Each day that goes past, the .NET Framework runtime environment becomes an even more important element of the Windows operating systems and the version that will be included in the final release of Windows 8 will be .NET Framework 4.5.
The main importance of .NET Framework 4.5 resides in that it offers programmers a runtime environment for their programs that can work with various programming languages at the same time, thus avoiding having to have a program that is all written in the same language.
The variety of languages supported by .NET Framework 4.5 is very large and completely spans all the main programming languages, among which it is possible to find: C#, C++, Visual Basic .NET, Perl, Python,...
The future of programming for Windows.
The main idea that Microsoft have in mind is to transform .NET Framework into the main application on which all programs developed for Windows will be based, and well as having the added bonus of the implementation of programs for Windows Azure, their platform in the clouds.
Therefore, if you want to see what the new implementation of the runtime environment by Microsoft will include, you only have to download .NET Framework 4.5 free.
