Deployment slot has empty contents for Azure App Service

I recently set up deployment slots for my apps for Blue/Green deployment. I created a second slot for a staging environment. The new deployment slot has it's own URL. When clicking on this URL, it seems to have no content.

As per documentation from Microsoft (https://learn.microsoft.com/en-us/azure/app-service/deploy-staging-slots?tabs=portal) "The new deployment slot has no content, even if you clone the settings from a different slot". This seems to be normal behaviour.

Now I am confused, then what is the point of the deployment slot. Just for pre-configuring parameters? I know you can have slot specific environment variables.

Would the only way for me to see my updated app be to perform the swap, take a look, and if there's bugs, I would swap back?

Yes, as mentioned in the MSDoc, the new Deployment slot adds only the configuration settings.

• Only the default page will be displayed, Even I got the same.

• You can deploy new set/different version of code to the created slot.
• To test the staging slot, you need to deploy the code to that particular slot.

• If you want to check the same code, select the same code and deploy again to the staging slot.

• In Visual Studio you can see the Deployment Slots.

• You can see the 2 publish profiles.
