MSB3245: Could not resolve this reference. Could not locate the assembly

I am getting the following error message, when i build the code using the Azure DevOps. The same code, when I build locally, I am able to build it successfully.

Warning MSB3245: Could not resolve this reference. Could not locate the assembly "Azure.Core, Version=1.20.0.0, Culture=neutral, PublicKeyToken=92742159e12e44c8, processorArchitecture=MSIL". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.

I am not able to figure out what am i missing here.

Following is the YAML FIle:

# Starter pipeline
# Start with a minimal pipeline that you can customize to build and deploy your code.
# Add steps that build, run tests, deploy, and more:
# https://aka.ms/yaml

trigger:
- feature/bla

variables:
  buildPlatform: 'Any CPU'
  buildConfiguration: 'Release'

pool:
  vmImage: 'windows-latest'

steps:

- task: NuGetToolInstaller@1


- task: NuGetCommand@2
  inputs:
    command: 'restore'
    restoreSolution: './src/Lidia.SSIS.ScriptUtils.sln'    
    
    
- task: VSBuild@1
  inputs:
    solution: './src/bla.sln'
    vsVersion: '16.0'
    msbuildArgs: '/p:OutDir=$(build.artifactstagingdirectory)/bla'

In our case we had to define restoreDirectory parameter to the relative directory from the solution, so in our case: ../packages.

If no folder is specified, packages are restored into a packages/ folder alongside the selected solution, packages.config, or project.json (in this case to src/SomeDirectory/packages).

steps:
- task: NuGetCommand@2
  displayName: 'NuGet restore Tests'
  inputs:
    restoreSolution: src/SomeDirectory/SomeSolution.sln
    includeNuGetOrg: false
    restoreDirectory: ../packages

MSB3245: Could not resolve this reference. Could not locate the assembly

That's because you specify the restoreDirectory for the nuget restore task.

If you are not specifying the packages folder locally when you build the solution, you should not specify it in Azure-devops.

When you specify the restoreDirectory for the nuget restore task, the restored packages are saved in the c:\packages folder, however, the referenced path for the packages in the project are still for the old path.

That is the reason why you get the error "Could not locate the assembly".

You should not use paths that reference drives in azure pipelines tasks, as you don't have access to directories outside the scope of the pipeline agent, so in this case your nuget restore task does not work. Use predefined variables (https://learn.microsoft.com/en-us/azure/devops/pipelines/build/variables?view=azure-devops&tabs=yaml) when referencing, like:

- task: VSBuild@1
  inputs:
    solution: '$(Build.SourcesDirectory)/src/bla.sln'

Not sure why the restore task has a restoredirectory specified. If you need to use a specific directory, again, use predefined build or agent variables. Generally speaking though, the packages should be restored and referenced without needing to specify a restoredirectory: https://learn.microsoft.com/en-us/azure/devops/pipelines/tasks/package/nuget?view=azure-devops#examples
