VS2010 Silverlight 模板未编译：“WebContextBase 未定义”。发生了什么事？我怎样才能让它发挥作用？

我正开始首次探索 Silverlight RIA 和 EF4，但我无法让项目直接运行 VS2010 SP1 附带的模板。

请记住，我所做的是安装全新的 Windows 7 VM，然后立即安装 LightSwitch Beta 2。随后，我添加了 VS2010 Premium，并应用了 Service Pack 1。

模板应用程序的客户端部分启动了三个警告和两个错误；详细信息发布在下面。它在生成到 Web.g.vb（和 Web.g.cs）文件的代码中寻找找不到的 WebContextBase 类。到目前为止，这个项目完全是根据解决方案模板生成的；我没有在 VS2010 生成的内容中添加一行代码。

此后，我已经让 EF4 在 WinForms 项目和 Light Switch 项目中正常工作。

这是怎么回事？我该如何解决？

I'm beginning my first explorations into Silverlight RIAs and EF4, but I can't get a project to run right off the templates that ship with VS2010 SP1.

Bear in mind here that what I've done is to install a brand new Windows 7 VM, and then I immediately installed LightSwitch Beta 2. Following that, I added VS2010 Premium, and applied Service Pack 1 to that.

The client portion of the Template app is kicking off three warnings and two errors; the details are posted below. It's looking for a WebContextBase class that it can't find, in code that it generated into Web.g.vb (and Web.g.cs) files. So far this project is entirely generated off the solution template; I haven't added a single line of code to what VS2010 generated.

I've since gotten EF4 to work fine in WinForms projects and Light Switch projects.

What's going on here, and how do I fix it?
