Cannot convert type IEnumerable to List

Programming in C#: Cannot convert type IEnumerable to List on newest questions tagged c# – Stack Overflow

I have been using C# with Unity3d for a few years now, but am just starting with .NET programming. I get the error:

Cannot implicitly convert type ‘System.Collections.Generic.IEnumerable<URL>‘ to ‘System.Collections.Generic.List<URL>‘. An explicit conversion exists (are you missing a cast?)

Here is my code:

namespace TestBrowserHistory
{
    public class Test1
    {
        public Test1()
        {

        }
          static void Main()
    {
        InternetExplorer myClass = new InternetExplorer();
        List<URL> calledList = myClass.GetHistory();
        Console.WriteLine("Hello!");
        Console.WriteLine(calledList[1]);
        Console.ReadLine();
    }
    }
}

public class InternetExplorer
{
    // List of URL objects
    public List<URL> URLs { get; set; }
    public IEnumerable<URL> GetHistory()
    {
        // Initiate main object
        UrlHistoryWrapperClass urlhistory = new UrlHistoryWrapperClass();

        // Enumerate URLs in History
        UrlHistoryWrapperClass.STATURLEnumerator enumerator =
                                           urlhistory.GetEnumerator();

        // Iterate through the enumeration
        while (enumerator.MoveNext())
        {
            // Obtain URL and Title
            string url = enumerator.Current.URL.Replace('\'', ' ');
            // In the title, eliminate single quotes to avoid confusion
            string title = string.IsNullOrEmpty(enumerator.Current.Title)
                      ? enumerator.Current.Title.Replace('\'', ' ') : "";

            // Create new entry
            URL U = new URL(url, title, "Internet Explorer");

            // Add entry to list
            URLs.Add(U);
        }

        // Optional
        enumerator.Reset();

        // Clear URL History
        urlhistory.ClearHistory();

        return URLs;
    }

}

Thanks for any help!
