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}))*$++`` ---- Namespace foo ' Noncompliant End Namespace ---- == Compliant Solution ---- Namespace Foo ' Compliant End Namespace ----
