Entity Framework defaultConnectionFactory for MySQL
The name
property of the connectionString must be the same as your context. This works fine:
<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>

The below configuration works fine when I specify the connectionString name as a parameter to the base constructor. 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 astype
fordefaultConnectionFactory
.<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:
Failed to set Database.DefaultConnectionFactory to an instance of the 'MySql.Data.Entity.MySqlConnectionFactory, EntityFramework' type as specified in the application configuration. See inner exception for details.
Inner exception (translated, VS is set to English but some messages are still in my language):
Could not load type "MySql.Data.Entity.MySqlConnectionFactory" in assembly "EntityFramework"
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:Format of the initialization string does not conform to specification starting at index 0.
I'm using EF6, MySql.Data & MySql.Data.Entity.EF6 6.8.3.0.
