Method AddOnnxChat

Namespace

Qavren.Edge.Chat

Assembly

Qavren.Edge.Chat.Onnx.dll

AddOnnxChat(EdgeBuilder, ChatPreset, Action<EdgeChatOptions>?, Action<ChatClientBuilder>?)

Calls AddOnnx() (so sub-project 2's order-200 OrtEnv task, model paths, resource monitor and model store are present and correctly ordered), registers the device profile, the model host, the provisioner, the order-400 startup task, the lifecycle observer and the diagnostics contributor, then delegates to services.AddChatClient.

Registration goes through MEAI's own AddChatClient and not a hand-rolled IChatClient descriptor, because that is the descriptor Agent Framework and Semantic Kernel resolve, and because its factory is ChatClientBuilder.Build - so the pipeline is constructed lazily from the app's provider and the order of builder calls does not matter. AddChatClient and AddKeyedChatClient live in the Microsoft.Extensions.DependencyInjection namespace, not Microsoft.Extensions.AI (plan adjustment 10).

Returns EdgeBuilder rather than ChatClientBuilder, matching AddOnnxEmbeddings and the rest of the suite's chaining idiom; the MEAI pipeline is the optional pipeline callback. Remember MEAI's ordering contract: ChatClientBuilder.Build applies factories in REVERSE, so the FIRST Use() call is the OUTERMOST client.
