I was needing to use Mathlink to call some c++ code so I thought I would learn from the basic examples but I am running into strange issue. Following the procedure outlined from the Mathematica Documentation Center I attempted to do the very simple addtwo.exe build. I followed as exactly as I could(since this was written for Visual Studio 2010 some of the names of things weren't exactly the same). When I did the portion where you build addtwo using the Visual Studio Command Line Tools it works great. However, when I try to do the method outlined at "Using the Integrated Development Environment Visual Studio 2010" I get that it isn't able to find the right libraries. And get the following:

1>------ Build started: Project: addtwo, Configuration: Debug Win32 ------
1>addtwo.obj : error LNK2019: unresolved external symbol _MLMain referenced in     function _WinMain@16
1>addtwo.obj : error LNK2019: unresolved external symbol _MLInitializeIcon     referenced in function _WinMain@16
