title: What is the actual impact of choosing ".NET" as "Active Solution Platform"?
body: <p>I would like to understand the real implications of choosing the ".NET" as the "Active Solution Platform" on a Visual Studio 2010 solution.</p>

  <p>For each project listed on my solution I have the available options as Platform target: "Any CPU" or "x86". So I'm not sure what does the ".NET" option, as a solution-wide setting means. </p>
