If you use Azure DevOps, don't edit project file. Use "dotnet restore"(https://docs.microsoft.com/en-us/azure/devops/pipelines/languages/dotnet-core?view=azure-devops) instead of Nuget restore:

I had this issue when building in Azure Devops and none of the other answers would fix it. My Build and Publish steps already had matching --runtime options.

  <PropertyGroup>
      ...
      <RuntimeIdentifier>win-x64</RuntimeIdentifier>

    checkLatest: true

Answer 5

What solved the issue for me, was to update the default NuGet package cache 'C:\Users\.nuget\packages' used for restore by changing the parameter in msvc:

Tools > Options > NuGet Package Manager > Package Restore > Allow NuGet to download missing package & Automatically check for missing packages during build in Visual Studio.
