Cannot add Serilog.Sinks.File to .NET Core 3.x

[kofifus]

Using latest .NET Core v3.0.0-preview5

My proj has:

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Hosting.WindowsServices" Version="3.0.0-preview5-19227-01" />
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="3.0.0-preview5-19227-01" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="3.0.0-preview5.19227.1" />
    <PackageReference Include="Newtonsoft.Json" Version="12.0.2" />
    <PackageReference Include="Serilog" Version="2.9.0-dev-01091" />
    <PackageReference Include="Serilog.Extensions.Hosting" Version="2.0.1-dev-00009" />
  </ItemGroup>

I then try to install package Serilog.Sinks.File

I get:

How do I solve this ?

Hi! You can add:

    <PackageReference Include="System.IO.FileSystem.Primitives" Version="4.3.0" />

to your CSPROJ.

I think we may need to update the dependency versions in this package to avoid this annoyance once 3.0 is out.

I just ran into this in a netcoreapp3.1 project. I had to add the following:

    <PackageReference Include="System.IO.FileSystem.Primitives">
      <Version>4.3.0</Version>
    </PackageReference>
    <PackageReference Include="System.Text.Encoding.Extensions">
      <Version>4.3.0</Version>
    </PackageReference>

Can anything be done to not require these? Serilog.Sinks.File is the only package in this fairly large project for which I've had to do this.

Thanks for the nudge, @alexrp - reopening so that someone might be able to PR an update for this 👍

The PackageReference workaround didn't work for me for some reason. In my case, I'm trying to bundle a .NET Core 3.1 WPF application into a Desktop Bridge project.

For now I've had to simply remove the reference to Serilog.Sinks.File, which of course is not ideal. I see there is a fix pending, so I'm hoping that I'll be able to re-add it soon.

Any chance the production version of this will be fixed anytime soon? I can build for windows platforms on .net core 3.1 but when I build for linux-x64 I get the downgrade messages as posted above.

I also tried using the prerelease nuget package, but it didn't fix it either.
