错误：没有为ADO.NET找到实体框架提供程序 [英] Error : no entity framework provider found for the ADO.NET

问题描述

没有为ADO.NET提供程序找到具有不变名称System.Data.SqlClient的实体框架提供程序。确保提供程序已在应用程序配置文件的entityFramework部分中注册。

Iam使用EntityFrameWork并且插入记录时出错

我尝试过：



在BLL Layer App.Config：

No Entity Framework provider found for the ADO.NET provider with invariant name 'System.Data.SqlClient'. Make sure the provider is registered in the 'entityFramework' section of the application config file.

推荐答案

Try adding the following runtime assembly bindings:

< runtime>

< assemblyBinding xmlns =urn：schemas -microsoft-com：asm.v1>

< dependentAssembly>

< assemblyIdentity name =EntityFrameworkpublicKeyToken =b77a5c561934e089culture =neutral/ >

< bindingRedirect oldVersion =0.0.0.0-6.0.0.0newVersion =6.0.0.0/>

< / dependentAssembly>

< / assemblyBinding>

< / runtime>

<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
