Question

我有一个我在IIS 7中托管的Web API服务。当我调用该服务时，我收到此错误：

System.IO.FileNotFoundException无法加载文件或程序集“Microsoft.ReportViewer.WebForms，Version = 8.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a”或其依赖项之一。系统找不到指定的文件。

我在整个解决方案和项目中都看了很多，但我没有对ReportViewer的任何引用。有没有人知道为什么我会收到这个错误？从错误中看，它正在执行库的运行时加载。 ReportViewer是否需要System.Web.Http？

无法加载文件或程序集'Microsoft.ReportViewer.WebForms，但我不使用该库
