Installation

Available via NuGet package Bot.Builder.Community.Middleware.HandleActivityType

Install into your project using the following command in the package manager;

    PM> Install-Package Bot.Builder.Community.Middleware.HandleActivityType

Usage

To use the middleware, add it to the pipeline:

middleware.Add(new HandleActivityTypeMiddleware(ActivityTypes.ConversationUpdate, async (context, next) =>
                    {
                        // here you can do whatever you want to respond to the activity
                        await context.SendActivity("Hi! Welcome. I am the bot :)");

                        // If you want to continue routing through the pipeline to additional
                        // middleware and to the bot itself then call the following line.
                        await next();
                    }));

You can also use the middleware to simply filter out activity types you do not wish your bot to handle at all

middleware.Add(new HandleActivityTypeMiddleware(ActivityTypes.ConversationUpdate, async (context, next) => { }));
