library_names

The library name '{0}' isn't a lower_case_with_underscores identifier.

The analyzer produces this diagnostic when the name of a library doesn't use the lower_case_with_underscores naming convention.

The following code produces this diagnostic because the library name libraryName isn't a lower_case_with_underscores identifier:

library libraryName;

If the library name is not required, then remove the library name:

library;

If the library name is required, then convert it to use the lower_case_with_underscores naming convention:

library library_name;
