Is there a mapper to/from EDM/OData types to CLR types?

Here's some code that converts an XML element (from an OData feed) and converts it to an ExpandoObject.

private static object GetTypedEdmValue(string type, string value, bool isnull){    if (isnull) return null;    if (string.IsNullOrEmpty(type)) return value;    switch (type)    {        case "Edm.String": return value;        case "Edm.Byte": return Convert.ChangeType(value, typeof(byte));        case "Edm.SByte": return Convert.ChangeType(value, typeof(sbyte));        case "Edm.Int16": return Convert.ChangeType(value, typeof(short));        case "Edm.Int32": return Convert.ChangeType(value, typeof(int));        case "Edm.Int64": return Convert.ChangeType(value, typeof(long));        case "Edm.Double": return Convert.ChangeType(value, typeof(double));        case "Edm.Single": return Convert.ChangeType(value, typeof(float));        case "Edm.Boolean": return Convert.ChangeType(value, typeof(bool));        case "Edm.Decimal": return Convert.ChangeType(value, typeof(decimal));        case "Edm.DateTime": return XmlConvert.ToDateTime(value, XmlDateTimeSerializationMode.RoundtripKind);        case "Edm.Binary": return Convert.FromBase64String(value);        case "Edm.Guid": return new Guid(value);        default: throw new NotSupportedException("Not supported type " + type);    }}private static ExpandoObject EntryToExpandoObject(XElement entry){    XNamespace xmlnsm = "http://schemas.microsoft.com/ado/2007/08/dataservices/metadata",                xmlns = "http://www.w3.org/2005/Atom";    ExpandoObject entity = new ExpandoObject();    var dic = (IDictionary<string, object>)entity;    foreach (var property in entry.Element(xmlns + "content").Element(xmlnsm + "properties").Elements())    {        var name = property.Name.LocalName;        var type = property.Attribute(xmlnsm + "type") != null ? property.Attribute(xmlnsm + "type").Value : "Edm.String";        var isNull = property.Attribute(xmlnsm + "null") != null && string.Equals("true", property.Attribute(xmlnsm + "null").Value, StringComparison.OrdinalIgnoreCase);        var value = property.Value;        dic[name] = GetTypedEdmValue(type, value, isNull);    }    return entity;}
