As of EntitySpaces 2007 v0.0507, we have exposed the IMetadata interfaces on the nested "es" variable. This example is using the Employees class generated from the Microsoft SQL Northwind database.

Employees emp = new Employees();
esProviderSpecificMetadata spec = emp.es.Meta.GetProviderMetadata("esDefault");
foreach (esColumnMetadata col in emp.es.Meta.Columns)
{
    Console.WriteLine("PropertyName: " + col.PropertyName);
    Console.WriteLine("ColumnName  : " + col.Name);
    Console.WriteLine("CharLength  : " + col.CharacterMaxLength.ToString());

    esTypeMap map = spec.GetTypeMap(col.Name);

    Console.WriteLine("Native Type : " + map.NativeType);
    Console.WriteLine("System Type : " + map.SystemType);
    Console.WriteLine("---------------------------------");
}

Here is the output:

PropertyName: EmployeeID
ColumnName  : EmployeeID
CharLength  : 0
Native Type : int
System Type : System.Int32
---------------------------------
PropertyName: LastName
ColumnName  : LastName
CharLength  : 20
