Required references did not load

[felschr]

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).

@felschr Sorry you are running into this. I haven't encountered this issue myself. Can you share a project with us that repros this behavior?

[felschr]

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.

Upgrading the dotnet SDK from 3.1.102 to 3.1.402 ultimately resolved the issue for me.

If it's of any interest I was able to reproduce the issue with SDK 3.1.102 using @canton7's test repo which they shared in #584 (that issue also seems to be resolved by updating the SDK).

Closing this issue as we've seen no reply to the request for more information. If you are able to get the requested information, please add it to the issue and we will retriage it.

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.

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>
