A source AliasAttribute, GrainTypeAttribute, or GrainInterfaceTypeAttribute specifies a null or empty identity, a value containing a quote, whitespace, a control character, or a reserved type-name delimiter ([](),*&), or an invalid generic arity suffix.
How to fix
Section titled “How to fix”Choose a non-empty identity containing no quotes, whitespace, control characters, or reserved type-name delimiters. Qualified names, nested type names, generic arity suffixes, and literal backslashes retain their meaning. Orleans records valid identities verbatim in the contract manifest.
Write generic arity as a backtick followed by ASCII decimal digits at the end of each nested type name, totaling at most 64. For example, counter`1+Nested`2 is valid; counter`1v2 has text after its arity suffix and must be renamed.
Review identity changes for wire compatibility before deploying them. Attribute constructors and configured type-alias registration enforce the same validity rules at runtime. Follow the identity migration guidance for existing manifests and persisted aliases.
