can we use VisualStudioCredential instead?

// Set the Key Vault URL
string keyVaultUrl = "https://msidlabs.vault.azure.net/";

// Create a new Visual Studio Credential
var credential = new VisualStudioCredential();

// Create a new SecretClient using the Visual Studio Credential
var client = new SecretClient(new Uri(keyVaultUrl), credential);

// Retrieve a secret from Azure Key Vault
KeyVaultSecret secret = client.GetSecret("msidlab1");

Console.WriteLine($"Secret: {secret.Value}");

this will use the Azure Service Authentication account

No, we can't use any of the DefaultAzureCredential options, because there is no option to change the clientID. If you use VSCredentail, it'll use VS clientID.

And VS clientID is not authorized to call MSIDlab.

I was thinking that if we were to directly call the KV that might work though. Maybe not VS client ID, but az cli or some tool might do it

VS clientID is now authorized to call Lab API for an authorized user

should we create a new self signed cert for this purpose? and move away from the SNI cert for lab apps?

It still makes sense to have a single cert secure all our tests apps.

if we move to use Visual Studio credential for DevBox and UAMI based acccess for CI, we do not need this app flow anymore
