== Why is this an issue? Shared coding conventions allow teams to collaborate efficiently. This rule checks that all namespace names match a provided regular expression. The default configuration is the one recommended by Microsoft: * Pascal casing, starting with an upper case character, e.g. Microsoft, System * Short abbreviations of 2 letters can be capitalized, e.g. System.IO * Longer abbreviations need to be lower cased === Noncompliant code example With the default regular expression: ``++^([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?(\.([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2}))*$++`` [source,vbnet] ---- Namespace foo ' Noncompliant End Namespace ---- === Compliant solution [source,vbnet] ---- Namespace Foo ' Compliant End Namespace ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) === Message Rename this namespace to match the regular expression "rrr". === Parameters .format **** ---- ^([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?(\.([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2}))*$ ---- Regular expression used to check the namespace names against. **** endif::env-github,rspecator-view[]
