TypeInitializationException occured in 'System.Data.Entity.dll' - type initializer 'ExtentPlaceholderCreator'

asp.net-mvc c# entity-framework

Question

Running Visual Studio 2013 ASP.NET MVC 4 Entity Framework (EF) 5

After running my project, when navigating to the 'create' page. I try to post information to local mysql database, this exception is thrown...

An exception of type 'System.TypeInitializationException' occurred in System.Data.Entity.dll but was not handled in user code

Additional information: The type initializer for 'ExtentPlaceholderCreator' threw an exception.

at this location in my AuctionController.cs file

[HttpPost]
public ActionResult Create([Bind(Exclude="CurrentPrice")]Models.Auction auction)
{
    if (ModelState.IsValid)
    {
        // Save to the database
        var db = new MvcAuction.Models.AuctionsDataContext();
        db.Auctions.Add(auction);

        db.SaveChanges();

        return RedirectToAction("Index");
    }

    return Create();
}

Click here to see screenshot of error

This is my Database Context class file:

 namespace MvcAuction.Models
{
    public class AuctionsDataContext : System.Data.Entity.DbContext
    {
        public System.Data.Entity.DbSet<Auction> Auctions { get; set; }
    }
}

I think the issue is going wrong in my web.config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-MvcAuction-20121126103244;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-MvcAuction-20121126103244.mdf" providerName="System.Data.SqlClient" />
    <add name="MvcAuction.Models.AuctionsDatacontext" connectionString="Data Source=(LocalDb)\v11.0;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\MvcAuction.Models.AuctionsDatacontext.mdf" providerName="System.Data.SqlClient" />
  </connectionStrings>

I am following this tutorial: https://www.lynda.com/ASP-NET-tutorials/Persisting-data-Entity-Framework-code-first/109762/120303-4.html?autoplay=true

The teacher is using Visual Studio 2012, his works fine:D

I do not know why this is holding me up. Nor what exactly it is asking, to my knowledge there were no breaking changes from Visual Studio 2012 to 2013.

Ok I found the solution here:

Entity Framework cannot update database

First of all, if I would have post the entire stack trace it would have been more helpful:

Notice the last InnerException: System.EntryPointNotFoundException. After researching this error (I didn't see it earlier) I found this code to add to my web.config file and it worked!

    <dependentAssembly>
      <assemblyIdentity name="Microsoft.SqlServer.Types" publicKeyToken="89845dcd8080cc91" />

I believe it has something to do with an sql update breaking something. This article & comments were also helpful: http://www.networksteve.com/forum/topic.php/Entity_framework_can't_make_updates_in_db_(missing_entry_point_S/?TopicId=97401&Posts=2

p.s: I am very new to stackoverflow, if this question and answer should be discarded in favor of the one I referenced that's fine.
