推荐答案

该错误与您的项目无关.错误消息很明显"表明Microsoft.NET.Sdk.Publish.Tasks.TransformAppSettings.TransformAppSettingsInternal()试图访问Newtonsoft.Json.显然这不是您的代码.

The error has nothing to do with your project. The error message "clearly" says that Microsoft.NET.Sdk.Publish.Tasks.TransformAppSettings.TransformAppSettingsInternal() tried to access Newtonsoft.Json. This is obviously not your code.

我发现这很奇怪，因为Microsoft.NET.Sdk.Publish.Tasks.dll与Newtonsoft.Json.dll位于同一目录中(请检查c:\ program files \ dotnet \ sdk)，并且应该针对出厂时的相同版本进行编译.您可以使用ILSpy之类的东西进行确认，以查看Newtonsoft.Json的程序集版本是什么以及发布任务dll具有哪个程序集引用.您还可以使用Fusion Logs更好地了解.NET用于尝试加载dll的路径和dll，以及为何未使用具有匹配文件名的任何dll.但是我不会在这里写关于使用融合日志的教程.

I find this very strange, as Microsoft.NET.Sdk.Publish.Tasks.dll exists in the same directory as Newtonsoft.Json.dll (check c:\program files\dotnet\sdk), and it should have been compiled against the same version that ships. You can confirm using something like ILSpy to see what the assembly version of Newtonsoft.Json is and what assembly reference the publish tasks dll has. You can also better understand the paths and dlls that .NET used to try to load the dll, and why any dll with a matching filename was not used, using Fusion Logs. But I'm not going to write a tutorial on using Fusion Logs here.

无论如何，了解它发生的原因并不能帮助您解决它.您真正可以做的就是确保使用的是最新的SDK，如果没有，请安装最新版本，如果问题仍然存在，请使用Visual Studio报告问题"工具让.NET Core团队了解这一点.

In any case, understanding why it's happening won't help you solve it. All you can really do is make sure you're using the latest SDK, install the newest version if not, and if the problem still exists using the Visual Studio "report a problem" tool to let the .NET Core team know about this.
