Description

AllowNullLiteralAttribute has a special treatment:

  • FS935 Types with the 'AllowNullLiteral' attribute may only inherit from or implement types which also allow the use of the null literal
  • FS934 Records, union, abbreviations and struct types cannot have the 'AllowNullLiteral' attribute

So we want to keep these special treatment for records and avoid having two errors for the same attribute.

Checklist

  • Test cases added
  • Release notes entry updated
