Only works on keyvault that have Get, List, Set and Delete AccessPolicies set for you user.
You can create or update individual settings or upload a batch of settings through a Json file
Run the project either in visual studio or do dotnet run in the project root folder.
Then specify the keyvault URL in the interface and click Goto Edit and edit your keyvault.
This is a demo project and should not be used in production environments.
Specificly a : in your Key name will be changed to -- in the keyvault. This so having a keyvault as
source for configuration in a dotnet project it will just work.
