It would be great if you could find a solution. And please let me know about it

I've just run into this exact issue - deploying Umbraco 10 from Azure DevOps to an Azure App Service - so would love to get some help here.

• Check you are publishing using the correct runtime for your hosting environment? If you are targeting the wrong runtime, you won't even get a log file generated

Where can this be checked?

[UPDATE 1] Having looked through the artifact created at the Build step there's no folder called 'media'

[UPDATE 2] Have confirmed that both local Umbraco project & Azure App Service are targeting .NET 6.0

[UPDATE 3]

For transparency here are the associated pipelines and the wwwRoot contents from the Azure App Service, showing that files have deployed, but it's just not enough:

DeploymentYAML

ReleaseYAML

Contents of wwwRoot

[UPDATE 4]

I've managed to get an ASP.NET Core application deployed just fine, though copying that pipeline exactly doesn't work, so it's an Umbraco-specific setting/problem

[UPDATE 5]

Confirmed that it IS an issue with the missing /media/ folder. Used Azure App Editor, then ran this command (the project is UmbracoBasic01): \> dotnet UmbracoBasic01.dll Unhandled exception. System.IO.DirectoryNotFoundException: C:\home\site\wwwroot\wwwroot\media\ Huge thanks to Rick Butterfield for that direction

[UPDATE 6]

So I'm having a morning where everything just works, so here is the pipeline I've made which seems to not trigger the /media issue. The important part appears to be making sure the pipeline goes through Build->Publish->Deploy phases, which I'm unsure I fully acknowledged before:

trigger:
- master

pool:
  vmImage: 'windows-latest'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'
  # Change webAppName to the name of your Azure App Service web app
  webAppName: 'jacksorjacksorumbcls02azdo'

steps:
- task: NuGetToolInstaller@1

- task: NuGetCommand@2
  inputs:
    restoreSolution: '$(solution)'

- task: VSBuild@1
  inputs:
    solution: '$(solution)'
    msbuildArgs: '/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactStagingDirectory)"'
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: PublishBuildArtifacts@1
  inputs:
    PathtoPublish: '$(Build.ArtifactStagingDirectory)'
    ArtifactName: 'drop'
    publishLocation: 'Container'

- task: AzureRmWebAppDeployment@4
  inputs:
    ConnectionType: 'AzureRM'
    azureSubscription: 'ServiceConnectionMadeInAzDo'
    appType: 'webApp'
    WebAppName: '$(webAppName)'
    packageForLinux: '$(Build.ArtifactStagingDirectory)/**/*.zip'
