Warning xUnit1041 on constructor parameter after upgrading to 2.6.0

[janhruban]

After upgrading xUnit versions from 2.4.1 to 2.9.2 and Xunit.Extensions.AssemblyFixture from 2.4.1 to 2.6.0, we are encountering the warning xUnit1041 for the assembly fixture parameter in the constructor (dbSetup):

public class DbUtilsTests : IAssemblyFixture<DbSetup>
{
    private readonly IServiceCollection _services;

    public DbUtilsTests(DbSetup dbSetup, ITestOutputHelper testOutputHelper)
    {
    }
}

Do you have any suggestions on how to resolve this warning?
