About Programming

1. The Future of Development

2. .NET is a major technology change for Microsoft and the software world. Just like
the computer world moved from DOS to Windows, now they are moving to .NET. But
don't be surprised if you find anyone saying that "I do not like .NET and I would stick
with the good old COM and C++". There are still lot of people who like to use the
bullock-cart instead of the latest Honda car.

3. .NET technology was introduced by Microsoft, to catch the market from the SUN's Java. Few
years back, Microsoft had only VC++ and VB to compete with Java, but Java was catching the
market very fast. With the world depending more and more the Internet/Web and java related
tools becoming the best choice for the web applications, Microsoft seemed to be loosing the
battle. Thousands of programmers moved to java from VC++ and VB. This was alarming for
Microsoft and many of the Microsoft fan's kept on asking "is Microsoft sleeping?". And
Microsoft had the answer. One fine morning, they announced : "We are not sleeping. We have
the answer for you.". And that answer was .NET.

4. But Microsoft has a wonderful history of starting late but catching up quickly. This is true in case
of .NET too. Microsoft put their best men at work for a secret project called Next Generation
Windows Services (NGWS)., under the direct supervision of Mr. Bill Gates. The outcome of the
project is what we now know as .NET. Even though .NET has borrowed most of it's ideas from
Sun's J2EE, it has really outperformed their competitors.

22. Is these all things are Free
YES
Need a Licensed Windows OS

23. MS .NET Visual Studio Express Edition
Its Free and Perfect For Beginner in DOTNET

24. MS .NET Visual Studio Professional Edition
Its Not Free Protease

26. Base Class Library
Or
Framework Class Library

27. Framework Class Library
The .NET Framework class library is a library of classes, interfaces, and value types that provide
access to system functionality. It is the foundation on which .NET Framework applications,
components, and controls are built. The namespaces and namespace categories in the class
library are listed in the following table and documented in detail in this reference. The
namespaces and categories are listed by usage, with the most frequently used namespaces
appearing first.

28. Framework Class Library
Input Output Operation Windows Messages
String Handling Database Management
Managing Array Evaluation of Mathematic Function
Access Files and Folders Drawing
Access Registry Managing Errors
Security Connecting Internet And XML
Windowing Many, Many, Many, More

30. Framework Class Library Advantages
1. Language Independents
2. Completely Object Oriented
3. Fully Extensible
4. Packed In Form of DLL
5. Well Optimized Performance

31. Learn the Programming Language Syntax and
Base Class Library Remain Same

32. Namespace
1. A Namespace is Logical Collection of Classes and other Types with Unique
Name
2. The Structure of the Namespace is like a tree where all the related Class Are
Like Leaves
3. Base Class Library Began With “SYSTEM”

33. Versions of DOTNET

34. Versions and Version Dependency
Version 1.0 in Year 2002  Standalone
Version 1.1 in Year 2003  Standalone
Version 2.0 in Year 2005  Standalone
Version 3.0 in Year 2006  Over .NET 2.0
Version 3.5 in Year 2007  Over .NET 3.0
Version 4.0 in Year 2010  Standalone
Version 4.5 in Year 2012  Replace 4.0
All Versions Can Be Installed Side By Side on Same Machine

35. Version Compatibility
Doesn't Support Backward and Forward Compatibility
The Version of Development Machine and Production Machine Must Be Same

41. The compilers of CLS-compliant languages compile the source code and generate an
intermediate code, called MSIL code, and metadata. MSIL Code contains a CPU independent set
of instructions, which describes how to load, store, initialize, and call. They also contains
instructions to perform arithmetic and logical operations, access memory directly, control the
flow of execution, handle exceptions and perform other operations. methods on objects

42. Before you execute the MSIL code, you need to compile it into CPU-specific instructions. To
execute the code, the runtime requires information about the code that is in the metadata. The
metadata describes the code and defines the types that the code contains as well as references
to other types that the code uses at run time. MSIL Code and metadata both located in the .PE
(portable executable) file.

43. Portable Executable in .NET
When we execute .PE file, the class loader loads the MSIL code and metadata from the portable
executable file into the run-time memory.

44. Demo by Showing the MSIL Code on DOTNET
Application

45. Calling Entry Point
After the MSIL code and metadata are loaded into the memory, the code manager
calls the entry point method, which is Main, Win Main or DllMain method. An entry-
point method is the first method to be executed when you run your application.

46. The Garbage collector performs periodic checks on the managed heap to identify the
objects that are no longer required by the program and removes them from memory.
Garbage Collection in .NET

47. The applications running within the common language runtime can utilize the
managed multithreading support. The .NET Framework allows a single process to be
divided into one or more sub processes called application domains. Each application
domain can contain one or more threads. The runtime monitors all the threads that
have executed code within its process .
Managed Multithreading support

48. The common language runtime also allows managed code to interoperate with
unmanaged code. One of the components of the common language runtime is the
COM marshaler, which performs marshaling of data when data passes between
managed and unmanaged execution environments.
Interoperate With Unmanaged Code

49. Then with the help of JIT the IL code is converted into Native code or we can say
Intermediate set of instructions are converted into CPU set of instruction.
