我尝试了不同的方法，但没有一个对我有帮助。

这是我的project.json 文件

{
    "version": "1.0.0-*",
    "dependencies":
    {
        "System.Xml.XmlSerializer": "4.0.10-beta-*"
    },
    "frameworks":
    {
        "dnx451":
        {
            "dependencies":{}
        },
        "dnxcore50":
        {
            "dependencies":
            {
                "System.Console": "4.0.0-beta-*"
            }
        }
    }
}

有人可以帮助我吗？

}

Answer 1

尝试将 System.Xml.XmlSerializer 移动到 dnxcore50 依赖项。 dnx451 已经具有 XmlSerializer 类，因此它不需要 System.Xml.XmlSerializer 包(这取决于 System.Collections 包) )
