Bing Location Control for Microsoft Bot Framework

Overview

The Bing location control for Microsoft Bot Framework makes the process of collecting and validating the user's desired location in a conversation easy and reliable. The control is available for C# and Node.js and works consistently across all channels supported by Bot Framework.

Use Case and Features

Bots often need the user's location to complete a task. For example, a Taxi bot requires the user's pickup and destination address before requesting a ride. Similarly, a Pizza bot must know the user's delivery address to submit the order, and so on. Normally, bot developers need to use a combination of location or place APIs, and have their bots engage in a multi-turn dialog with users to get their desired location and subsequently validate it. The development steps are usually complicated and error-prone.

The Bing location control makes this process easy by abstracting away the tedious coding steps to let the user pick a location and reliably validate it. The control offers the following capabilities:

• Address look up and validation using Bing's Maps REST services.
• User location returned as strongly-typed object complying with schema.org.
• Address disambiguation when more than one address is found.
• Support for declaring required location fields.
• Support for FB Messenger's location picker GUI dialog.
• Open-source code (C# and Node.js) with customizable dialog strings.

Prerequisites

To start using the control, you need to obtain a Bing Maps API subscription key. You can sign up to get a free key with up to 10,000 transactions per month in Azure Portal.

Getting Started

Navigate to the C# or Node.js folder and follow the guide to add the control to your Bot Framework bot.
