Can't Access Azure Key Vault from desktop console app

Question

I am having trouble accessing a secret from an Azure key vault. I suspect the problem is that I don\'t adequately understand the terminology, so the arguments I\'m supplying

Answer 1

Mark's blog was extremely helpful, from that blog I learnt how to do it and below are the steps and code as of 6-Nov-2018.

Summary of the steps:

1. Register App
2. Create Key inside this newly registered App
3. Create Key Vault and Assign permission to the app
4. Create Secret inside the vault

Access them thru code

using Microsoft.Azure.KeyVault;
using Microsoft.IdentityModel.Clients.ActiveDirectory;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace Experiments.AzureKeyValut
{
    internal class AzureKeyValueDemo
    {
        private static async Task Main(string[] args)
        {
            await GetSecretAsync("https://YOURVAULTNAME.vault.azure.net/", "YourSecretKey");
        }

        private static async Task GetSecretAsync(string vaultUrl, string vaultKey)
        {
            var client = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(GetAccessTokenAsync), new HttpClient());
            var secret = await client.GetSecretAsync(vaultUrl, vaultKey);

            return secret.Value;
        }

        private static async Task GetAccessTokenAsync(string authority, string resource, string scope)
        {
            //DEMO ONLY
            //Storing ApplicationId and Key in code is bad idea :)
            var appCredentials = new ClientCredential("YourApplicationId", "YourApplicationKey");
            var context = new AuthenticationContext(authority, TokenCache.DefaultShared);

            var result = await context.AcquireTokenAsync(resource, appCredentials);

            return result.AccessToken;
        }
    }
}
