Required references did not load

I get a lot of errors like these:

Required references did not load for [project name] or referenced project. Run `dotnet restore` prior to formatting.

Running dotnet restore doesn’t help, though. This happens for a lot of the projects in my solution, not all of them, though.

I’m running v5.0.152601 on Linux (NixOS).

Unfortunately none of the projects are open source. I’m gonna investigate a little further tomorrow and maybe I can create a sample project to reproduce the issue.

I am facing this issue after upgrading from .netcoreapp3.1 to net6.0 TFM (SDK 6.0.401)

(dotnet format also changed its API… so the previous CLI command does not work so one has to adapt to the breaking change)

I ran dotnet restore multiple times even with -f flag.

...
Required references did not load for MyProjectREDACTED(net6.0) or referenced project. Run `dotnet restore` prior to formatting.

Any ideas anyone… I get the same issue when I target my referenced libraries to TFM net6.0

My repo root global.json targets 3.1.416, but the one on the project targets 6.0.401, I run dotnet format from repo root. I am trying to gradually upgrade projects but this is hard to pass…

In the target csproj I added the nugets the internet advises… but no help:

    <PackageReference Include="Microsoft.CodeAnalysis" Version="4.3.1" />
    <PackageReference Include="Microsoft.CodeAnalysis.Compilers" Version="4.3.1" />
    <PackageReference Include="Microsoft.Net.Compilers.Toolset" Version="4.3.1">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
