What I do

Standardize group join/leave and message broadcast behavior.
Align API persistence + hub push + UI updates.
Reduce reconnect and duplicate-subscription bugs.

Core pattern

Persist chat message in API before broadcasting.
Broadcast to group using canonical event names.
In web client, connect once per active group and clean up handlers on dispose.
Recompute local user identity on reconnect when needed.

Verification

Validate message appears in sender and recipient sessions.
Validate leaving a group stops incoming group messages.
Validate chat history and live updates render consistently.

Working examples from this repo

Hub methods: AspireChat/AspireChat.Api/Hubs/GroupChatHub.cs (JoinGroup, LeaveGroup).
Broadcast event: AspireChat/AspireChat.Api/Chats/SendEndpoint.cs sends ReceiveMessage to Clients.Group(req.GroupId.ToString()).
Client subscription: AspireChat/AspireChat.Web/Services/ChatHubService.cs registers _connection.On<GetAll.Dto>("ReceiveMessage", ...) and joins/leaves groups.
UI integration: AspireChat/AspireChat.Web/Components/Pages/Chat.razor computes IsMe and appends incoming messages in the SignalR callback.
