ConfigurationExtensions.GetCredentialSettings Method

Returns a CredentialSettings bound from the named credential section. The supplied sectionName is treated as the credential section itself (not a parent client section). The returned settings expose the inline Key (for ApiKey sections) and the resolver-supplied TokenProvider (for token sections, when a resolver matches), so standalone callers can dispatch on either without binding a ClientSettings. Returns null only when the named section does not exist; when the section exists but no resolver claims it, returns a populated CredentialSettings with TokenProvider set to null. Never throws.

Walks the supplied CredentialResolver chain in order (first match wins) against the named credential section and returns a CredentialSettings populated with both the bound metadata (Key, CredentialSource, AdditionalProperties) and the resolver-supplied TokenProvider. The supplied sectionName is treated as the credential section itself. Returns null only when the named section does not exist; when the section exists but no resolver claims it, returns settings with TokenProvider set to null. Never throws.

Applies configureOverrides to a writable overlay of the named credential section, then walks the supplied CredentialResolver chain to populate TokenProvider. Unlike GetClientSettings<T>(IConfiguration, String, IEnumerable<CredentialResolver>, Action<IConfigurationSection>) — which binds the surrounding ClientSettings from the original (non-overlaid) configuration and only feeds the overlay to the resolver chain — the returned CredentialSettings here reflects the post-overlay merged view for Key, CredentialSource, AdditionalProperties, and the Item[String] indexer. The supplied sectionName is treated as the credential section itself. Returns null only when the original section does not exist; overrides cannot synthesize a credential into a missing section. Never throws.
