I've been spending the past 3 days trying to fix this problem I'm encountering - it's driving me insane... I'm not quite sure what is causing this bug - here are the details:

MVC4 + Entity Framework 4.4 + MySql + POCO/Code First

I'm setting up the above configuration .. here are my classes:

namespace BTD.DataContext
{
public class BTDContext : DbContext
{

    public BTDContext()
        : base("name=BTDContext")
    {

    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        //modelBuilder.Conventions.Remove<System.Data.Entity.Infrastructure.IncludeMetadataConvention>();
    }

    public DbSet<Product> Products { get; set; }

    public DbSet<ProductImage> ProductImages { get; set; }        


}
}

namespace BTD.Data
{
[Table("Product")]
public class Product
{
    [Key]
    public long ProductId { get; set; }

    [DisplayName("Manufacturer")]
    public int? ManufacturerId { get; set; }

    [Required]
    [StringLength(150)]
    public string Name { get; set; }

    [Required]
    [DataType(DataType.MultilineText)]
    public string Description { get; set; }

    [Required]
    [StringLength(120)]
    public string URL { get; set; }

    [Required]
    [StringLength(75)]
    [DisplayName("Meta Title")]
    public string MetaTitle { get; set; }

    [DataType(DataType.MultilineText)]
    [DisplayName("Meta Description")]
    public string MetaDescription { get; set; }

    [Required]
    [StringLength(25)]
    public string Status { get; set; }

    [DisplayName("Create Date/Time")]
    public DateTime CreateDateTime { get; set; }

    [DisplayName("Edit Date/Time")]
    public DateTime EditDateTime { get; set; }
}

[Table("ProductImage")]
public class ProductImage
{
    [Key]
    public long ProductImageId { get; set; }

    public long ProductId { get; set; }

    public long? ProductVariantId { get; set; }

    [Required]
    public byte[] Image { get; set; }

    public bool PrimaryImage { get; set; }

    public DateTime CreateDateTime { get; set; }

    public DateTime EditDateTime { get; set; }

}
}

Here is my web.config setup...

<connectionStrings>
<add name="BTDContext" connectionString="Server=localhost;Port=3306;Database=btd;User Id=root;Password=mypassword;" providerName="MySql.Data.MySqlClient" />
</connectionStrings>

1. The database AND tables already exist...
2. I'm still pretty new with mvc but was using this tutorial

The application builds fine.. however when I try to add a controller using Product (BTD.Data) as my model class and BTDContext (BTD.DataContext) as my data context class I receive the following error:

Unable to retrieve metadata for BTD.Data.Product using the same DbCompiledModel to create context against different types of database servers is not supported. Instead, create a separate DbCompiledModel for each type of server being used.

I am at a complete loss - I've scoured google with almost every different variation of that error message above I can think of but to no avail.

Here are the things i can verify...

1. MySql is working properly
2. I'm using MySql Connector version 6.5.4 and have created other ASP.net web forms + entity framework applications with ZERO problems

I have also tried including/removing this in my web.config:

<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=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>

I've literally been working on this bug for days - I'm to the point now that I would be willing to pay someone to solve it.. no joke... I'd really love to use MVC 4 and Razor - I was so excited to get started on this, but now i'm pretty discouraged - I truly appreciate any help/guidance on this!

Also note - i'm using Entityframework from Nuget...

Another Note

I was using the default visual studio template that creates your MVC project with the account pages and other stuff. I JUST removed all references to the added files because they were trying to use the "DefaultConnection" which didn't exist - so i thought those files may be what was causing the error - however still no luck after removing them -

I just wanted to let everyone know i'm using the visual studio MVC project template which pre-creates a bunch of files. I will be trying to recreate this all from a blank MVC project which doesn't have those files - i will update this once i test that

Other References

It appears someone else is having the same issues I am - the only difference is they are using sql server - I tried tweaking all my code to follow the suggestions on this stackoverflow question/answer here but still to no avail
