我正在使用Swashbuckle.AspNetCore软件包来记录我的API。在开始对某些类进行JSON序列化之前，我已经使用了数周。现在我在Swagger用户界面中出现错误：
"Failed to load API definition" - Fetch error Internal Server Error /swagger/v1/swagger.json
我的日志文件显示以下错误：
System.IO.FileLoadException：无法加载文件或程序集 'Newtonsoft.Json，版本= 1.2.0.0.0，文化=中性， PublicKeyToken = 30ad4fe6b2a6aeed”。找到的程序集清单 定义与程序集引用不匹配。 （来自的例外 HRESULT：0x80131040）
我更新到Newtonsoft.Json v12.0.1。 Swagger NuGet软件包是否依赖于Newtonsoft的早期版本？
我尝试更新整个解决方案以使用Newtonsoft.Json v12.0.1。 我还搜索了Swagger与Newtonsoft可能存在的任何依赖关系，但是我没有看到任何明确的内容。

我希望招摇的页面像往常一样列出我的HTTP方法。
