What's a good way to read config values and secrets?

[intrasight]

I am planning on sharing some dotnet script samples on Github and need to put secrets in a file outside of the repo folder. What are my options?

Since you can source standalone script files, I just made a separate .csx file that contains a class with member variables and I use it like a .env file.

Would environment variables be an option?

You can leverage other library like ConsoleAppFramework which supports many configuration provider in .NET ecosystem. Below is the example:

#r "nuget: ConsoleAppFramework, 4.2.4"
#nullable enable

using ConsoleAppFramework;
using Microsoft.Extensions.Configuration;

string IfSet(string? word, string @default = "") => !string.IsNullOrWhiteSpace(word) ? word : @default;
ConsoleApp.Create(Args.ToArray())
    .AddRootCommand("config", (IConfiguration config, string key) =>
        Console.WriteLine($"The config: {IfSet(config.GetValue<string>(key), "-none-")}"))
    .Run();

PS: by default, it inherits from Host.CreateDefaultBuilder(). As you might guess, it can read from environment variable, json, user secrets by default. You can add more provider if that's your prefer.
