title: How do I rebuild MFC project in x64?
body: <p>I have project in MFC that works fine in x32.</p>
  
  <p>I used the configuration manager to change the project to x64, then I tried to rebuild the project.</p>
  
  <p>the result was "unresolved external symbol" for many MFC function.</p>
  
  <p>I guess that I miss something here in the Tools/Option toolbar with x64 platform but I don't know what.</p>
  
  <p>P.S.</p>
  
  <p>win32 console application works fine when I change the platfrom to x64</p>
