| TeamsBotApplication(ApiClient, IHttpContextAccessor, ILogger<TeamsBotApplication>, TeamsBotApplicationOptions, TurnStateLoader) |
Initializes a new TeamsBotApplication without a file downloader. Preserves the exact signature shipped in 2.1.0. C# bakes optional arguments into the CALLER, so an
assembly compiled against 2.1.0 emits a call to this five-parameter form. Without it that call resolves to
nothing at runtime and throws Hidden from IntelliSense because it is a compatibility shim rather than an API to choose. New code should use the constructor that accepts a file downloader. |

TeamsBotApplication(ApiClient, IHttpContextAccessor, ILogger<TeamsBotApplication>, TeamsBotApplicationOptions, TurnStateLoader)
Initializes a new TeamsBotApplication without a file downloader.
Preserves the exact signature shipped in 2.1.0. C# bakes optional arguments into the CALLER, so an
assembly compiled against 2.1.0 emits a call to this five-parameter form. Without it that call resolves to
nothing at runtime and throws MissingMethodException, which recompiling the consuming app cannot fix
when the offending IL is inside a third-party library built against the older version.
Hidden from IntelliSense because it is a compatibility shim rather than an API to choose. New code should use the constructor that accepts a file downloader.
