title: Compile child process and copy binaries
body: <p>Currently I have a project A (64 bit) that references projects B, C, and D (all 32 bit). And I set <code>Copy Local = True</code>, such that all projects are compiled and the binaries are copied to the <code>bin</code> folder of project A. The binaries <code>B.exe</code>, <code>C.exe</code> and <code>D.exe</code> all run as a child process of <code>A.exe</code>. However Visual Studio complains with:</p>
  
  <blockquote>
    <p>There was a mismatch between the processor architecture of the project being built "AMD64" and the processor architecture of the reference 'project B' "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.</p>

  <p>Should I just ignore the warning? Or should I just post build events to build and copy the other projects? What is the best approach?</p>
