Bot Framework for dotnet

This repository contains code for the .NET version of the Microsoft Bot Framework SDK, which is part of the Microsoft Bot Framework - a comprehensive framework for building enterprise-grade conversational AI experiences.

This SDK enables developers to model conversation and build sophisticated bot applications using .NET. SDKs for JavaScript, Python and Java (preview) are also available.

To get started building bots using the SDK, see the Azure Bot Service Documentation.

Dependency Graph

To view our libraries' interdependencies, you can refer to the dependency graph for our libraries.

Getting Started

To get started building bots using the SDK, see the Azure Bot Service Documentation.

The Bot Framework Samples includes a rich set of samples repository.

If you want to debug an issue, would like to contribute, or understand how the Bot Builder SDK works, instructions for building and testing the SDK are below.



Clone a copy of the repo:

git clone

Change to the SDK's directory:

cd botbuilder-dotnet

Build and test locally

Open Microsoft.Bot.Builder.sln in Visual Studio. On the menu bar, choose Build > Build Solution.

When the solution is built, local NuGet package files (.nupkg) are generated for each project and are available under the outputPackages directory. You can add this folder to your NuGet Package Manager source list in Visual Studio (choose Tools > NuGet Package Manager > Package Manager Settings from the Visual Studio menu and add an additional Package Sources from there), allowing you to consume these in your local projects.
