@live1206 @tadelesh @srnagar I thought the plan here was to make sure this decorator would also work for Java. Based off of the name of the decorator, it still seems to be csharp specific

yeah made the same comment on the old PR #1230 (comment)

My opinion is that either

1. this is a very specific csharp decorator like the name implies here and tghen we should not add scope and put in a CSharp sub namespace
2. Make it generic enough that other language might use it and then use the scoping system

This decorator does not fit the usage for Java, please check https://teams.microsoft.com/l/message/19:meeting_MGQ4YTVhYTYtZWU1OC00NzI4LWEzYzktMjgzYzg3OTBkY2Q5@thread.v2/1723169831963?context=%7B%22contextType%22%3A%22chat%22%7D

I raised the concern of csharp specific decorator, but we decided to go in root namespace and default to all scopes during the previous discussion, please check https://teams.microsoft.com/l/message/19:meeting_MGQ4YTVhYTYtZWU1OC00NzI4LWEzYzktMjgzYzg3OTBkY2Q5@thread.v2/1723177908738?context=%7B%22contextType%22%3A%22chat%22%7D
