c, Visual Studio will use the C compiler (and not the C++ compiler) to compile them. As long as your source code file names all end in. This workaround works because the default behavior of Visual Studio is to compile source code files that have a “.c” file name extension as C, and to compile files that have a. c before you press the button that actually creates the new file. The workaround involves adding a new C++ file to your project, but changing the filename’s extension from. A workaround is required to create a new C project. The New Project Wizard in modern versions of Microsoft Visual Studio does not contain templates that explicitly create C projects - all of the C-type templates specify C++ as the programming language (see the following picture). This seems counter-intuitive, but the C++ component includes both the C compiler and the C++ compiler. To compile C programs with Microsoft Visual Studio, you must have the C++ component installed.

If you wish to use C++, see Building a Microsoft Visual Studio C++ Project for Your c-tree Application. This document is for compiling projects using C.
