Microsoft yesterday made available RTM versions of Windows 8 and Microsoft Visual Studio 2012 to TechNet and MSDN subscribers and has also released final version of Microsoft .NET Framework 4.5 to the web.

Many apps on Windows require .NET framework to be installed to run, this framework is also required for developers to build apps .NET 4.5 has more significance with Windows 8 -developers using .NET 4.5 along with Visual Basic or C# programming language can write metro style apps for Windows 8.
