Technical Summary: PromptSpark.Chat PromptSpark.Chat is a real-time conversational workflow application built on ASP.NET Core that guides users through structured multi-step processes using adaptive cards and SignalR for bidirectional communication. The application enables dynamic workflow execution with branching logic, interactive UI elements powered by Microsoft Adaptive Cards, and optional AI integration (via chat completion services) to handle questions beyond predefined workflows. The architecture employs server-side conversation state persistence using thread-safe ConcurrentDictionary for continuity across page refreshes, minimal concurrency overhead, and flexible workflow definitions via JSON configuration files, allowing workflows to be easily customized without code changes. Built with a modern tech stack including C# (31.4%), SCSS (29.9%), HTML (28.5%), and JavaScript (9.1%), the application demonstrates responsive frontend design paired with backend real-time capabilities, making it suitable for guided customer interactions, onboarding flows, multi-step form processing, and intelligent chatbot scenarios. The project is positioned as a technical demonstration within the Make Bold Spark portfolio, authored by Mark Hazleton, and provides a practical example of integrating SignalR, Adaptive Cards, and optional AI services within an ASP.NET Core framework—though notably the repository shows no recent activity and zero stars, suggesting it may be early-stage or primarily for educational purposes.
