VS2010 beta,sl4 beta 升级到 RC 后，原工程如果使用RIA需要做的更改

127000 楼主

最近在升级原先使用Beta制作的项目，在升级中参考微软的说明，顺利完成了多个项目的升级，在此将升级的部分过程说明一下，帮助大家少走弯路。

在项目中以下内容会做变化
1.System.Windows.Ria --> System.ServiceModel.DomainServices.Client + System.ServiceModel.DomainServices.Client.Web
2.System.Windows.Controls.Ria --> System.Windows.Controls.DomainServices
3.System.Web.Ria --> System.ServiceModel.DomainServices.Server + System.ServiceModel.DomainServices.Hosting
4.System.Web.DomainServices --> System.ServiceModel.DomainServices.Server
5.System.Web.DomainServices.EntityFramework   --> System.ServicesModel.DomainServices.EntityFramework
6.System.Web.DomainServices.LinqToSql --> Microsoft.ServiceModel.DomainServices.LinqToSql
7.System.Web.DomainServices.Proxies --> Microsoft.ServiceModel.DomainServices.Hosting.Local
8.System.Windows.Controls.Ria.Design --> System.Windows.Controls.DomainServices.Design
9.System.Windows.Controls.Ria.Expression.Design --> System.Windows.Controls.DomainServices.Expression.Design
10.System.Windows.Controls.Ria.VisualStudio.Design --> System.Windows.Controls.DomainServices.VisualStudio.Design

在引用中以下内容会有变化
1.System.Web.DomainServices --> System.ServiceModel.DomainServices.Server
2.System.Web.DomainServices.Providers --> System.ServiceModel.DomainServices.EntityFramework (for LinqToEntities classes)
   Microsoft.ServiceModel.DomainServices.LinqToSql (for LinqToSql classes)
3.System.Web.Ria --> System.ServiceModel.DomainServices.Hosting
4.System.Web.Ria.ApplicationServices --> System.ServiceModel.DomainServices.Server.ApplicationServices
5.System.Web.Ria.Data --> Namespace removed.
   System.ServiceModel.DomainServices.
   Composition Attribute moved to System.ComponentModel.DataAnnotations.
   OperationError renamed to ValidationResultInfo and now available in both         System.ServiceModel.DomainServices.Client and         System.ServiceModel.DomainServices.Server.
6.System.Web.Ria.Services --> System.ServiceModel.DomainServices.Hosting
7.System.Windows.Controls.Ria --> System.Windows.Controls
8.System.Windows.Data --> System.Windows.Controls
9.System.Windows.Ria --> System.ServiceModel.DomainServices.Client
10.System.Windows.Ria.ApplicationServices --> System.ServiceModel.DomainServices.Client.ApplicationServices
11.System.Windows.Ria.Services --> System.ServiceModel.DomainServices.Client

以上引用位置如下
%Program Files%\Microsoft SDKs\RIA Services\v1.0\Libraries\Server
%Program Files%\Microsoft SDKs\RIA Services\v1.0\Libraries\Silverlight
%Program Files%\Microsoft SDKs\RIA Services\v1.0\Toolkit\Libraries\Server

如果更改完成，再编译，目前会提示.gs.cs 中[WebGet]有错误，需要再添加System.ServiceModel.Web.Extensions引用，这样就基本完成修改，接下来就是要修改 DomainService.cs 文件，需要修改添加，更新，删除的内容，修改方法如下(将绿色内容删除，红色内容改变为蓝色)：
1.添加部分
public void InsertProduct(Product product)
{
  if (product.EntityState != EntityState.Added)
  {
    if (product.EntityState != EntityState.Detached)
    {
      ObjectContext.ObjectStateManager.ChangeObjectState(product, EntityState.Added);
    }
    else
    {
       ObjectContext.AddObject("Products", product);  --> ObjectContext.Products.AddObject(product);    }
  }
}

2.更新部分
public void UpdateProduct(Product current)
{
  ObjectContext.AttachAsModified(current, this.ChangeSet.GetOriginal(current)); --> ObjectContext.Products.AttachAsModified(current, this.ChangeSet.GetOriginal(current));
}

3.删除部分
public void DeleteProduct(Product product)
{
  if (product.EntityState == EntityState.Detached)
  {
    ObjectContext.Attach(product); --> ObjectContext.Products.Attach(product);
  }
  ObjectContext.DeleteObject(product); --> ObjectContext.Products.DeleteObject(product);
}


如果项目中还使用了 Richtextarea 控件，还需要更改 xaml 文件，修改为 Richtextbox.

基本上大的内容就这么多，其实在有些项目中还有其他的问题，但根据微软的文档逐步调试，都得到了解决。
