转 ef中使用mysql步骤–Entity Framework 6 with MySql

原文：http://lvasquez.github.io/2014/11/18/EntityFramework-MySql/

For the Entity Framework 6 support we need to have this requirements

• MySQL Connector/Net 6.8.x
• MySQL Server 5.1 or above
• Entity Framework 6 assemblies
• .NET Framework 4.0 or above

I will use the concept of DataBase First but without using the Visual Studio wizard to create the Edmx file, so instead of that, I will do it manually. I will create a Console Application, so first install the Entity Framework via Nuget Package

Install-Package EntityFramework

Install-Package MySql.Data.Entity.EF6Add the connection string in the app.confing
the app.confing should be like this

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
