Appveyor: Package content hash validation failed, The package is different than the last restore

Question

I would like to configure CI in Appveyor for a .net project and I am struggling with following errors:

error NU1403: Package content hash validation failed for System.Collections.NonGeneric.4.3.0. The package is different than the last restore.

Every project restore happens to throw similar thing

There was similar question and one advice was to clear nuget cache.

Whats the best course of action here?

Thanks

Answer 1

At Feodor suggestion I added powershell script which removes package.lock.json files and it worked.

before_build:
  - choco install opencover.portable
  - choco install codecov
    - ps: >-
        Get-ChildItem .\ -include packages.lock.json -Recurse | foreach ($_) { remove-item $_.fullname -Force }
  - cmd: dotnet --version
  - cmd: dotnet restore
