[英]Entity Framework defaultConnectionFactory for MySQL
The below configuration works fine when I specify the connectionString name as a parameter to the base constructor. 当我将connectionString名称指定为基础构造函数的参数时,以下配置正常工作。 Because I want to be able to change the default provider later on without recompiling, I want to set it in my
app.config
instead, but I have no idea what to provide as type
for defaultConnectionFactory
. 因为我希望以后能够在不重新编译的情况下更改默认提供程序,所以我想在
app.config
设置它,但我不知道提供什么作为defaultConnectionFactory
type
。
<connectionStrings>
<add name="MySQL" providerName="MySql.Data.MySqlClient" connectionString="SERVER=localhost;DATABASE=abc;UID=root;PASSWORD=;" />
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, EntityFramework"></defaultConnectionFactory>
<providers>
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>
</providers>
</entityFramework>
Exception: 例外:
Failed to set Database.DefaultConnectionFactory to an instance of the 'MySql.Data.Entity.MySqlConnectionFactory, EntityFramework' type as specified in the application configuration.
无法将Database.DefaultConnectionFactory设置为应用程序配置中指定的“MySql.Data.Entity.MySqlConnectionFactory,EntityFramework”类型的实例。 See inner exception for details.
请参阅内部异常了解详细信
Inner exception (translated, VS is set to English but some messages are still in my language): 内部异常(已翻译,VS设置为英语但某些消息仍为我的语言):
Could not load type "MySql.Data.Entity.MySqlConnectionFactory" in assembly "EntityFramework"
无法在程序集“EntityFramework”中加载“MySql.Data.Entity.MySqlConnectionFactory”类型
The documentation states that the assembly name follows after the colon, thus I also tried MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6
, giving me this exception: 文档说明程序集名称
MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6
冒号,因此我也尝试了MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6
,给我这个例外:
Format of the initialization string does not conform to specification starting at index 0.
初始化字符串的格式不符合从索引0开始的规范。
I'm using EF6, MySql.Data & MySql.Data.Entity.EF6 6.8.3.0. 我正在使用EF6,MySql.Data和MySql.Data.Entity.EF6 6.8.3.0。
The name
property of the connectionString must be the same as your context. connectionString的
name
属性必须与您的上下文相同。 This works fine: 这很好用:
<connectionStrings>
<add name="NAMEOFYOURCONTEXT" providerName="MySql.Data.MySqlClient" connectionString="Server=localhost;Database=abc;Uid=root;Pwd='';" />
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6"></defaultConnectionFactory>
<providers>
<provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6"></provider>
</providers>
</entityFramework>
