Microsoft .NET enhances the computing experience with highly integrated communications and information.

Microsoft .NET helps to get the most of client's existing technology investments while creating new ways to implement powerful, cost-effective information technology that will meet future needs.

Microsoft .NET delivers substantial savings in the development costs and creates new revenue streams, through the use of XML Web services.

C #
C# is a modern, a new model for developing applications, the use of emerging web standards, an object-oriented language that enables programmers to quickly build a wide range of applications for the new Microsoft .NET platform which provides tools and services that fully exploit both computing and communications. C# is a great choice for developing a wide range of components from high-level business objects to system-level applications. Using simple C# language constructs these components can be converted into Web services allowing them to be invoked across the Internet from any language running on any operating system.

The use of emerging Web standards like Hypertext Markup Language (HTML), Extensible Markup Language (XML) and Simple Object Access Protocol (SOAP). Existing development tools were developed before the Internet or when the Web as we know it today was in its infancy. As a result, they don't always provide the best fit for working with new Web technologies.

C# programmers can leverage an extensive framework for Building Applications on the Microsoft .NET platform. C# includes built-in support to turn any component into an XML Web service that can be invoked over the Internet-from any application running on any platform.

There are more subtle features that make C# a great Internet programming tool. For instance, XML is emerging as the standard way to pass structured data across the Internet. Such data sets are often very small. For improved performance, C# allows the XML data to be mapped directly into a struct data type instead of a class. This is a more efficient way to handle small amounts of data.

VB.Net
Visual Basic has always been a flagship language for Microsoft and this didn't change. Visual Basic .NET 1.0 remained a featured language for Microsoft development in the new .NET world although the new languages J# and C# were announced at the same time.

Perhaps the most talked about change is the addition of two major new object-oriented tricks: inheritance and overloading. For me, inheritance is nice but I don't expect to use it very often. On the other hand, I really like overloading and can't wait to make full use of it.

The real power of the new VB.NET is in the fact that it has full access to the .NET Base Class Library. The .NET Base Class Library (BCL) consists of several thousand classes and other data types (such as interfaces, structures and enumerations) that are divided into about 90 namespaces. In fact, the VB .NET language itself is implemented as a set of classes belonging to the Microsoft.VisualBasic namespace. (The C# and JScript languages are also implemented as a set of classes in corresponding namespaces.) For the most part, we don't need to use the classes in the Microsoft.VisualBasic namespace directly because VB wraps them up for us nicely. In fact, VB .NET can be defined largely as a wrapper for the classes in the Microsoft.VisualBasic namespace.

ColdFusion
ColdFusion is a powerful server-side scripting language that allows users to interact with databases to produce dynamic pages. ColdFusion is a tag-based language and very easy to learn to use but also a powerful programming environment. The ColdFusion is a rapid application development system used to create interactive Web sites and perform the server-side processing. The Web application can be executed from a Web page or over the Web. The Web Applications Servers are data driven accept the Data from users through forms and connect to databases. The Web Application Server uses the web pages to display data to the end-users.

Feature of ColdFusion
Generates and retrieves email using SMTP/POP
ODBC- complaint are used as a data source
Provides hundreds of functions
Supports expressions in queries, including Regular expressions
Provides extensive number of tags
Supports COM and DCOM objects
Includes its own API called CFAPI
Includes file management capabilities
Integrates with Lightweight Directory Access Protocol (LDAP) servers
Can be managed and administered from any Web Browser anywhere.

ColdFusion to create dynamic web pages and it is one of the emerging server side programming tools for the web. Thus the server-based application makes developing and deploying reliable, robust and ensures high performance of Web Applications and interactive Web sites. This is to ensure that Web is incredibly easy to create and used for both the end-users and developers.
