Question

我正在尝试使用我的模型并从中创建数据库。当我尝试基于模型生成数据库时，我收到以下错误：

运行转换：System.InvalidOperationException：由名为'CsdlToSsdlAndMslActivity'的活动生成的SSDL无效，并且有以下错误：
没有为ADO.NET提供程序找到具有不变名称“MySql.Data.MySqlClient”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。有关详细信息，请参阅http://go.microsoft.com/fwlink/?LinkId=260882。

如果有任何帮助，以下内容包含我的App.config：

GetPurchases()

我知道问题出在基于错误消息的<?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />  </configSections> <connectionStrings> <add name="SomeDatabase" providerName="MySql.Data.MySqlClient" connectionString="password=user;server=192.168.0.114;uid=hello;database=example;persistsecurityinfo=True;" /> </connectionStrings> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> </startup> <entityFramework codeConfigurationType="MySql.Data.Entity.MySqlEFConfiguration, MySql.Data.Entity.EF6"> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" /> <providers> <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider> <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> </providers> </entityFramework> <system.data> <DbProviderFactories> <remove invariant="MySql.Data.MySqlClient" /> <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> </DbProviderFactories> </system.data> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"></assemblyBinding> </runtime> </configuration>，但我似乎无法弄清楚它希望我做什么。我已将MySql.Data.MySqlClient，MySql.Data和MySql.Data.Entity.EF6添加到项目中。

任何人都知道如何解决这个问题？

在此之前我遇到了同样的问题。我设法通过创建一个全新的项目来解决它。

转到Manage NuGet Packages，安装EntityFramework，MySql.ConnectorNET.Data和MySql.ConnectorNET.Entity。
使用此处显示的连接字符串<add name="SomeDatabase" providerName="MySql.Data.MySqlClient" connectionString="server=localhost;port=3306;database=example;uid=hello;password=user"/>
在DbContext类中添加[DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))]。

EntityFramework 6不适用于MySql
