C# coding style: comments

Question

Most C# style guides recommend against the /* ... */ commenting style, in favor of // or ///. Why is the former style to be avoided?

Answer 1

One example that comes to mind is that it's possible to accidentally interrupt a /* style comment. For example

/* This is the start of a comment that documents the 
   behavior of the +-*/ operators in our program
*/ 

This code does not compile, while the // variant would. Also the /// represents a specific style of documentation to which external tools respond differently.
