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 interface names match a provided regular expression.

The default configuration is the one recommended by Microsoft:

• Must start with an upper case 'I' character, e.g. IFoo
• Followed by Pascal casing, starting with an upper case character, e.g. IEnumerable
• Short abbreviations of 2 letters can be capitalized, e.g. IFooID
• Longer abbreviations need to be lower cased, e.g. IFooHtml

Noncompliant code example

With the default regular expression ^I([A-Z]{1,3}[a-z0-9]+)*([A-Z]{2})?$:

Interface Foo  ' Noncompliant
End Interface

Compliant solution

Interface IFoo ' Compliant
End Interface
