Depends on what parts, entire products of the Sql server product line are in C#, like Sql Server Reporting Services for instance.

The core sql server rdbms engine is hosting the .net runtime for a few things - but there its maginal compared to C++.

Exact. It's marginal. Saying "written in .net" about sql server made the Microsoft PFEs laugh during our coffee break though.
