title: Changing from "Any CPU" to "X64"
body: <p>Previously, our software had to be created for both 32bit and 64bit Windows. Now, product management decided that we do not need to support 32bit Windows anymore (that's great with regard to third party SDKs and drivers).</p>
  
  <p>In almost all of our some 200 projects, the DEBUG and RELEASE configurations have the "Platform target" of "Any CPU" only (only some wrappers of third party components are specialized). Of course, the software will run on 64bit systems with such settings. 
  But compiling for 64bit only could allow for more compiler optimizations (or am I mistaken?), so I'd prefer to create 64bit executables.</p>
  
  <p>As shown in <a href="https://stackoverflow.com/q/3155492/1263436">How do I specify the platform for MSBuild?</a> , there is no possibility to simply add a parameter to the msbuild command line, instead every project has to be changed...</p>
  
  <p>What's the easiest way to do so? Or do I not need to care because there's no advantage in doing so?</p>
  
  <p>Note: we use C# with Visual Studio Professional 2015 Version 14.0.25425.01 Update 3.</p>
