Hi joeccmou,
I'm confused and don't really understand your first problem. If you are getting unresolved symbol errors it sounds like you are not linking to a .lib file.
For the second problem getting exceptions. You are seeing errors being returned from the underlying platform API, in this case WinHttp. They can be caused for a variety of reasons, for example network connectivity. Try catching http_exception instead of std::exception. This is the exception type thrown by the http_client library. On the http_exception class there is a an API http_exception::error_code(). It returns a std::error_code which contains an error code from the OS and an error string with more information.
