即时尝试将RC1项目迁移到RC2。我的项目恢复并建设成功。但是，当我输入dotnet运行我得到异常：找不到方法：'Microsoft.Extensions.Configuration.IConfigurationBuilder Microsoft.Extensions.Configuration.IConfigurationBuilder.Add（Microsoft.Extensions.Configuration.IConfigurationProvider）'。dotnet运行 - MissingMethodException
这是我启动的构造：
public Startup(IHostingEnvironment env)
{
Log.Logger = new LoggerConfiguration().MinimumLevel.Debug().
WriteTo.RollingFile(@"C:\log\file-{Date}.txt",
outputTemplate:
"{Timestamp: yyyy-MM-dd HH:mm:ss.fff zzz} {Level}:{EventId} [{SourceContext}] {Message}{NewLine}{Exception}")
.CreateLogger();
var builder = new ConfigurationBuilder() //<-error in this line
.SetBasePath(env.ContentRootPath)
.AddJsonFile("appsettings.json")
.AddJsonFile("config.json")
.AddEnvironmentVariables();
Configuration = builder.Build();
}
这是我project.json：
