2.65.0
(feat): Generate CONTRIBUTING.md for C# SDKs, matching the pattern used by the TypeScript generator.
The file is skipped for whitelabel SDKs.
2.64.2
(fix): Dedup auth-derived headers in the generated client constructor when
multiple auth schemes resolve to the same HTTP header name (for
example, an oauth2 bearer scheme plus an apiKey-in-header scheme
both named Authorization). Previously the constructor’s
Dictionary<string, string> collection initializer added the same
key twice and threw System.ArgumentException: An item with the same key has already been added at runtime. Earlier auth schemes
win, preserving the ordering established by the IR.
(fix): Fix literal boolean auth-header values being emitted as "True" regardless
of the configured value. The generated client constructor’s auth-header
dictionary tested the truthiness of the Literal discriminated-union
object instead of reading its boolean field, so a literal false header
incorrectly produced "True".
