title: Import a C++ .lib and .h file into a C# project?
body: <p>I have just started a C# project and want to import a C++ .lib and it's corresponding header (.h) file. </p>
  
  <p>I've read various posts that all mention .dll, rather than .lib, which is confusing me. </p>
  
  <p>The image below shows the .lib and .h file I'm referring to, all I've done is drag them into the project.</p>

  <p>Can anyone point me to a clearer explanation of how to go about doing this? I'm sure it can't be as hard as it seems. </p>
