Call C standard library function from asm in Visual Studio

Question

I have a problem with calling C function from asm project created in visual studio (Win10 x64, Visual Studio 2015). Project consist of one asm file:

.586
.model flat, stdcall
option casemap:none
includelib msvcrt.lib

ExitProcess PROTO return:DWORD
extern printf:near

.data
text BYTE "Text", 0

.code
main PROC
    push offset text
    call printf
    add esp,4
    invoke ExitProcess,0
main ENDP
end main

When I build project, linker outputs the error:

Error LNK2019 unresolved external symbol _printf referenced in function _main@0

Linker output parameters:

/OUT:"C:\Users\apple\Documents\SP_Lab7\Debug\SP_Lab7_Demo.exe" /MANIFEST:NO /NXCOMPAT /PDB:"C:\Users\apple\Documents\SP_Lab7\Debug\SP_Lab7_Demo.pdb" /DYNAMICBASE "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" /MACHINE:X86 /SAFESEH:NO /INCREMENTAL:NO /PGD:"C:\Users\apple\Documents\SP_Lab7\Debug\SP_Lab7_Demo.pgd" /SUBSYSTEM:WINDOWS /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /ManifestFile:"Debug\SP_Lab7_Demo.exe.intermediate.manifest" /ERRORREPORT:PROMPT /NOLOGO /TLBID:1

If I comment call print, then everything executes normally (even Windows API function). Is there any way to call C function from asm file without creating cpp file that includes <cstdio>? Is it possible to do?

Microsoft refactored much of the C runtime and libraries in VS 2015. Some functions are no longer exported from the C library (some are defined in a C header file). Microsoft has some compatibility libraries like legacy_stdio_definitions.lib and legacy_stdio_wide_specifiers.lib, but you can also choose to use the older Visual Studio 2013 platform toolset with the older C libraries.

To change the platform toolset: pull down the Project menu; select Properties...; go to Configuration Properties/General, and change Platform Toolset to Visual Studio 2013 (v120)
