By default, the isolated worker model uses System.Text.Json for JSON serialization. To customize serializer options or switch to JSON.NET (Newtonsoft.Json), see Customizing JSON serialization.
Logs can be sent to Application Insights from both the Functions host runtime and code in your project. The host.json allows you to configure rules for host logging, but to control logs coming from your code, you need to configure filtering rules as part of your Program.cs. See Managing log levels in the isolated worker model for details on how to filter these logs.
