I need a fully-functional AI receptionist built in pure C#. The application must continuously read incoming direct messages from the major social networks, interpret the intent, reply in natural language—either as plain text or synthesized voice—and, when appropriate, secure an appointment for the sender. Core requirements • Social inbox monitoring: poll or stream the APIs of Facebook, Twitter and Instagram and whatsapp (and leave the code structured so additional channels can be plugged in later). • Natural-language understanding: leverage an LLM or service such as Azure OpenAI, then drive the conversation flow according to my configurable rules. • Voice layer: integrate Microsoft Cognitive Services (or a comparable .NET-friendly engine) so replies can be spoken as well as typed. • Appointment handling: once the user confirms a time, the bot must write straight to my Microsoft 365 calendar; if that API is unavailable it should fall back to sending a confirmation email. • Admin dashboard: WinForms, WPF or Blazor—your choice—as long as I can see message logs, override replies and tweak intents without touching code. Deliverables 1. Complete Visual Studio solution with clean, documented C# source. 2. Step-by-step setup notes covering API keys, webhook endpoints and any Azure resources. 3. A short screen-capture demo showing the bot replying in both modalities and creating a live calendar event. Acceptance will be based on a 15-minute test session in which I send sample messages from each social platform, hear a spoken acknowledgment and receive an appointment in my calendar.

Hi, I am Adeel. I built MyHeartLine, a voice AI product that holds natural conversations, summarises them and pushes updates to family members by email and SMS. That is the same conversation and notification loop you need here. For this I would use Azure OpenAI for intent and reply generation, Azure Cognitive Services for the voice layer, and Microsoft Graph for calendar writes with email fallback. I would start with WhatsApp and one social channel first, then extend the plumbing to the rest. Given the budget, I would phase it: core WhatsApp plus calendar and voice first, then Facebook and Instagram inboxes after. Which single channel matters most to you to get working first?

Managing messages from multiple social platforms while keeping every conversation natural and prompt can feel overwhelming, especially when just one missed appointment means lost business and frustrated clients. Juggling inbox streams, deciphering intent, and confirming bookings across Facebook, Instagram, Twitter and WhatsApp demands both precision and flexibility—and it eats up valuable time. You can expect a single C# AI receptionist that never misses a direct message, replies just like you would, and automatically creates appointments in your Microsoft 365 calendar, so you stay organized without lifting a finger. First, I’ll build a Visual Studio solution that plugs into each social inbox and connects to Azure OpenAI for intent and flow. Then, I’ll add a smooth voice integration using Microsoft Cognitive Services for both text and spoken replies. Finally, I’ll create an admin dashboard so you can see logs, override responses, and update rules easily. Which social channel do you find most challenging to manage right now?

Hi, there. "C# AI RECEPTIONIST AUTOMATION" - you need one C# service that can unify social messages, AI intent handling, voice replies and appointment booking into a controllable workflow. I can structure the solution in ASP.NET Core/C#, with separate channel adapters for Facebook, Instagram, X and WhatsApp so additional channels can be added without changing the core conversation logic. Azure OpenAI can handle intent and response generation, while configurable rules control when the AI replies, escalates or books an appointment. Microsoft Graph would handle Microsoft 365 calendar creation, with email fallback when required. I would use Blazor for the admin dashboard so logs, overrides and intent rules remain easy to manage. Can you provide the API access/details for the social channels and confirm whether Microsoft 365 Graph access is already available? Looking forward to working with you.

Hello, I can develop a C#/.NET-based AI receptionist that can handle incoming calls or messages, understand customer requests, provide relevant information, schedule appointments, capture leads, and integrate with your existing business systems. With 20 years of software development experience, I can work with C#, .NET, AI/LLM APIs, speech-to-text/text-to-speech, REST APIs, databases, and telephony integrations. A few quick questions: - Should the AI receptionist handle phone calls, chat, or both? - Which telephony/CRM/calendar systems need to be integrated? - Do you already have conversation flows and business FAQs, or should these be designed? I’ll focus on natural conversations, reliable automation, secure data handling, appointment workflows, and clear fallback to human staff when needed. I’m available to start immediately. Thanks

Hello, I can build this AI receptionist as a clean C#/.NET solution, with a modular architecture so additional messaging channels can be added without rewriting the core conversation engine. I’ll integrate the supported Facebook, Instagram, X/Twitter, and WhatsApp APIs, route incoming messages through Azure OpenAI with configurable intents/rules, and provide both natural-language text and Microsoft Cognitive Services voice responses. For appointments, I’ll integrate Microsoft Graph with Microsoft 365 Calendar, including a reliable email fallback when calendar creation is unavailable. I’ll also build a practical Blazor/WPF admin dashboard for message logs, reply overrides, intent/rule management, and configuration. The solution will include secure API configuration, webhook/API setup documentation, clean commented C# source, and a short demonstration covering conversation, voice response, and live calendar creation. I’ll design the components for reliability, logging, error handling, and future channel expansion. Looking forward to work with you. Thanks

Hi there, I see you need an AI receptionist built purely in C# that can handle social inbox monitoring and integrate with Microsoft services. To achieve this, I would utilize the APIs of Facebook, Twitter, Instagram, and WhatsApp to handle incoming messages. The natural language understanding component can leverage Azure OpenAI to guide the conversation flow effectively. For the voice layer, integrating Microsoft Cognitive Services will allow synthesized responses, while handling appointments directly with Microsoft 365 calendar can be achieved using its API. I will ensure the application includes a user-friendly admin dashboard—I'm comfortable with WinForms, WPF, or Blazor, depending on what suits your needs best. I'll also provide a complete Visual Studio solution, setup notes, and a demo to showcase functionality. Regards, Ali

Hello, I am Ankit from Manama. C# is the easy half. Your 15-minute test depends on access: Meta app review for Messenger and Instagram, a WhatsApp Business number, and paid X API access for DMs. You need: - one inbox for all four channels, open to more later - text or voice replies, booked into Microsoft 365 My approach: 1. One channel end to end, with calendar and email fallback. 2. Other channels and the Blazor dashboard. 3. Test, record the demo, hand over. It confirms the time before booking, never guesses. I build .NET applications. I can start now. Three things worth confirming: 1. Are your Meta and WhatsApp Business accounts approved? 2. Voice replies sent as audio messages in the chat? 3. Is the X API paid tier acceptable? Let us discuss in chat. Thank you. Ankit

Hi, Fernando here from Mexico. I want to build the C# AI receptionist around reliable social inbox handling, Azure OpenAI conversation logic, voice responses, and Microsoft 365 appointment creation. I’d use ASP.NET Core with a channel adapter structure so Facebook, Instagram, WhatsApp, and Twitter remain isolated and new channels can be added without changing the conversation engine. I’ve built API driven AI systems where model output is grounded in application data and controlled before reaching users. I’ll start with one complete message-to-appointment flow and make it reviewable before adding the remaining channels and admin controls. Bests Fernando Garcia
