As a workaround, you can put the following in your .NET Core project which references .NET Standard 2.1:

  <Target Name="WorkaroundNetStandard" AfterTargets="ResolvePackageAssets">
    <ItemGroup>
      <TransitiveFrameworkReference Remove="NETStandard.Library" />
    </ItemGroup>
  </Target>

This is working using the latest VS build and the latest preview6 CLI.

@livarcocc - Specifically which versions? I still get this error with the following versions:

NetCoreApp3.0: preview6-27804-01 Visual Studio: 16.1.3

You have to use the latest Visual Studio preview.

@robborden Can you open a new issue for the failures you’re encountering? The error message is the same but I don’t believe the root cause is the same as this issue which has been fixed. Thanks!

@dsplaisted you say it should be fix now? I still can’t build my solution using Visual Studio Build task in TFS. The VS version installed on the build machine is : 16.3.29324.140 I have the following error : ##[error]C:\Program Files\dotnet\sdk\3.0.100\Sdks\Microsoft.NET.Sdk\targets\Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(263,5): Error NETSDK1073: The FrameworkReference ‘NETStandard.Library’ was not recognized

The CSproj of this project contains : “PropertyGroup <TargetFramework>netstandard2.1</TargetFramework> /PropertyGroup”

The main project.csproj contains : “PropertyGroup <TargetFramework>netcoreapp3.0</TargetFramework> <OutputPath>…..\bin$(Configuration)</OutputPath> /PropertyGroup”

I’m still seeing this issue when building with Azure DevOps using the MSBuild Task, even on the 3.0.100 release of .net core sdk.

Adding this also solves this error in projects that fail to build:

<GenerateErrorForMissingTargetingPacks>false</GenerateErrorForMissingTargetingPacks>
