostly used to transport objects (e.g. during
remoting), or to persist objects (e.g. to a file or database).

It's the Attributesproperty, the Add function inside that property.
e.g.btnSubmit.Attributes.Add("onMouseOver","someClientCode();")

Authentication is the process of validating a user on the credentials(username and password) and authorization
performs after authentication. After Authentication a user will be verified for performing the various tasks, It access is
limited it is known as authorization.

The file format used for executable programs and for files to be linked together to form executable programs

.exe

1.These are outbound file.
2.Only one .exe file exists per application.
3..Exe cannot be shared with other applications.

.dll
1.These are inbound file .
2.Many .dll files may exists in one application.
3. .dll can be shared with other applications.

Shadowing is either through scope or through inheritance. Shadowing through inheritance is hiding a method of a base
class and providing a new implementation for the same. This is the default when a derived class writes an
implementation of a method of base class which is not declared as overridden in the base class. This also serves the
purpose of protecting an implementation of a new method against subsequent addition of a method with the same
name in the base class.’shadows’ keyword is recommended although not necessary since it is the default.

An override method provides a new implementation of a member inherited from a base class. The method overridden
by an override declaration is known as the overridden base method. The overridden base method must have the same
signature as the override method.
Use the override modifier to modify a method, a property, an indexer, or an event. You cannot override a non-virtual or
static method. The overridden base method must be virtual, abstract, or override.

Clone - Copies the structure of the DataSet, including all DataTable schemas, relations, and constraints. Does not copy
any data. Copy - Copies both the structure and data for this DataSet.

The .NET Framework provides a run-time environment called the Common Language Runtime, which manages the
execution of code and provides services that make the development process easier. Compilers and tools expose the
runtime's functionality and enable you to write code that benefits from this managed execution environment. Code that
you develop with a language compiler that targets the runtime is called managed code; it benefits from features such as
cross-language integration, cross-language exception handling, enhanced security, versioning and deployment support,
a simplified model for component interaction, and debugging and profiling services.

Assemblies are the building blocks of .NET Framework applications; they form the fundamental unit of deployment,
version control, reuse, activation scoping, and security permissions. An assembly is a collection of types and resources
that are built to work together and form a logical unit of functionality. An assembly provides the common language
runtime with the information it needs to be aware of type implementations. To the runtime, a type does not exist
outside the context of an assembly.

Setting the Expires property to MinValue means that the Cookie never expires.

Windows process is an application that’s running and had been allocated memory in .NET

A delegate acts like a strongly type function pointer. Delegates can invoke the methods that they reference without
making explicit calls to those methods.
