Managed to detect the offending code, removing it from my .razor makes livesharp work

@if (_connection?.State != HubConnectionState.Connected)
{
    <p>
        Status:
        <label data-toggle="tooltip" data-placement="top" title="@ConnectionId">
            @(_connection?.State.ToString() ?? "Connecting")
        </label>

    </p>
}
