C1010: unexpected end of file while looking for precompiled header

fatal error C1010: unexpected end of file while looking for precompiled header. Did you forget to add '#include "pch.h"' to your source?

The project uses a precompiled header, and this file never includes it.

Causes and fixes

1. The file does not include the precompiled header. Add #include "pch.h", or stdafx.h in older projects, as the first line of the file.
2. The file should not use it. For C files and third-party sources, set C/C++ > Precompiled Headers > Precompiled Header to Not Using Precompiled Headers in that file's properties.
3. The name does not match the setting. The include must name the file set in Precompiled Header File, exactly.
