ROSLYN.DESIGN.CA1008 : Enums should have zero value (C#)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

ROSLYN.DESIGN.CA1008 : Enums should have zero value (C#)

Summary

The default value of an uninitialized enumeration, just as other value types, is zero. A nonflags-attributed enumeration should define a member by using the value of zero so that the default value is a valid value of the enumeration. If an enumeration that has the FlagsAttribute attribute applied defines a zero-valued member, its name should be ""None"" to indicate that no values have been set in the enumeration.

This check corresponds to Roslyn rule CA1008. For full rule details, see the Microsoft website: CA1008.
