[英]Configuration Error: Error for provider in web.config
我正在从entityframework 6.1.0迁移到entityframework 5.0.0。 我已经成功安装了EntityFramework 5.0.0。
现在我在web.config中遇到问题。
这是我的web.config:
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<appSettings>
<add key="webpages:Version" value="2.0.0.0" />
<add key="webpages:Enabled" value="false" />
<add key="PreserveLoginUrl" value="true" />
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
<connectionStrings>
<add name="MusicStoreEntities" connectionString="data source=(LocalDb)\v11.0;initial catalog=MvcMusicStore;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\MvcMusicStore.mdf" providerName="System.Data.SqlClient" />
<system.webServer>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
<remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />

</handlers>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework">
<parameters>
<parameter value="v11.0" />
</parameters>
</defaultConnectionFactory>
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
EF 6.1.0之前没有这个问题。
我进行了很多搜索,但是找不到解决我问题的方法。
谢谢...
去掉
<providers>
<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
这是EF网站上有关EF 6自己唯一需要的提供商的更多信息。
确保已安装LocalDb NuGet软件包:
Install-Package Microsoft.AspNet.Providers.LocalDb
