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
Common Language Runtime (CLR)
Common Language Infrastructure (CLI)
Common Language Specification (CLS)
.NET Framework tools (examples include gacutil, sn, and all the compilers)
.NET Framework is FREE (including the compilers!)
.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-
User Interface
Web Application Development and
Database Connectivity
Data Access
Network Communications.
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
Console Application
Window Base Application
Web Based Application
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.)
3. LINQ (Language Integrated and Query )
4. Operator overloading- This feature can be abused, but it is still occasionally
useful, especially in libraries and DSLs.
5. Properties- No needs to write getters and setters. Everything looks like a direct
field access, even if it isn’t.
6. Yield CO-Routine capability- This is a powerful and highly useful capability,
especially for lazy iterators.
7. Extension methods- They permit you to “extend” existing classes.
8. 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. We can use pointers, if needed, though unsafe.
On the other hand, VB.NET is developed from VB.
2. Comments in C# are just better. You can do Multiline comments, XML
comments, single line comments, etc.
3. 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
Advance features of C# -
1. LINQ (Language Integrated and Query)-
LINQ to SQL
LINQ to OBJECT
2. XML Web Services
3. 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. It’s 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
