How to get connection string out of Azure KeyVault?

Question

A hypothetical web-site currently connects using:

public SqlConnection CreateConnection()
{
   DbConnection connection = new SqlConnection();
   connection.Conne         


        

Answer 1

For .net Core and already having Azure Key Vault in place. Now it's extremely easy. Let's assume your connection string is in your appsettings.json:

{
   "ConnectionStrings": {
      "MyDatabase": "server=127.0.0.1;port=5678;database=mydb;user=FullMontyBurns;password=hunter2"
   } 
}

And you do your setup in Startup.cs:

string connectionString = configuration.GetConnectionString("MyDatabase");

In Azure Key Vault, create a secret:

• Name: ConnectionStrings--MyDatabase
• Value: server=127.0.0.1;port=5678;database=mydb;user=FullMontyBurns;password=hunter2

The IConfiguration.GetConnectionString("MyDatabase") now takes the value from the Key Vault.
