Answer 1

You need to set dependency in release mode also. Rightclick on project->click on Property->c++->Additional Include Directories and write the name of dlls in both release and debug mode.

Answer 2

You are creating implicitly linked library, exporting only. This will work for explicit linkage.

For implicit linking, you have to import symbols (functions) to your application.
