我正在使用 Devexpress。通过点击此链接（http://www.devexpress.com/Support/Center/Example/Details/E3863），我在下面编写了此代码。它产生了我在下面定义的两个错误。当我输入程序集引用时，它会生成一个错误，即

Warning 7 Unknown build error, 'Cannot resolve dependency to assembly 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event.'  LINQServer

错误列表：

       Error    1   The tag 'Interaction.Behaviors' does not exist in XML namespace 'http://schemas.microsoft.com/expression/2010/interactivity'. Line 39 Position 14.  C:\Documents\Visual Studio 2010\Projects\LINQServer\LINQServer\MainWindow.xaml  39  14  LINQServer


        Error   2   The type or namespace name 'Interactivity' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?)    C:Documents\Visual Studio 2010\Projects\LINQServer\LINQServer\EntityServerModeCRUDBehavior.cs   4   22  LINQServer

Error   6   The attachable property 'DataSource' was not found in type 'EntityServerModeCRUDBehavior'.  C:\Users\must\Documents\Visual Studio 2010\Projects\LINQServer\LINQServer\MainWindow.xaml   46  22  LINQServer

错误 5 找不到类型“crud:EntityServerModeCRUDBehavior”。确认您没有丢失程序集引用并且所有引用的程序集都已构建。C:\Users\must\Documents\Visual Studio 2010\Projects\LINQServer\LINQServer\MainWindow.xaml 40 18 LINQServer

我该如何解决这些错误？你能回答我的问题吗？

在解决方案资源管理器中右键单击您的项目文件。选择 Add Reference，转到 Assemblies 选项卡并找到 System.Windows。添加参考，瞧。
