无法加载文件或程序集“System.Web.DataVisualization”或一个依赖

Question

之一我接收此错误：

Server Error in Application. 

Could not load file or assembly 'System.Web.DataVisualization' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. 
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.BadImageFormatException: Could not load file or assembly 'System.Web.DataVisualization' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. 

Assembly Load Trace: The following information can be helpful to determine why the assembly 'System.Web.DataVisualization' could not be loaded. 

我接收此错误后，我改变的system.web.DataVisualization.dll属性是Copy Local= true，并且这dll也在bin目录中。但错误保持不变。

我该怎么做才能摆脱这个错误。
