 # Universal CRT deployment
 
 From Visual Studio .NET through Visual Studio 2013, each major release of the C++ compiler and tools has included a new, standalone version of the Microsoft C Runtime (CRT) library. These standalone versions of the CRT were independent from, and to various degrees, incompatible with each other. For example, the CRT library used by Visual Studio 2012 was version 11, named msvcr110.dll, and the CRT used by Visual Studio 2013 was version 12, named msvcr120.dll. Beginning in Visual Studio 2015, it's no longer the case. Visual Studio 2015 and later versions of Visual Studio all use one Universal CRT.

It's available for older operating systems, Windows Vista through Windows 8.1, by using Windows Update. Local deployment of the Universal CRT is supported, with some restrictions.
