'*System.Text.Json* unable to load when VisualStudio is not installed

I have a DLL based on netcoreapp3.1. The DLL references the NuGet package Microsoft.Extensions.Configuration.Json version 5.0.0. If I deploy the DLL to another PC where VisualStudio is not installed and try to access it from a third party program, I get the error:

Could not load file or assembly 'System.Text.Json, Version=5.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. Could not find or load a specific file. (0x80131621)

If I install VS on that PC, it works. If I uninstall VS the error appears again.

Apparently VS add some components that are needed for my DLL. How can I resolve that?

Steps I Tried To Resolve

  • I explicitly added the NuGet Package System.Text.Json Version 5.0.2. Error still appears.

Solution 1:[1]

Check dependencies: https://www.nuget.org/packages/Microsoft.Extensions.Configuration.Json/

this version requires for you to use one of:

  • .net framework >= 4.6.1
  • .net standard >= 2.0
  • .net core 5.0

so if you have requirements for netcoreapp3.1 you need to use the version 3.1.20 or lower

for my project when I upgrade .net version from 4.5 to 4.6 it' Ok
