Azure: deploy multiple websites from a single solution

A typically used scenario is to have a solution with two or more web apps. This might be a website project followed by one or more Web API projects.

1. Create a Resource Group.
2. Add a Web App for each website being deployed.
3. For each web app –
   1. Within Application Settings for each web-app add a new setting:
      1. Name: PROJECT
      2. Value: [foldername]/[projectname].csproj
   2. Configure a deployment strategy, for example; using Github

When you commit your code (or your chosen deployment strategy is triggered) all the Azure web apps will deploy their respective projects.
