Hi friends, in
this article I am posting some interview Questions VB.NET and .NET Framework and i explained the interview questions in the previous articles Interview Questions on ASP.NET,VB.NET and SQL Server and ASP.NET Page Life Cycle Events || What is the sequence in which ASP.NET events are processed? Interview Questions on ASP.NET All the Best Friend.
2.What is the base
class of .NET?
1.What is VB.NET?
Visual Basic .NET (VB.NET), is an object-oriented computer programming
language .
VB.Net is windows based programming
language. It supports OOP concepts such as
System.Object
3.What is the difference between
early binding and late binding
Early binding - Assigning values to variables during design time or exposing object model at design time.
Early binding - Assigning values to variables during design time or exposing object model at design time.
Late Binding - Late binding has the
same effect as early binding. The difference is that you bind the object
library in code at run-time
Calling a non-virtual method, decided
at a compile time is known as early binding. Calling a virtual method (Pure
Polymorphism), decided at a runtime is known as late binding.
4.What’s the difference between
private and shared assembly?
Assemblies are two types
1.private
2.public or shared
A Private assembly is used by a single
application, and it is stored in the application's directory, or a sub
directory beneath it.
A shared assembly is normally stored in
Global Assembly Cache, which is a repository of assemblies maintained by .NET
run time.
Private assembly is used inside an
application only and does not have to be identified by a strong name.
Shared assembly can be used by multiple
applications and has to have a strong name.
Private assembly is specific to the
application. By adding the assembly in bin folder, we can access the assembly
only in that application.
Shared assembly is shared by all
applications, which are hosted in the machine. By adding the assembly to Global
Assembly Cache(GAC), we can access the assembly in all applications hosted in
that machine.
5.What is Commom Language Runtime?
CLR also known as Common Language Run time provides a environment in
which program is executed, it activate object, perform security check on them,
lay them out in the memory, execute them and garbage collect them.
The Common Language Runtime (CLR) is an Execution Environment . It works
as a layer between Operating Systems and the applications written in .Net
languages that conforms to the Common Language Specification (CLS). The main
function of Common Language Runtime (CLR) is to convert the Managed Code into
native code and then execute the Program. The Managed Code compiled only when
it needed, that is it converts the appropriate instructions when each function
is called. The Common Language Runtime (CLR) 's Just In Time (JIT) compilation
converts Intermediate Language (MSIL) to native code on demand at application
run time.
