Issue: Multiple levels Json Deserialization with System.Text.Json.JsonSerializer API

[Sandeep321]

A couple of issues with the current implementation of Serialization/DeSerialization:

1. We need to specify the JsonSerializerOptions everywhere we do the DeSerialization. It makes migration of existing projects to .Net core 3.1.0 very tricky and cumbersome. I really wonder if it's worth that much refactors. There is a workaround to fix it in one place but it would be nice if that comes from the .Net core team.
2. Next is even if I use the correct JsonSerializerOptions for DeSerialization, first-level properties get deserialized correctly but not the next level complex JSON objects. It works all fine with Newtonsoft JSON. This could be related to this Issue

Are these known issues and do we have any workaround for these?

There's an issue to be able to specify the serializer's global options: #31094. This will solve the issue of specifying the options everywhere.

Populating collections without setters is currently not supported. There's an issue tracking this: #30258.

I'll close this as a duplicate. @Sandeep321 in the future, please create different issues for different concerns so we can properly track issues.
