v4.6.0

Welcome to the 4.6 release of the Bot Framework SDK for .NET!

Bot Framework SDK for Microsoft Teams (GA)

The Bot Framework SDK v4.6 release fully integrates support for building Teams bots allowing users to use them in channel or group chat conversations. By adding a bot to a team or chat, all users of the conversation can take advantage of the bot functionality right in the conversation.

Bot Framework SDK Skills (Preview)

Create a reusable conversational skill to add functionality to a bot. Leverage pre-built skills, such as Calendar, Email, Task, Point of Interest, Automotive, Weather and News skills. Skills include language models, dialogs, QnA, and integration code delivered to customize and extend as required.

Adaptive Dialog (Preview)

Adaptive Dialogs enable developers to build conversations that can be dynamically changed as the conversation progresses. It allows developers to dynamically update conversation flow based on context and events. This is especially handy when dealing with conversation context switches and interruptions in the middle of a conversation.

Language Generation (Preview)

Language Generation enables developers to separate logic used to generate bot's respones including ability to define multiple variations on a phrase, execute simple expressions based on context, refer to conversational memory.

Common Expression Language (Preview)

Common Expression Language allows you to evaluate the outcome of a condition-based logic at runtime information. We provide a common language that can be used across the Bot Framework SDK and conversational AI components, such as Adaptive Dialogs and Language Generation.
