To establish a connection between Entity Framework 6 and MySQL, follow these steps:
<add name="mysqlCon" connectionString="Server=localhost;Database=dbName;Uid=username;Pwd=password" providerName="MySql.Data.MySqlClient" />
<defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6" /> <providers> <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" /> </providers>
<add name="mysqlCon" connectionString="Server=localhost;Database={0};Uid=username;Pwd=password" providerName="MySql.Data.MySqlClient" />
public class ApplicationDbContext : DbContext { public ApplicationDbContext(string dbName) : base(GetConnectionString(dbName)) { } public static string GetConnectionString(string dbName) { var connString = ConfigurationManager.ConnectionStrings["mysqlCon"].ConnectionString.ToString(); return String.Format(connString, dbName); } }
public class MigrationsContextFactory : IDbContextFactory<ApplicationDbContext> { public ApplicationDbContext Create() { return new ApplicationDbContext("developmentdb"); } }
This allows you to pass a dynamic connection string to the entity framework context, enabling you to easily switch between multiple identical database schemas based on account.
