Answer 1

I have Created and Published Web app Service in Azure , it Worked fine for me. please follow the below steps to resolve your issue.

1. Go to the Azure Portal .
2. Click on App Services.
3. Click on your application service.
4. Click on Configuration -->Application settings.
5. Click Add new setting, and add the following entry: Name: WEBSITE_WEBDEPLOY_USE_SCM , Value: false

6. Click on Save and close the Application settings window.

7. Click on your application service.

8. Download the publish profile by clicking on Get publish profile.

9. Import the publish profile when publishing your application service to Azure from Visual Studio.

This disables SCM and enables you to publish your application service to Azure.

Answer 2

I tried this solution earlier, but this didn't work in my case, this was actually due to partially deleted publish profile under the properties folder. So completely clearing (leaving launchSettings.json intact) that and adding profile again helped me resolve this issue.
