@Harshi Patel Can you please provide more details like how are you trying to access Key Vault - user account, by an application ?
Have you given proper permissions to user/application using Azure Key Vault Access policies ?
For that, go to the Azure Portal and access the KeyVault to which you are going to give access and look for the Access policies blade:

From here you will be able to select what access should he have, either by a template:

Please make sure that this has been completed for the user, once this has been done and after about 15 replication minutes it should be possible for the user to access the KeyVault contents.

I have the exact same issue

reproductive code:

var cred = new VisualStudioCredential();
_client = new SecretClient(new Uri("https://jdpkeyvault.vault.azure.net/"), cred);
string value = _client.GetSecret("MongoConnectionString").Value.Value;

Having the same 403 error when debugging an asp.net core project, to get a secret from key vault.

PS: Already choose the correct account in "vs options - azure service authentication", and add the account with enough permissions in key vault access policies.

The code:
string uri = "key vault url";
SecretClient client = new SecretClient(new Uri(uri), new DefaultAzureCredential());
Response<KeyVaultSecret> secret = await client.GetSecretAsync("kv-sec-test"); //throw the error here

nuget package:
<ItemGroup>
<PackageReference Include="Azure.Identity" Version="1.3.0" />
<PackageReference Include="Azure.Security.KeyVault.Secrets" Version="4.1.0" />
</ItemGroup>

Looks like it has bugs on DefaultAzureCredential class, especially the VisualStudioCredential class being used internally. According to https://learn.microsoft.com/en-us/dotnet/api/overview/azure/identity-readme, I replaced the DefaultAzureCredential with ChainedTokenCredential, the key value secret was successfully retrieved.

Sample code:
var cred = new ChainedTokenCredential(new ManagedIdentityCredential(), new AzureCliCredential());
SecretClient client = new SecretClient(new Uri(keyvaultUri), cred);
Response<KeyVaultSecret> secret = await client.GetSecretAsync("kv-sec-test");

For using AzureCliCredential, login with azure cli is required. The details can be found in above link.

I had this same error message when trying to deploy a Cloud Service (Extended Support) which tied the web role to a key vault. I was able to solve the issue by upgrading Visual Studio from 16.9.2 to 16.9.6. This may relate to more key vault access issues than the one I was having and hope this helps someone else out.

Access denied to first party service.
