but above repos are not updated to VS 2022? please any help?

Edit: Looks like other people asks about that issue: https://github.com/dotnet/sdk/issues/1151

Shortly, I need to make a Class Library project can modify/edit in my side only. Other people only use DLL reference or Nuget package.

What I need to do?

1. I need to create a main project that used across me as public source and other people as DLL only not debuggable.
2. In my side the class library project must seen if I choose MSBuild configuration (Debug mode) not Nuget DLL. but I need to modify whole core source. Then republish it again as Nuget to allow other people to use it privately.
3. I guess the whole gape in main project .csproj file. I need to modify it to allow Configuration to switch between Nuget build that visible to other developers and Debug that only visible at me. When choose it the should load and should become visible at my solution.
4. You can ignore Github things I mentioned. A repo can be private/public wihtout problem.

Problem Short Description:

1. I have main project in solution A. (Must be GIT public for other people)
2. I have class library in solution B (Which maybe used in 2 main projects) (Must be GIT private repo for me only)
3. I need the class library source only visible for me not other people. they just see Package or DLL.
4. The main project are public Git repo, while class library are private Git repo.
5. In my case I need to setup a 2 types of MSBuild configuration. (Debug/) and (Nuget/ )
6. the other people only allowed to use which are private nuget package and they must not debug the class library.
7. I need only me to use (Debug/) -> So I can change class library directly and build Nuget package for other people without PDB file,etc included.

What I try to do? What topics I read?
