I'm just getting started with App Service web apps. How do I publish my code?

Here are some options for publishing your web app code:

  • Deploy by using Visual Studio. If you have the Visual Studio solution, right-click the web application project, and then select Publish.
  • Deploy by using an FTP client. In the Azure portal, download the publish profile for the web app that you want to deploy your code to. Then, upload the files to \site\wwwroot by using the same publish profile FTP credentials.

For more information, see Deploy your app to App Service.

I see an error message when I try to deploy from Visual Studio. How do I resolve this error?

If you see the following message, you might be using an older version of the SDK:

Error during deployment for resource 'YourResourceName' in resource group 'YourResourceGroup': MissingRegistrationForLocation: The subscription is not registered for the resource type 'components' in the location 'Central US'. Re-register for this provider in order to have access to this location.

To resolve this error, upgrade to the latest SDK. If you see this message and you have the latest SDK, submit a support request.
