Build Succeeded, but no .lib file gets created

.lib will not get generated if you miss to add prefix __declspec(dllexport) for methods.

Open the Project Properties (right-click the project in Solution Explorer, select 'Properties'). Under 'Librarian', check 'Output File' - that's where the output should go.

If this looks right, try dir /s *.lib in a suitable subdirectory for your project, to see if you can locate the output library by date and time. If you still can't find it, try a clean rebuild (right click project, select 'Rebuild').

For DLLs, a .Lib file is not created if the DLL exports nothing for external usage. I don't think this applies for static lib builds but I would make sure you are exporting something public from your library project source code.

My static library contains nothing but two template classes, so I didn't have a .cpp file. This caused Visual Studio 2015 to not output a .lib file. To solve this, I made a file huh.cpp which includes all of the headers.

I had the same problem, even though I was already using the __declspec(dllexport) function.

Your ProjectName.cpp file needs to #include "ProjectName.h". If you don't include the header file then the functions don't get exported. The DLL builds fine, no errors or warnings (at least in VS2017 15.8), but you don't get a LIB file.

Include the header and boom - LIB file is generated. A rookie mistake I'm sure, but everyone has to start learning somewhere.
