C# WebApi正在尝试加载Owin，而它'；这不在参考资料中

我正在制作一个双层WebApi，我犯了一个错误，我认为我把两个项目联系在一起了

现在，我的applicationServices（内部WebApi）尝试加载Owin，即使它不在引用中，也不在packages.config中。 我不知道指定在哪里加载Owin。我收到的错误消息是：

         <H1>Erreur du serveur dans l'application '/ApplicationServices'.
            <hr width=100% size=1 color=silver>
        </H1>
        <h2>
            <i>Impossible de charger le fichier ou l'assembly 'Owin, Version=1.0.0.0, Culture=neutral, PublicKeyToken=f0ebd12fd5e55cc5' ou une de ses d&#233;pendances. Le fichier sp&#233;cifi&#233; est introuvable.</i>
        </h2>

Erreur du serveur dans l'application'/ApplicationServices'。

不可能对“组装”Owin中的le fichier进行充电，版本=1.0.0.0，文化=中性，PublicKeyToken=f0ebd12fd5e55cc5“您需要一个和#233；吊坠。Le fichier spé；cifi&233；最内向的。

（对于不懂法语的人：无法加载文件或程序集Owin或其依赖项之一，无法找到文件）

我认为这是因为我不小心将我的两个项目（使用Owin的项目和这个项目）连接起来，使它们调用同一个类库

我不知道该怎么办，你能帮我吗？

删除obj和bin文件夹，一些旧的owin dll可能会从以前的版本中保留下来。

你尝试过删除bin和obj文件夹吗！！非常感谢您，您应该发布答案，以便我能够标记您的答案，并通过解释解决了我的问题？：D感谢您的提醒：）
