我正在尝试启动并运行 EPiServer 项目，但出现此错误：
System.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. The following information may be a subset of the Type/LoaderException information present - inspect with debugger for complete view.

我用dotPeek查看了dll，所有类型都在那里。它methods找不到的不存在，但我找不到任何版本EPiServer.Legacy4.dll。
有人知道怎么修这个东西吗？
