No, they don&#x27;t plan to integrate Roslyn and they tend to get a bit cross when people ask. They&#x27;ve been working on their C# code intelligence engine for 10 years in ReSharper, and it does stuff way beyond what Roslyn provides at present. I love Roslyn, and I&#x27;m using it for code analysis stuff, but it&#x27;s not a contender for R# yet.
