几个月前，我下载了 DevExpress 控件的 v12.2 进行免费试用。我只是简单地建立了一个项目，但那时从未真正使用过它们。

试用期延长后，我现在正在使用它们。

由于我使用的是 Visual Web Developer 2010 Express，我没有看到 DevExpress 控件模板，因此我使用此处给出的说明手动将 DevExpress 注册到我的 ASP.NET MVC 项目中：

http://documentation.devexpress.com/#AspNet/CustomDocument8163

我遵循了这封信的所有指示。我什至将所有版本引用从 v13.1 更改为 v12.2，从 13.1.6.0 更改为 12.2.10.0。

但是当我第一次运行该项目时，我得到了黄屏死机和运行时异常，如下图所示。

然后我记得要添加到system.web -> pages -> namespaces元素的 DevExpress 命名空间必须在根 web.config 中Views/web.config而不是在根 web.config 中完成。他们的文档中没有提到这一点，但我从上次使用他们的控件时的反复试验中记住了这一点。

然后，第一个异常消失了，现在我得到了这个异常。

在此处输入图像描述

我什至通过安装工具文件夹中的转换器工具运行该项目，但没有运气。我得到相同的运行时异常。我什至写信给他们的支持，但他们似乎根本没有回应。

如果您想自己尝试一下，这里是示例项目。它只是一个空白的 ASP.NET MVC 项目，其中 web.config 中的更改和Home/Index视图中的一些样板代码是从您的在线文档中给出的示例中复制而来的。
