Unresolved External Symbols when trying to use stdio.h functions.

[FaBeyyy]

Im using VS2017, plattform toolset 141, and im getting:

LNK2001 unresolved external symbol ___acrt_iob_func DoubleAgentDll
&
LNK2001 unresolved external symbol ___stdio_common_vfwprintf DoubleAgentDll

when trying to use (VOID)wprintf(); or any other print function after including stdio.h in the DoubleAgentDll.

You need to link against the C Standard Library.

1. Project Properties -> Linker -> General -> Ignore All Default Libraries = Inherit from parent or project defaults
2. Project Properties -> Linker -> Advanced -> Entry Point = Inherit from parent or project defaults

Note that linking against external libraries (except ntdll.dll) might cause problems on some versions of Windows (Specifically Windows 7).
