Azure has Static Web Apps functionality integrated with Blazor now, but only works with GitHub as the source repository for the preview version. This article has a great description of how to get it working. It appears that the Azure Static Web Apps functionality really streamlines the process for building CI/CD for these types of applications. And supports a Blazor WebAssembly frontend connected to Azure Functions for the service ends. This is the exact design we use for the SimpleRPG game.
As we showed in the SimpleRPG game tutorial, we can also host Blazor WebAssembly apps in Azure Storage accounts exposed as static web site.
When Azure Static Web Apps supports integration with Azure DevOps repositories, we will update the game tutorial to deploy using this mechanism as well.
