Test project in project where project is in same folder as solution (codecrafters.io)

I am going through codecrafters.io DNS server with C#. The barebones project you get looks like this:

.
├── README.md
├── codecrafters-dns-server.csproj
├── codecrafters-dns-server.sln
├── codecrafters.yml
├── src
│   └── Server.cs
└── your_server.sh

.
├── README.md
├── codecrafters-dns-server.csproj
├── codecrafters-dns-server.sln
├── codecrafters.yml
├── src
│   └── Server.cs
└── your_server.sh

I want to add a unit test solution to this project, but I can't manage to get it working. From what I can tell, codecrafters really wants their project to keep this structure. I'm using Rider and tried adding new project to the solution, but then I get the following error:

CS0579: Duplicate 'global::System.Runtime.Versioning.TargetFrameworkAttribute' attribute

CS0579: Duplicate 'global::System.Runtime.Versioning.TargetFrameworkAttribute' attribute

I attempted to fix this by adding the following to the .csproj file.

    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <GenerateTargetFrameworkAttribute>false</GenerateTargetFrameworkAttribute>

    <GenerateAssemblyInfo>false</GenerateAssemblyInfo>
    <GenerateTargetFrameworkAttribute>false</GenerateTargetFrameworkAttribute>

Is there a way to create a unit test project that does not mess with the codecrafters repository?

You cannot reference a project from another solution, so I take it that I have to add the test project to the same solution. So back to square 1 I guess? 🙂 Oh, I added a Test file and then just run it from the same project, that works too!
