Newtonsoft.Json.dll conflict after ecs package imported

[kxingking]

UnityVersion: 2019.3.2f1
Create an empty project and import quicksheet package,it works fine.But when I import Unity ECS package from package manager, error message showed:

PrecompiledAssemblyException: Multiple precompiled assemblies with the same name Newtonsoft.Json.dll included for the current platform. Only one assembly with the same name is allowed per platform. Assembly paths: Assets/QuickSheet/GDataPlugin/Editor/Google/Newtonsoft.Json.dll, {ProjectPath}/Library/PackageCache/[email protected]/Runtime/Newtonsoft.Json.dll

I delete the dll file at :Assets/QuickSheet/GDataPlugin/Editor/Google/Newtonsoft.Json.dll,and fixed code error in GoogleDataSettingsEditor.cs by using JsonUtility.

After I press “Finish Authentication" button, an error dialog showed , got the error message:

Could not load file or assembly "Newtonsoft.json,version =4.0.5.0,Culture=neutral,PublickKeyToken=30ad4fe6baeed" or one of its dependcies"

What show I do?

Thanks for ur excellent work.

Thank to the post on How to reference Newtonsoft.json without conflicts?, I change newtonsoft.json dependcy version to 2.0.0-preview in the package manifest file and delete the one in QuickSheet/GDataPlugin/Editor/Google folder.

After that I found this issue is same as the issue #77,so I close this issue .
