C# error when passing an instance of a derived class to a method

Question

I got this error

CS1503 C# Argument 1: cannot convert from 'SerieSettings<SeriesLine>' to 'SerieSettings<ISeries>'

when I pass a SeriesLine type object as parameter, in this way

GraphLibrary().MultiTypeChart(settings => 
{
    settings.AddSeries((SerieSettings<SeriesLine>)(s =>
    {
        s.Name = "Temperatures";
    }));
});

to this method

public class GraphLibrary(){
    public GenericChartExtension MultiTypeChart(Action<GenericChartSettings> settings)
    {
        return new GenericChartExtension(settings);
    }
}

where GenericChartExtension and BaseChartSettings are

public sealed class GenericChartSettings : BaseChartSettings<ISeries>
{
}

public sealed class GenericChartExtension : BaseChartExtension<GenericChartSettings>
{
    public GenericChartExtension(Action<GenericChartSettings> applySettings) : base(applySettings) { }

    public override HtmlString Render()
    {
        return ChartSettings.Settings.Render();
    }
}

derived of BaseChartSettings and BaseChartExtension

public class BaseChartExtension<T>
{
    protected readonly T ChartSettings;

    public BaseChartExtension(Action<T> applySettings)
    {
        ChartSettings = (T) Activator.CreateInstance(typeof (T));
        applySettings(ChartSettings);
    }
//....
public class BaseChartSettings<T> where T : ISeries
{
    public void AddSeries(SerieSettings<T> s) { Settings.AddSeries(s); }

SerieSettings is a delegate

public delegate void SerieSettings<V>(V s);

and SeriesLine is a derived of ISeries

public class SeriesLine: ISeries
