Remarks
This registers:
-
IHttpClientFactoryviaAddHttpClient()— used internally by the SDK for outbound HTTP calls (e.g., Bot Connector, token endpoints). - MVC Controllers via
AddControllers()— required for ASP.NET authorization services.
AddHttpClient() is idempotent and registers a default IHttpClientFactory. If you need named or typed clients (e.g., for custom DelegatingHandler pipelines or specific timeouts), register them separately via builder.Services.AddHttpClient("name", ...) — this does not conflict with the default registration.
If you need full control over HTTP client configuration for SDK internals, skip this method and use ServiceCollectionExtensions directly to register services manually.
