DevExpress WPF AI Chat Control

AIChatControl embeds a ready-made, Copilot-style chat interface in your WPF app. The conversation flow (user messages, streaming assistant responses, Markdown rendering, file attachments, prompt suggestions, history) is built in — you supply an IChatClient (Azure OpenAI / OpenAI / Ollama / Semantic Kernel) and drop the control on a ThemedWindow. Under the hood it hosts the DevExpress Blazor DxAIChat component inside a BlazorWebView.

This skill covers project setup, installing the NuGet, registering an AI client, placing the control, and the basic features (streaming, Markdown, file upload, prompt suggestions, history, manual message handling).

• Render Markdown / code blocks in chat messages
• Let users attach files (PDF / images / text) to chat messages
• Persist and reload chat history (SaveMessages / LoadMessages)
• Manually intercept messages (MessageSending) — for guard rails, side channels, custom AI calls
• Display multiple chat surfaces with different AI services (ChatClientServiceKey)
