Why `Directory.GetCurrentDirectory()` doesn't work in `InProcess` hosting model

I am trying to accessing the appsettings.json file in the Main method of the Program class as follows:

public static void Main(string[] args)
 {
                IConfiguration configuration = new ConfigurationBuilder()
                    .SetBasePath(Directory.GetCurrentDirectory())
                    .AddJsonFile("appsettings.json").Build();

                string connectionString = configuration.GetConnectionString("DefaultConnection");
}

It works fine without InProcess hosting model but does not work in InProcess model and throws the following error:

The configuration file ‘appsettings.json’ was not found and is not optional. The physical path is ‘C:\Program Files\IIS Express\appsettings.json’.

Now my questions are:

1. Why Directory.GetCurrentDirectory() doesn’t work in InProcess hosting model?
2. What is the alternative solution to this to access the appsettings.json when using InProcess hosting model.

Thank you!

@jkotalik Please tell me how shall I use this in place of Directory.GetCurrentDirectory() in the above code. Thank you.

I changed to:

public static IConfiguration Configuration { get; } = new ConfigurationBuilder()
            .SetBasePath(AppContext.BaseDirectory)
            .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
            .AddJsonFile($"appsettings.{Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT") ?? "Production"}.json", optional: true)
            .AddEnvironmentVariables()
            .Build();

Hi @jkotalik

Is hostingContext.HostingEnvironment.ContentRootPath more appropriate here rather than: Directory.GetCurrentDirectory()?

Or is this a new feature in the patch which you are referring to?
