Microsoft Corporation has decided to make a huge change with Visual Studio 11 Express. Visual Studio 11 Express will prevent developers from building apps that are not Metro. Metro is a user interface that is seen in the Windows Phone operating system and it involves using screen tiles for navigation. After Visual Studio 11 Express is rolled out, either developers will be stuck with Metro or they can spend $500 to buy Visual Studio 11 Professional to get around having to develop Metro apps. Previously developers were able to build desktop applications on Visual C++ 2010 Express and Visual C# 2010 Express. Microsoft will be removing the compiler toolchain from the Windows SDK for Windows 8 to prevent backdoor coding.
