Deploy .NET 4.7 Application with Azure DevOps

Question

I'm trying to deploy a .NET 4.7 application with Azure DevOps. I pushed the project with Sourcetree and merged these on Azure. Then I've created a pipeline with Azure Repos Git and got a YAML file with the following code:

# ASP.NET
# Build and test ASP.NET projects.
# Add steps that publish symbols, save build artifacts, deploy, and more:
# https://docs.microsoft.com/azure/devops/pipelines/apps/aspnet/build-aspnet-4

trigger:
- master

pool:
  vmImage: 'windows-2022'

variables:
  solution: '**/*.sln'
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

steps:
- task: NuGetToolInstaller@0

- 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: VSTest@2
  inputs:
    platform: '$(buildPlatform)'
    configuration: '$(buildConfiguration)'

- task: PublishBuildArtifacts@1
  displayName: 'Publish artifacts'
  inputs:
    PathtoPublish: $(build.artifactstagingdirectory)
    ArtifactName: 'PublishBuildArtifacts'

Then I've created a release, which worked perfectly. But now I got a Runtime Error, when I open the website. The problem seems to be, that the files don't get compiled. On the FTP server I just see the raw cshtml files.

How can I deploy these files compiled? Do I have to change something in my YAML file? It would be great, if somebody could help me.

Thank you!
