Study of language features and comparison of VB.NET and C#.

            VB.Net is intended for use with Microsoft Office. C# is the latest release of C++. C# is easier to learn than VB.Net. To learn C#, one should first learn C++. C# is more advanced than VB.Net. C# runs faster than VB.Net. The differences lie in mainly three sections:

·        Syntax

·        Object Oriented features

·        Visual Studio .NET IDE

           

Comparison between C# and VB.NET  

                        C#                                                                                VB.Net

·        Enforces programming rules.                                               Requires “Begin, End”

·        Unsafe Blocks                                                                     Still intended as RAD tool.

·        Documentation Comments                                                 Allows late binding

·        Operator Overloading                                                          VB.NET is slower in execution

Study of .NET framework with comparison of various framework versions.

            .NET framework is an important Windows component that supports the execution of applications created by using various programming languages, such as Visual C#, Visual Basic, Visual F# and Visual C++. The .NET framework consists of a virtual execution system called the CLR and a set of class libraries.

           The .NET Framework is really a cluster of several technologies. These include the following:

      The .NET languages:

 These include Visual Basic, C#, JScript .NET (a server-side version of JavaScript), J# (a Java clone), and C++.

    

       The Common Language Run time (CLR):

This is the engine that executes all .NET programs and provides automatic services for these applications, such as security checking, memory management, and optimization.

    The .NET Framework class library:

 The class library collects thousands of pieces of prebuilt functionality that you can “snap in” to your applications. These features are sometimes organized into technology sets, such as ADO.NET (the technology for creating database applications) and Windows Forms (the technology for creating desktop user interfaces).

    ASP.NET: This is the engine that hosts the web applications you create with .NET, and supports almost any feature from the .NET class library. ASP.NET also includes a set of web-specific services, like secure authentication and data storage.

     Visual Studio: This optional development tool contains a rich set of productivity and debugging features. The Visual Studio setup DVD includes the complete .NET Framework, so you won’t need to download it separately.

            Microsoft released the first version of .NET with the name .NET framework 1.0 in 2002, along with the Visual Studio.NET (2002) Integrated Development Environment (IDE).

            The second revised version of .NET took nearly a year to release and was known as .NET framework 1.1 Microsoft Visual Studio.NET (2003).

            The next version .NET framework 2.0, was released with Visual Studio.NET (2005).NET framework 3.0 formerly called WinFX was released in 2006.

            The next version .NET framework 3.5 was released with Visual Studio.NET (2008).The latest version, .NET framework 4.0 was announced by Microsoft in 2008 and in 2010, the final version of .NET framework 4.0 was released.    

Version	Visual Studio	Default inWindows
1.0	Visual Studio .NET
1.1	Visual Studio .NET 2003	Windows Server 2003
2.0	Visual Studio 2005	Windows Server 2005
3.5	Visual Studio 2008	Windows Vista, Windows Server 2008
4.0	Visual Studio 2010	Windows 7,Windows Server 2008

Database in Asp.net

Asp.net have major parts of database used.Without database,we can not made a dynamic website.There is need to create a dynamic site.

We need to create an component of connection and then needs to open connection and close connection. There is also need these operation in the load page parts.There is also needs to define a query like select,insert,delete etc operation.Query is useful for the execute query using execute query command.

Foreign key used in asp.net

There is used a primary and foreign key used.Primary key as one table information save the same data in the foreign database table.The primary data not unique,and foreign key.

Foreign key set as same key both primary key and foreign key is same,and also set update rule as cascade.Using getdate() give the current time also.We can not change the table information.There is also connect each primary table connect to the foreign key.


Asp.net database have two keys primary and foreign key. Each key are use as  below.The primary key have one identifier.

There is also use inner joint,outer joint,join used.Join means joint two table,each field joint,the common fields.Inner join have left side common,but right side data remove.Outer join have right table field but remove left side field.

Asp.net: CLR

CLR is component of .net Framework.It is execution engie.CLR called runtime in somecase.Source code compiler converted into MSIL code then execute it.

There are different component are given below:

• Class loader
• JIT compiler
• Code Manager
• Garbage collection
• Security engine
• Type checker

NET Framework is an important windows component that supports the execution of application created by using various programming language such as visual C#, Visual Basic, Visual C++.

Common Language runtime( CLR) is one of the most important component of  .NET Framework.

It Supervises the execution of a .NET program by Providing Various properties and controls in the area of memory management, security, and exception handling.

CLR is also called as the execution engine of .NET framework,And also known as RuntimeThe code run on CLR is runcode or manage code.There also provides security.It also managed the array,collection,folder.

NET application is Compiled into MSIL Code( Microsoft Intermediate Language) .MSIL code to Native Code with help of JIT( Just in Time Compiler)Provide the concepts of Managed code and Unmanaged Code.MSIL is a code that consists of CPU and platform independent set of instruction, which can easily converted to native code, also called intermediate language (IL).

An assembly is a logical DLL or EXE, and a manifest is a detailed description (metadata) of an assembly.The .NET compiler produces a portable executable PE file for CLR with the extensions of .exe or .dll.This PE file is mainly comprised of metadata and IL (Intermediate Language).Metadata contains a number of different tables; for example, a type definition table, a filed definition table, a method definition table, and so forth.By parsing these tables, we can get an assembly's types and attributes.
