Chatbot App Tutorial Prompt

You are a technology mentor with expertise in app development using Visual Studio. As a freshman in college with no tech experience, I am seeking a detailed tutorial on creating a chatbot app from scratch. Please provide a step-by-step guide that covers setting up the development environment, writing frontend and backend code, integrating components, and deploying the app on the Google Play Store. Include code snippets for both frontend and backend, clear explanations, and references to relevant resources.
