| Category | Maintainability Rules |
A C# code file contains more than one unique type.
A violation of this rule occurs when a C# file contains more than one type. To increase long-term maintainability of the code-base, each type should be placed in its own file, and file names should reflect the name of the type within the file.
It is possible to configure which kind of types this rule should affect. By default, it allows delegates, enums, structs and interfaces to be placed together with a class.
It is also possible to place multiple parts of the same partial type within the same file.
To fix an instance of this violation, move each type into its own file.
