Azure Bot Service and Bot Framework updates for Build 2020

At Build, we had a few announcements across Bot Framework and Azure Bot Service. Bot Framework announcements include: **General Availability of Bot Framework Composer** ([download here](https://dev.botframework.com/)) – a central environment that brings together the key components for chatbot development – including Language Understanding, QnA Maker and Language Generation. Additionally, Composer makes it even simpler to build **Bot Framework Skills,** so that you can build specialist bots that are pluggable components to extend one parent bot. Finally, we also announced a **new Bot Framework SDK V4.9** that makes it even easier to build conversational AI experiences – especially for Teams. For Azure Bot Service, we have simplified the effort required to **support** **human hand-off scenarios** by integrating with popular customer service channels such as LivePerson and Dynamics Omnichannel. Additionally, we have added a new **Alexa channel available in preview**, making it even easier to deploy your chatbots to where your customers are. Please refer to the [Cognitive Services Azure Update](https://azure.microsoft.com/en-us/updates/?query=cognitive%20services) for more on Language Understanding and QnA Maker.
