MSFT 声称 .NET 4.5 向后兼容 .NET 4。我继续安装了 .NET 4.5 和 VS 11，然后创建了一个新的 ASP.NET MVC 4 Web API 项目。当我将 Castle.ActiveRecord.dll（版本 3.0.0.0）引用到我的 Web API 项目中时，每个控制器操作都会生成此错误：
[FileNotFoundException: Could not load file or assembly 'Lucene.Net, Version=2.3.1.3, Culture=neutral, PublicKeyToken=45b1dda587cdc860' or one of its dependencies. The system cannot find the file specified.]

这很有趣，因为从我读到的。版本 2.3.1.3 是 Lucene (java) 版本，而不是 Lucene.Net 版本。为了确定，我检查了 NuGet，它没有可用于 Lucene.Net 的版本 2.3.1.3。
是什么赋予了？我很想运行新的 ASP.NET MVC 4 Web API 项目，因为它融合了我对 ASP.NET MVC 和 WCF Web API 的喜爱。关于如何解决这个问题的任何想法？
