Creating column at runtime, with DataTemplateSelector. Have exception at XamlReader.Load: System.Windows.StaticResourceExtension. How can i load resources?

var column = new DataGridTemplateColumn();
            column.Header = (i.Hour + 1).ToString();
            column.Width = 30;
var parserContext = new ParserContext();
parserContext.XmlnsDictionary.Add("", "http://schemas.microsoft.com/winfx/2006/xaml/presentation");
parserContext.XmlnsDictionary.Add("x", "http://schemas.microsoft.com/winfx/2006/xaml");
parserContext.XmlnsDictionary.Add("local", "clr-namespace:ССПИ;assembly=ССПИ");
column.CellTemplateSelector = (DataTemplateSelector)XamlReader.Load(
                new MemoryStream(Encoding.Default.GetBytes(
                    @"<local:ExtendedTemplateSelector TextBlockTemplate='{StaticResource TextBlockTemplate}' CheckBoxTemplate='{StaticResource CheckBoxTemplate}'/>"
                )),parserContext);        
dataGrid1.Columns.Add(column);

    in your App.xaml:

    <App.Resources>
