MEF .Net Core 1.0 NetStandard 1.6 initialize instance with parameters

Question

I am trying to get an instance of TestPrintTemplate.

I get an exception of 'No Export was found for the contract 'String "SomeData"' when I call container.GetExport(contractName).

How do I initialize the parameter in the TestPrintTemplate() constructor?

namespace TestPrintTemplate
{

    [Export("TestPrintTemplate",typeof(IPrintingTemplate))]
    public class TestPrintTemplate : IPrintingTemplate
    {

        [ImportingConstructor]
        public TestPrintTemplate([Import("SomeData")]  string data)
        {

        }
        public void Print()
        {
            return;
        }
    }

    public interface IPrintingTemplate
    {
        void Print();
    }


        public static T GetExportedValue<T>(this CompositionHost container, string contractName)
        {

            var result = new List<T>();
            string exportedTypeName = typeof(T).FullName;
            var item = container.GetExport<T>(contractName); // I get an exception here
            result.Add((T)item);
            return result.FirstOrDefault();
        }
