I'm building a web app using ASP.NET MVC. I also intend to access a remote MySQL database. Would like to keep Entity Framework.

What I am trying to do is access the context within my controller. This worked without an issue using the vanilla database solution. However, now that I am accessing a remote database, it doesn't seem to be working properly. The connection to the database is valid—it actually migrates and seeds properly. But, when I try accessing a member of the context, the app fails.

Web.config

<connectionStrings>

    <remove name="DBName" />

    <add name="DBName" connectionString="server=1.2.3.4;port=1234;user id=DBAdmin;password=DBPass;database=DBName;integrated security=True" providerName="MySQL.Data.MySqlClient" />

</connectionStrings>

<system.data>

    <DbProviderFactories>

        <remove invariant="MySql.Data.MySqlClient" />

        <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.9.9, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />

    </DbProviderFactories>

</system.data>

<entityFramework>

    <defaultConnectionFactory type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6">

        <parameters>

            <parameter value="v11.0" />

        </parameters>

    </defaultConnectionFactory>

    <providers>

        <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.9.9, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />

        <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />

    </providers>

</entityFramework>

Context.cs

[DbConfigurationType (typeof (MySql.Data.Entity.MySqlEFConfiguration))]

public class Context : DbContext {

    public Context () : base ("name=DBName") {

        Database.SetInitializer (new MigrateDatabaseToLatestVersion <Context, System.Data.Entity.Migrations.DbMigrationsConfiguration <Context>> ());

    }



    public DbSet<Software> Softwares { get; set; }

}

SoftwareController

public class SoftwareController : Controller {

    public ActionResult Index() {

        using (Context context = new Context ()) {

            List<Software> softwares = context.Softwares.ToList ();



            return View (softwares);

        }

    }

}

Error

The given key was not present in the dictionary.

Source Error

List softwares = context.Softwares.ToList ();
