Playing around with Caliburn project and see my teammate wrote cref Attribute in a function comment:

 /// <summary>
/// Initializes a new instance of the <see cref=”AdministerEmployeeView”/> class.
/// </summary>

This xml documentation syntax looks totally new to me.
MSDN explanation, cref = Code reference.  It specifies that the inner text of the tag is a code element, such as a type, method, or property.

I think is worth to spend some time to go through XML Documentation Cross-References.
