title: Build error: "An expression is too long or complex to compile"
body: <p>Every now and then when I build a specific solution, I'll get a random amount of "An expression is too long or complex to compile" in the Error List window. However, the only item the error points to is the specific project, not a file within the project or a specific LOC.</p>
  
  <p>When I encounter this, I 'Clean' and then I restart VS and that seems to fix it. Any ideas on what is causing this?</p>
  
  <p>This particular solution has 50 projects in it.</p>
