请考虑使用 app.config 将程序集“System.Data, Culture=neutral, PublicKeyToken=969db8053d3322ac, Retargetable=Yes”从版本“2.0.0.0”[]重新映射

做mobile开发编译输出提示：

请考虑使用 app.config 将程序集“System.Data, Culture=neutral, PublicKeyToken=969db8053d3322ac, Retargetable=Yes”从版本“2.0.0.0”[]重新映射到版本“3.5.0.0”

 

只需在项目中加入 App.Config 文件，文件内容如下即可：

 

 
   
    
   <? 
   xml version="1.0" encoding="utf-8"  
   ?>

   > 
   
                 
   < 
   assemblyIdentity

   = "System.Data" 
    culture 
   = "neutral" 
    publicKeyToken 
   = "969db8053d3322ac" 
    Retargetable 
   = "Yes" 
   /> 
   
                 
   <

   oldVersion

    newVersion

   /> 
   
             
   </

   <

   < 
   bindingRedirect  
   oldVersion 
   = "2.0.0.0" 
    newVersion

   </

个人猜测，可能是运行时检测到安装有多个版本，推荐用新的版本运行.
