CS8032 analyzer warnings in empty EF Core project in Rider
I'm evaluating JetBrains Rider 2023.3 on Linux and almost immediately ran into a compiler warning that I don't understand. Attempting to isolate it, I created a new solution containing a .NET 6 class library project. The project has only one explicit dependency, Microsoft.EntityFrameworkCore 7.0.14. The project contains no class files. Build emits these CS8032 warnings:
An instance of analyzer Microsoft.EntityFrameworkCore.InternalUsageDiagnosticAnalyzer cannot be created from /home/kevin/.nuget/packages/microsoft.entityframeworkcore.analyzers/7.0.14/analyzers/dotnet/cs/Microsoft.EntityFrameworkCore.Analyzers.dll : Could not load file or assembly 'Microsoft.CodeAnalysis, Version=4.2.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. The system cannot find the file specified..

The system cannot find the file specified..
The same warnings sometimes appear with dotnet build the command line and sometimes do not. I can consistently make them appear on the command line by running dotnet build --force after a build in Rider, but only once:
- Trigger a build in Rider by editing a comment. Warnings appear.
- Run dotnet build on the command line. Warnings do not appear.
- Run dotnet build --force on the command line. Warnings appear.
- Run dotnet build --force again. Warnings do not appear.
Is this caused by something Rider is trying to do, or perhaps some misconfiguration?

I resolved this by installing Microsoft's dotnet-sdk-8.0 instead of Ubuntu's dotnet-sdk-6.0. Here's a loose summary of Microsoft's instructions.
- Remove existing dotnet packages:
sudo apt remove 'dotnet*' 'aspnet*' 'netstandard*'
- Deprioritize the Ubuntu packages by creating a file in
/etc/apt/preferences.d/containing the following:
Package: dotnet* aspnet* netstandard*
Pin: origin "archive.ubuntu.com"
Pin-Priority: -10
- Add the Microsoft repo:
sudo apt-add-repository https://packages.microsoft.com/ubuntu/22.04/prod
- Install the .NET 8 SDK:
sudo apt update
sudo apt install dotnet-sdk-8.0
