title: Debugging fluent validation rules
body: <h1>The problem</h1>
  <p>I'm struggling to make my Fluent Validation RuleSet work, currently it doesn't, and I don't have any idea why is that happening, everything seems all right. I would like to somehow step into the code that performs the validation itself, but RuleSet lambdas are ExpressionTrees which doesn't provide even poor debugging experience.</p>
  <h1>The question</h1>
  <p>Is there a way to debug RuleSet logic to see what's happening inside RuleSets?</p>
