System.TypeLoadException：无法从程序集“ Microsoft.AspNetCore.Http.Abstractions”中加载类型“ System.Web.HttpUtility”，Version = 3.0.1.0，

Question

我在asp.net core 3.0应用程序中遇到以下错误

System.TypeLoadException: Could not load type 'System.Web.HttpUtility' from assembly 'Microsoft.AspNetCore.Http.Abstractions, Version=3.0.1.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'.

我的应用程序项目文件看起来像是
