The .NET is the technology from Microsoft, on which all other Microsoft technologies will be depending on in future. It is a major technology change, 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 on 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. To recover the .market, .Microsoft announced .NET.

Microsoft’s VC++ was a powerful tool. But it was too complex. It has too many data types, and developers had to learn many libraries including Windows SDK, MFC, ATL, COM etc. There were many data type compatibility issues while exchanging data between different layers. Visual Basic was too easy, and many serious programmers hated it just for that reason. Even though Visual basic was very easy to use, it was not very flexible to develop serious applications. SUN’s Java became a very good choice for these reasons. It had the flexibility and power of C++ and at the same time easy enough to catch the attention of VB programmers.
Microsoft recognized these factors and they introduced the .NET considering all these factors. All unwanted complexities are eliminated and a pure object oriented programming model was introduced. This makes programmer’s life very easy.
.NET is said to be Microsoft development model in which software becomes platform and device independent and data becomes available over the internet. Due to this vision Microsoft .NET is also called Microsoft strategy for connecting systems, information and devices through web services so people can collaborate and communicates effectively.
