program.cs文件和ASP.NetCORE 2.0的版本存在一些问题

I have some issues with the program.cs file, with the version of ASP.NetCORE 2.0

这是我的代码

     public class Program
{
    public static void Main(string[] args)
    {
        BuildWebHost(args).Run();
    }

    public static IWebHost BuildWebHost(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseKestrel()
            .UseStartup<Startup>()
            .UseConfiguration(new ConfigurationBuilder().AddCommandLine(args).Build())
            .Build();

}

运行项目时，发生以下错误.

When I run the project, following error occurs.

推荐答案

我在另一个线程中遇到了与此类似的问题，并将我的解决方案发布到了那里:

I had a a similar problem as this in another thread and posted my solution over there: Application Startup Failure with Json read Error. Posting it here as well in case it disappears.

我遇到了同样的问题.就我而言，我将开始实施应用程序的机密，但半途而废.我的secrets.json文件被保留链接，但使用无效的JSON.

I came across the same problem. In my case, I'd started implementing app secrets but left it halfway through. My secrets.json file was left linked but with invalid JSON.

检查您的.csproj以查看是否在<PropertyGroup>下设置了<UserSecretId>属性.如果已设置，除了appsettings.json文件之外，BuildWebHost()还将浏览'%APPDATA%\Microsoft\UserSecrets\{secretId}'中的secrets.json文件.任何一个文件中的错误都会导致该方法失败，但不会告诉您该文件是哪个文件.

Check your .csproj to see if a <UserSecretId> property is set under <PropertyGroup>. If it's set, BuildWebHost() will look through your secrets.json file in '%APPDATA%\Microsoft\UserSecrets\{secretId}', in addition to your appsettings.json file. An error in either file will cause the method to fail, but it won't tell you which file it is.

我的解决方案是删除<UserSecretId>属性或

The solutions in my case were either to remove the <UserSecretId> property or
