== Why is this an issue? Sharing some naming conventions is a key point to make it possible for a team to efficiently collaborate. This rule allows to check that all class 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. BackColor * Short abbreviations of 2 letters can be capitalized, e.g. GetID * Longer abbreviations need to be lower cased, e.g. GetHtml === Noncompliant code example With the default regular expression ``++^([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?$++``: [source,vbnet] ---- Class foo ' Noncompliant End Class ---- === Compliant solution [source,vbnet] ---- Class Foo ' Compliant End Class ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) === Message Rename this class to match the regular expression: "xxx". === Parameters .format **** _STRING_ ---- ^([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?$ ---- Regular expression used to check the class names against. **** ''' == Comments And Links (visible only on this page) include::../comments-and-links.adoc[] endif::env-github,rspecator-view[]
