我试图添加一个普通(即不是vnext)类库项目的引用到我的vnext Web应用程序。如果我按照以下步骤：

>创建一个新的Web应用程序项目
>从project.json中删除“dnxcore50”框架
>为普通类库添加一个新项目
>手动将类库项目移动到/ src文件夹中(否则我得到错误“依赖关系MyClassLibrary1> = 1.0.0- *无法解析。”)
>添加对这个类库的引用

现在它建立好了，但是如果我尝试添加“使用MyClassLibrary1”，它表示MyClassLibrary1在当前上下文中不存在。

如果我然后将类库更改为目标.NET 4客户端配置文件(默认情况下为4.6)，则它可以正常工作，但是.NET 4 full或4.5不起作用。我需要4.5或更高版本，因为我需要参考需要这个的各种包。理想情况下，一切都只能达到4.6。

这是我的project.json文件：
