Deploy project with xUnit reference as NuGet package

Question

I have a library that contains some classes, which I need in several Unit Test projects. The library should be deployed as a NuGet package in my private repository. I already deployed some NuGet packages there, so I know what I have to do.

BUT: Inside of this library I need a reference to xUnit. And as soon as I add this reference, there is no more .nupkg file created when execute dotnet pack.

Another interesting effect is, that the project icon turns into a Unit Test icon as soon as I add xUnit:

Steps to reproduce:

1. Create a Class Library

2. Add a reference to the xUnit NuGet package

3. Right click the project and click on pack

Expected Behvior: there should be a .nupkg file in ./bin/Debug

Actual Behevior: there is no such file.

According to https://github.com/dotnet/cli/issues/7539, some projects seem to be "not packable" by default. You have to enable this manually by adding the following lines to your .csproj file:

<PropertyGroup>
  <IsPackable>true</IsPackable>
</PropertyGroup>

After that, the .nupkg file is created expected.
