A section of the Xml header documentation for a C# element does not end with a period (also known as a full stop).
C# syntax provides a mechanism for inserting documentation for classes and elements directly into the code, through the use of Xml documentation headers. For an introduction to these headers and a description of the header syntax, see the following article: http://msdn.microsoft.com/en-us/magazine/cc302121.aspx.
A violation of this rule occurs when part of the documentation does not end with a period. For example, the summary text in the documentation below does not end with a period:
/// Joins a first name and a last name together into a single string
/// <param name="firstName">The first name.</param>
/// <param name="lastName">The last name.</param>/// <returns>The joined names.</returns>
public string JoinNames(string firstName, string lastName)
How to Fix Violations
To fix a violation of this rule, ensure that all sections of the documentation end with a period.
