Mono Entity Framework 6 MySQL
This is because you don't seem to have the MySql ADO.NET provider configured. Take a look at my blogpost about using EF6 and MySql on Mono which shows how to resolve this exact issue (note that I wrote this post for pre-release EF6 version and the issues I hit on the road should be now fixed). Note that in the post I used DevArt MySql provider so you will have to find the correct entries to use for your provider. Also take a look at this stackoverflow post - Custom .NET Data Providers - which provides details on registering ADO.NET providers (you are most interested in DbProviderFactories part because this is what you are missing)

I have developed a project with Entity Framework 6 that use a
MySQL
as database.. On my windows system the project is working. Now I tried to move that project on my linux machine. In order to run the project I added theMySQL
dll to the GAC and to machine config. All needed dlls are also located in the project folder. When the Entity Framework access the database I am getting the following error:System.Configuration.ConfigurationErrorsException: Failed to find or load the registered .Net Framework Data Provider. at System.Data.Common.DbProviderFactories.GetFactory (System.Data.DataRow providerRow) [0x00000] in <filename unknown>:0 <?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" /> <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> </configSections> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> </startup> <connectionStrings> <add name="CashDeskServerContext" providerName="MySql.Data.MySqlClient" connectionString="server=localhost; port=3306;database=ServerContext;uid=root;password=password;Convert Zero Datetime=True"/> <add name="AuditLogContext" providerName="MySql.Data.MySqlClient" connectionString="server=localhost; port=3306;database=AuditLogContext;uid=root;password=password;Convert Zero Datetime=True"/> </connectionStrings> <entityFramework> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" /> <providers> <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" /> <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" /> </providers> </entityFramework> </configuration>
Any ideas?
