- Make optional BitStringFlagsEnum fields nullable (TicketFlags?, S4uOptions?) so .Value access is valid in encode methods - Make CHOICE value-type alternatives nullable (ReadOnlyMemory<byte>?) so HasValue<T>(T?) struct overload is matched correctly - Use wrapper class type for collection references with @cs-class + @cs-name (e.g., METHOD-DATA resolves to KrbMethodData instead of KrbPaData[]) - Use CSharpType nullability instead of IsOptional flag for .Value generation in EmitFieldValueEncode to handle both optional and CHOICE nullable fields - Fix TicketCacheEntry to handle nullable TicketFlags? from KrbCredInfo - Remove invalid AuthorizationData property from DelegationTests (KrbCredInfo has no such field in the ASN.1 spec) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Replaces the old pipeline of 79 XML descriptors + XSLT transform with a modern C# incremental source generator that reads .asn schema files directly. New source generator (Tools/Asn1SourceGenerator/): - ASN.1 tokenizer and recursive descent parser - Type resolver with alias chain following - C# emitter supporting SEQUENCE, CHOICE, InheritedSequence, and CollectionWrapper patterns - Comment-based annotations (@cs-class, @cs-name, @cs-type, @cs-enum, @cs-flags-enum) for C# metadata in .asn files Schema files: - kerberos.asn: Annotated RFC 4120, 4178, 4556 types - kerberos-extensions.asn: FAST, S4U, PAC, KKDCP, IAKerb types Removed: - 79 XML descriptor files - asn.xslt, AsnXml.targets, asn.xsd - 71 .generated.cs files (now generated in-memory by source generator) All 441 tests pass.

Add 98 tests verifying the source-generated API surface matches expectations: - GeneratedApiSurfaceTests: reflection-based verification of type existence, property types/names, enum mappings, nullable correctness, inheritance hierarchy, collection wrappers, and encode/decode method signatures - GeneratedRoundtripTests: pattern-specific encode/decode roundtrips for APPLICATION-tagged sequences, plain sequences, inherited sequences, collection wrappers, CHOICE types, optional field omission, and ENUMERATED enum mapping Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Add 120 unit tests for the ASN.1 source generator components: - TokenizerTests (20): symbol/keyword/number/comment/annotation tokenization, line tracking, peek behavior, error handling - ParserTests (28): module structure, type aliases, SEQUENCE/CHOICE/SEQUENCE OF parsing, tags, OPTIONAL/DEFAULT, imports, annotations, recovery, ENUMERATED - TypeResolverTests (35): class naming, alias resolution, field type mapping, enum/flags-enum annotations, nullable handling, obsolete aliases, alias chains, transparent vs wrapper collections, inherited sequences, CHOICE, tag defaults, cross-module resolution, ToPascalCase utility - EmitterTests (37): all 4 code generation patterns (Sequence, Choice, InheritedSequence, CollectionWrapper), APPLICATION tags, obsolete aliases, optional fields, extensibility, full pipeline smoke tests including real kerberos.asn schema Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Replace all internal usages of source-generator-generated [Obsolete] property aliases with their new canonical names: - KrbKdcRep.EncPart -> EncryptedPart (8 library + 6 test locations) - KrbPriv.EncPart -> EncryptedPart (2 library locations) - KrbEncKrbPrivPart.SeqNumber -> SequenceNumber (1 location) The obsolete aliases remain available for external consumers.

Only declare the explicitReader variable in Decode methods when the type actually has fields with explicit (non-implicit) context-specific tags. Previously it was always declared, causing warnings for types like KrbAlgorithmIdentifier, KrbSubjectPublicKeyInfo, GssapiToken, etc. where all fields use implicit tags.
