Exception usage analyzer

Over a year ago I wrote a blog post about designing exceptions. I found this article very useful by myself and I used it as a reference a few times during code review. However, it’s almost impossible to expect that, after reading the recommended resource, anybody would start to apply described rules immediately and remember about them all the time. It’s a learning process and it takes some time. A while ago I got interested with Roslyn (I even delivered a public presentation about it - polish recording available here) and there is a really cool thing about Roslyn analyzers that can solve this problem - they help to actively introduce best practices into your codebase.
