Introduction to .NET Technology

.Net Technology is developed by Microsoft in 2000. .Net technology is the new addition to Windows. The .NET ("dot - net") environment is effectively a "virtual computer" that runs on a real computer, through which a developers can create a .NET application in any .NET - compatible language and participate in the same software project writing code in the .NET languages in which (such as Visual C++.NET, Visual Basic .NET, C#, Java, J# and more others).

.NET Core Technology

.NET Technology has quite a few different parts

  1. Common Language Runtime (CLR)
  2. Common Language Infrastructure (CLI)
  3. Common Language Specification (CLS)
  4. .NET Framework tools (examples include gacutil, sn, and all the compilers)
  5. .NET Framework is FREE (including the compilers!)
  6. .NET development is made MUCH easier by using Visual Studio .NET
Introduction of .NET Framework

.NET Framework is a software framework developed by Microsoft for Microsoft Windows operating systems. .NET Framework has a large library, and it supports several programming languages which allows language interoperability (each language can use code written in other languages.)

Features of framework's Base Class Library

  1. User Interface
  2. Web Application Development and
  3. Database Connectivity
  4. Data Access
  5. Network Communications.
  6. Cryptography

The class library is used by programmers, who combine it with their own code to produce applications

Architecture of .NET Framework
History of C#

C#(C Sharp) was designed for developing application in a fully object-oriented manner as part of the Microsoft . NET initiative. C# debuted in the year 2000 by Microsoft founder Bill Gates. At the same time, Visual Studio .NET was announced. C# is an object-oriented programming language as part of their .NET initiative in response to the success of Sun Microsystems' Java programming language.

C# source code—as well as those of other .NET languages—is compiled into an intermediate byte code called MSIL (Microsoft Intermediate Language. C# is primarily derived from the C, C++, and Java programming languages with some features of Microsoft's Visual Basic in the mix. C# is used to develop applications like

  1. Console Application
  2. Window Base Application
  3. Web Based Application
  4. Mobile Application

.NET offers an alternative to Java development. Microsoft's Visual Studio .NET development environment incorporates several different languages including ASP.NET, C#, C++, and J# (Microsoft Java for .NET), all of which compile to the Common Language Runtime.

Why C# is better than other languages

C# and Java- Here are some features that C# has but Java does not

  1. Delegates- You can kind of do this in Java, but it’s not as clean.
  2. Lambdas- Which are way better than anonymous inner classes. (C# has anonymous inner classes, too.) LINQ (Language Integrated and Query )
  3. Operator overloading- This feature can be abused, but it is still occasionally useful, especially in libraries and DSLs.
  4. Properties- No need to write getters and setters. Everything looks like a direct field access, even if it isnÂ’t.
  5. Yield CO-Routine capability- This is a powerful and highly useful capability, especially for lazy iterators.
  6. Extension methods- They permit you to “extend” existing classes.

Null coalescing operator that provides a simple syntax for dereferencing a reference and supplying a default if the reference is null.

C# and VB
  1. C# is a new, type-safe language, object-oriented language. It has automatic garbage collection feature. It is developed solely for running along with CLR frameworks.
  2. We can use pointers, if needed, though unsafe. On the other hand, VB.NET is developed from VB.
  3. Comments in C# are just better. You can do Multiline comments, XML comments, single line comments, etc.
  4. Regions in C# are far better. The key here is that you can place a region inside a function, thus breaking up the implementation into logical pieces.
C# and C++
  1. C++ too complex and unsafe
  2. C++ system-dependent
  3. C++ not Web-ready
  4. C++ does not manage memory
  5. C++ has pointer types
  1. c# nicely improved on Java, VB and C++.
  2. C# can be used for everything like -sockets, threading, events, sql, Â…XML.
  3. C# by Dissection: a plug Parallel treatment
Advance features of C#
  1. LINQ (Language Integrated and Query)
  2. LINQ to SQL


  3. XML Web Services
  4. Cryptography
Most Important Advantages of C#
  1. C# is supported by Microsoft.
  2. C# is type safe which comes with its advantages.
  3. Nothing is better when you are developing windows applications.
  4. Its syntax is also very well designed. Code looks pretty good.
  5. Its intelligence IDE
  6. Its worth learning because lots of code is written and is being written in it.
  7. It feels so good when you code in C# in Visual Studio.
  8. With C# you can explore lots of interesting things .NET,WPF,WCF,XNA,ASP.NET
