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:

 

代码
<? xml version="1.0" encoding="utf-8"  ?>
< configuration >
    
< runtime >
        
< assemblyBinding >
            
< dependentAssembly >
                
< assemblyIdentity  name = "System.Data"  culture = "neutral"  publicKeyToken = "969db8053d3322ac"  Retargetable = "Yes" />
                
< bindingRedirect  oldVersion = "2.0.0.0"  newVersion = "3.5.0.0" />
            
</ dependentAssembly >
            
< dependentAssembly >
                
< assemblyIdentity  name = "System"  culture = "neutral"  publicKeyToken ="969db8053d3322ac"  Retargetable = "Yes" />
                
< bindingRedirect  oldVersion = "2.0.0.0"  newVersion = "3.5.0.0"   />
            
</ dependentAssembly >
            
< dependentAssembly >
                
< assemblyIdentity  name = "System.Xml"  culture = "neutral"  publicKeyToken ="969db8053d3322ac"  Retargetable = "Yes" />
                
< bindingRedirect  oldVersion = "2.0.0.0"  newVersion = "3.5.0.0"   />
            
</ dependentAssembly >
        
</ assemblyBinding >
    
</ runtime >
</ configuration >

 

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.
