title: .NET find dead code across multiple solutions
body: <p>We have a product with ~15 solutions with each a number of projects.</p>
  
  <p>The question is quite simple: Which tool will enable us to search the entire codebase for dead code? </p>
  
  <p>Searching within a single solution is easy enough (Lots of answers on SO for that one).</p>
  
  <p>But what about determining if "public void Foo()" in project AlphaProj of solution AlphaSol ,which is not used within AlphaSol itself, is actually used in e.g. BetaSol ?</p>
