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-*"
            
        
    

任何机构可以帮助我吗？

我的新工作project.json

 
    "version": "1.0.0-*", 
    "dependencies": 
     

    , 
    "frameworks" : 
     
        "dnx451" : 
        
            "frameworkAssemblies": 
            
                    "System.Xml": "4.0.0.0"
            
        , 
        "dnxcore50" : 
         
            "dependencies": 
             
                "System.Console": "4.0.0-beta-*",
                "System.Xml.XmlSerializer": "4.0.10-beta-*"
             
        
     

【参考方案1】：

尝试将System.Xml.XmlSerializer 移动到 dnxcore50 依赖项。 dnx451 已经有了XmlSerializer 类，所以它不需要System.Xml.XmlSerializer 包（依赖于System.Collections 包）

【讨论】：

感谢您的帮助。现在它可以工作了，但我必须在dnx451 中将System.Xml 添加到frameworkAssemblies。
