asp.net – 将任何UI连接到我的应用程序

>数据模型(实体框架4.1)
>使用Enterprise Library 5.0验证应用程序块进行验证.
>由可重用类库管理的对象上下文.

因此,UI在代码上相当轻松,但我知道我还没完全在那里.

如果我想设置我的项目以便实现Web窗体,MVC,WPF桌面或Silverlight(甚至是Windows Phone 7)应用程序,我还需要采取哪些其他步骤？

这里有一些代码,故意简化,以说明我目前的游戏状态(我省略了代码约定和类库)：

(目前EF4 Model First和ASP .Net Web Forms)

自动生成实体的部分类

namespace MyNamespace.Database
{
    using Microsoft.Practices.EnterpriseLibrary.Validation;
    using Microsoft.Practices.EnterpriseLibrary.Validation.Validators;

    [HasSelfValidation]
    public partial class MyEntity : IMyEntity
    {
        [SelfValidation]
        public void Validate(ValidationResults validationResults)
        {
            // Custom validation can go here,just add a new ValidationResult 
            // to validationResults if the rule fails.

            if (validationResults != null)
            {
                validationResults.AddAllResults(
                    ValidationFactory
                        .CreateValidator<IMyEntity>()
                        .Validate(this));
            }
        }
    }
}

验证

namespace MyNamespace.Database
{
    using System.ComponentModel.DataAnnotations;
    using System.Diagnostics.Contracts;
    using Microsoft.Practices.EnterpriseLibrary.Validation;
    using Microsoft.Practices.EnterpriseLibrary.Validation.Validators;

    [ContractClass(typeof(MyEntityContract))]
    public interface IMyEntity
    {
        int Id
        {
            get;
            set;
        }

        [Required]
        [NotNullValidator]
        [StringLengthValidator(0,RangeBoundaryType.Ignore,50,RangeBoundaryType.Inclusive,MessageTemplate = "MyEntity Name must be 50 characters or less.")]
        string Name
        {
            get;
            set;
        }

        void Validate(ValidationResults validationResults);
    }
}

门面的数据访问

namespace MyNamespace.Facade
{
    using System.Collections.Generic;
    using System.Linq;
    using Common.ObjectContextManagement;
    using Database;

    public sealed class MyEntityFacade : FacadeBase<MyEntities,MyEntity>
    {
        public IEnumerable<MyEntity> GetAll()
        {
            return this.ObjectContext.MyEntitys
                .Distinct()
                .ToList();
        }
    }
}

Web App UI

using (new UnitOfWorkScope(false))
{
    this.MyEntityList.DataSource = new MyEntityFacade().GetAll();
    this.MyEntityList.DataBind();
}

// Or...

using (var scope = new UnitOfWorkScope(false))
{
    var myEntityFacade = new MyEntityFacade();

    var myEntity = new MyEntity();

    PopulateEntity(myEntity);

    // Validation errors are automatically presented 
    // to the user from the Validate method
    if (Validate(myEntity))
    {
        try
        {
            myEntityFacade.Add(myEntity);

            scope.SaveAllChanges();
        }
        catch (Exception exception)
        {
            Logging.Write("Error",LoggingLevel.Error,exception.Message);
        }
    }
}

我有多近？
