Hi hkbeer,
According to your description ,I’m not sure which way you used to deploy your app to azure.
About how to deploy your app to azure ,you could refer to the following link, there has several ways to do it.
https://docs.microsoft.com/en-us/azure/app-service-web/web-sites-deploy
In your case, for example, if you used FTP to upload file , you could connect to FTP by host name , account and password, and then copy the changed files to FTP(if the aspx.cs file also changed ,you could copy the assembly of the web site to FTP too).
If you have any other questions, please feel free to contact me any time.
Best Regards
Even
