Azure DevOps Pipeline create empty zip - azure

Question

I would like to ask you how to solve a problem which I encountered during a creation of Azure pipeline.
Problem description:
Probably, "brick" responsible for building a project not create a bin folder so I finally get empty zip.
Despite of the fact all test were successfully completed(passed).
My yaml file:
trigger:
- main
pool:
vmImage: 'windows-latest'
variables:
solution: '**/*.sln'
buildPlatform: 'Any CPU'
buildConfiguration: 'Release'
steps:
- task: NuGetToolInstaller#1
- task: UseDotNet#2
inputs:
packageType: 'sdk'
version: '3.1.x'
- task: NuGetCommand#2
inputs:
restoreSolution: '$(solution)'
- task: DotNetCoreCLI#2
inputs:
command: 'build'
projects: '**/XXX.EvaluateFunction.csproj'
- task: ArchiveFiles#2
inputs:
rootFolderOrFile: '$(Build.BinariesDirectory)'
includeRootFolder: true
archiveType: 'zip'
archiveFile: '$(Build.ArtifactStagingDirectory)/Evaluate.zip'
replaceExistingArchive: true
- task: PublishBuildArtifacts#1
inputs:
PathtoPublish: '$(Build.ArtifactStagingDirectory)'
ArtifactName: 'PortalArtifact'
publishLocation: 'Container'

According to the document about predefined variables: Build.BinariesDirectory is the local path on the agent you can use as an output folder for compiled binaries. Your yaml file does not use it as an output folder so that this folder is empty. You can use Build.BinariesDirectory as an output folder in .NET Core task: arguments: '--output $(Build.BinariesDirectory)'
Here is my complete sample:
trigger:
- main
pool:
vmImage: 'windows-latest'
variables:
solution: '**/*.csproj'
buildPlatform: 'Any CPU'
buildConfiguration: 'Release'
stages:
- stage: Build
jobs:
- job: Build
steps:
- task: DotNetCoreCLI#2
inputs:
command: 'restore'
projects: '**/*.csproj'
feedsToUse: 'select'
- task: DotNetCoreCLI#2
inputs:
command: 'build'
projects: '**/*.csproj'
arguments: '--configuration $(BuildConfiguration)'
- task: DotNetCoreCLI#2
inputs:
command: 'publish'
publishWebProjects: true
arguments: '--configuration $(BuildConfiguration) --output $(Build.BinariesDirectory)'
- task: ArchiveFiles#2
inputs:
rootFolderOrFile: '$(Build.BinariesDirectory)'
includeRootFolder: true
archiveType: 'zip'
archiveFile: '$(Build.ArtifactStagingDirectory)/Evaluate.zip'
replaceExistingArchive: true
- task: PublishBuildArtifacts#1
inputs:
PathtoPublish: '$(Build.ArtifactStagingDirectory)'
ArtifactName: 'drop'
publishLocation: 'Container'
