Unable to publish project on Linux on 2.1 Preview 2

Hi, my project built and published no problem on 2.0 and 2.1 Preview 1

but now I get:

/home/dan/repos/AvalonStudio/AvalonStudio/AvalonStudio.Languages.Xaml/AvalonStudio.Languages.Xaml.csproj : error NU1605: Detected package downgrade: Microsoft.NETCore.App from 2.0.6 to 2.0.0. Reference the package directly from the project to select a different version.  [/home/dan/repos/AvalonStudio/AvalonStudio/AvalonStudio/AvalonStudio.csproj]
/home/dan/repos/AvalonStudio/AvalonStudio/AvalonStudio.Languages.Xaml/AvalonStudio.Languages.Xaml.csproj : error NU1605:  AvalonStudio.Languages.Xaml -> Avalonia.Designer.HostApp -> Microsoft.NETCore.App (>= 2.0.6)  [/home/dan/repos/AvalonStudio/AvalonStudio/AvalonStudio/AvalonStudio.csproj]
/home/dan/repos/AvalonStudio/AvalonStudio/AvalonStudio.Languages.Xaml/AvalonStudio.Languages.Xaml.csproj : error NU1605:  AvalonStudio.Languages.Xaml -> Microsoft.NETCore.App (>= 2.0.0) [/home/dan/repos/AvalonStudio/AvalonStudio/AvalonStudio/AvalonStudio.csproj]

AvalonStudio.csproj is a netcoreapp2.0 project. AvalonStudio.Languages.Xaml.csprojis a netcoreapp2.0 project Avalonia.Designer.HostApp is also a netcoreapp2.0 project.

The previous version was happy with this.

The repository containing the code at specific commit to repro is here: https://github.com/VitalElement/AvalonStudio/commit/e947164d84a72f61a5b44dfcb4b5c93e7af2d63e

git clone --recursive cd AvalonStudio\AvalonStudio\AvalonStudio dotnet publish -c Release -f netcoreapp2.0 -r debian.8-x64

Let me know if I can provide any further information.

Thanks in advance.

@danwalmsley you will need to add

  <PropertyGroup>
    <TargetLatestRuntimePatch>true</TargetLatestRuntimePatch>
  </PropertyGroup>

to the host app project as well for this error.

Or publish using

dotnet publish -f netcoreapp2.0 -r win7-x64 -p:TargetLatestRuntimePatch=true

Thanks finally I managed to get the workaround to work 😃
