How does the application know to use the updated secret within HashiCorp Vault?

We have a .NET application and are working towards a config provider. The problem is that I don’t understand how the application is going to use a static KV/KV2 secret that was manually updated. I was thinking polling might address this but any tips are appreciated.

Just to keep it in mind:

Are you using Consul as storage backend?

Is this a duplicate to your former question? How does the application integrated with hashicorp pull the latest static secret that was updated in vault?

For Consul as storage backend this could be a solution
