Compatibility Issues with Specific NuGet Packages in .NET 7

Question

In my .NET 7 project, I'm encountering compatibility issues with certain NuGet packages. Specifically, an older package is causing compatibility problems with the project target framework. When a package relies on a third-party JSON handler like Newtonsoft.Json instead of internal packages like System.Text.Json, I receive an error.

How can I resolve this compatibility issue in .NET 7? Should I address this by reorganizing package dependencies in the .csproj file or with settings in global.json, or is there an alternative solution? Can Central Package Management, which is used in .NET 7 projects, provide a solution here?

My project was upgraded from .NET 4 to .NET 7. When I run the restore command in the package manager, I encounter compatibility errors. Restarting the project causes version conflicts between dependent packages, and the project fails to build. I manually adjusted package versions using dotnet add package and dotnet restore, but the errors persist. I specified PackageReference settings in the *.csproj file and upgraded packages individually, but conflicts remain within the project.
