using Keyvalult in local machine

Question

After configuring the Azure Key Vault and publishing my app, the application is working properly from the website. However, when i tried to run it on my local machine using VS2019 debugger, I am getting the following error. However, if I comment out the "ConfigureAppConfiguration()" method, I am able to run the application on my local machine.

I am guessing that i am supposed to maybe save the "vaultUri" somewhere in my code. Any pointers is greatly appreciated.

Thanks in advance,
Samuel

Hello @Samuel Tilakraj ,

Thanks for reaching out.

There is similar question was asked from this thread, sharing here for your reference.

Here is screenshot of when I configure Azure Key Vault through Connected Services from visual studio . To know more about how "Safe storage of app secrets in development in ASP.NET Core works".

Hope this helps.
