ASP.NET Dynamic Data - Generate the Metadata Classes from Entity Framework Quickly

Problem:
It's time-consuming to write the metadata classes for your entity framework assuming you have many classes.

Solution:
Run my following class using
EFMetadataGenerator.Generate( "MIPortalModel" ,@"c:\MIPortalEntities.cs");

Then all the metadata classes including their properties will be generated for you.

using System;
using System.Linq;
using System.Reflection;
using System.Text;

/// <summary>
/// Summary description for EFMetadataGenerator
/// </summary>
public class EFMetadataGenerator
{
     /// <summary>
     /// </summary>
     /// <param name="fromNamespace">This is the namespace of your EntityFramework</param>
     /// <param nam/// </summary>e="toFile">This is the path of the file on which you want the results to be saved</param>

        {

            foreach (var type in types) {
                result.Append(GenerateMetadataClasses(type));
            }
        }
        result.Append(AddFooter());
        System.IO.File.WriteAllText(toFile, result.ToString());
    }
