1.11.0 (2026-05-05)

Features Added

• Added CredentialResolver abstract class — an extensibility hook that lets credential providers participate in the configuration-driven credential resolution pipeline. Resolvers are invoked in registration order until one produces an AuthenticationTokenProvider for a given configuration section.
• Added IConfiguration.GetCredential(...) extension overloads on ConfigurationExtensions that walk a chain of CredentialResolver instances against a named credential section, with optional configureOverrides to mutate the section in-flight.
• Added IConfiguration.GetClientSettings<T>(...) extension overloads that bind a ClientSettings-derived type and resolve its Credential via the resolver chain.
• Added AddCredentialResolver<T> extension methods on IServiceCollection and IHostApplicationBuilder that register a CredentialResolver once per implementation type (idempotent).
• The DI AddClient<TClient, TSettings> / AddKeyedClient<TClient, TSettings> paths now auto-resolve credentials from the registered resolver chain, so callers no longer need to wire up provider-specific helpers like WithAzureCredential explicitly when a resolver is registered.
• Resolving the same credential section more than once returns the same AuthenticationTokenProvider instance.

Breaking Changes

• IClientBuilder no longer inherits from IHostApplicationBuilder. The internal ClientBuilder implementation now uses composition instead of inheritance. PostConfigure return type changed from IHostApplicationBuilder to IClientBuilder. AddClient and AddKeyedClient continue to return IClientBuilder.
