Hi Bob,

A possible workaround is to explicitly load a dictionary for the "en-US" culture: 

namespace RteSpellcheckNetCore
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            Stream tdfFileStream = typeof(Form1).Assembly.GetManifestResourceStream("RteSpellcheckNetCore.en-US.tdf");
            RadDictionary dictionary = new RadDictionary();
            dictionary.Load(tdfFileStream);
            ((DocumentSpellChecker)this.radRichTextEditor1.SpellChecker).AddDictionary(dictionary, new CultureInfo("en-US"));
        }

    }
}

Here you can download dictionaries for different cultures: https://www.telerik.com/support/code-library/dictionaries-for-radspellchecker. Then you will need to embed the downloaded file as a resource in your project.
