Question

我正在尝试在.net核心控制台应用程序中添加ConfigurationBuilder 运行以下代码时出现此异常。我检查并在Directory.GetCurrentDirectory()中找到文件appsettings.json。

System.IO.FileNotFoundException
  HResult=0x80070002
  Message=Could not load file or assembly 'Microsoft.Extensions.FileProviders.Physical, Version=2.2.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.
  Source=Microsoft.Extensions.Configuration.FileExtensions
  StackTrace:
   at Microsoft.Extensions.Configuration.FileConfigurationExtensions.SetBasePath(IConfigurationBuilder builder, String basePath)
   at DashboardService.Program.Main(String[] args)

var builder = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json");
