• The word 'Lean' should be 'Learn'.

description: Lean about the .NET Aspire Azure Key Vault integration.

docs/security/azure-security-key-vault-integration.md:33

THe following sections describe various example usages.

• [nitpick] The term ':::no-loc text="Program.cs":::' should be consistent with the rest of the document.

In the :::no-loc text="Program.cs"::: file of your client-consuming project, call the <xref:Microsoft.Extensions.Hosting.AspireKeyVaultExtensions.AddAzureKeyVaultSecrets*> extension method on the <xref:Microsoft.Extensions.Configuration.IConfiguration> to add the secrets as part of your app's configuration.

• [nitpick] The note about AddAzureKeyVaultSecrets API name causing confusion should be clearer.

> [!NOTE]
> The `AddAzureKeyVaultSecrets` API name has caused a bit of confusion. The method is used to configure the `SecretClient` based on the given connection name, and _it's not used_ to add secrets to the configuration.
