2.66.0
(feat): Add a default-timeout-in-seconds config option to the C# SDK generator.
When set, the generated ClientOptions.Timeout defaults to the configured
value (or Timeout.InfiniteTimeSpan when set to "infinity") instead of
the previously hardcoded 30 seconds. SDK users can still override the
timeout per-request via RequestOptions.Timeout.
(feat): Add an opt-in user-agent-name-from-package custom config option. When set
to true, the generated client falls back to a
<NuGetPackageId>/<version> User-Agent header when no
platformHeaders.userAgent is set in the IR (e.g. for SDKs imported from
OpenAPI), matching the TypeScript generator’s npm-package-name fallback.
Defaults to false, preserving the existing behavior of emitting no
User-Agent header in that case.
