  Error: iisexpress.exe - Assertion failed.

  Nov 22, 2012 02:52 PM|LINK

  Hi there,

  I am trying to learn mvc. I use Pluralsight training videos in this site(asp.net). In this video we created an DBContext Class called OdeToFoodDb:

  public class OdeToFoodDb: DbContext
      {
          public DbSet<Restaurant> Restaurants { get; set; }
          public DbSet<Review> Reviews { get; set; }
  
          protected override void OnModelCreating(System.Data.Entity.ModelConfiguration.ModelBuilder modelBuilder)
          {
              modelBuilder.Entity<Restaurant>()
                  .HasMany(resturant => resturant.Reviews)
                  .WithRequired(review => review.Resturant);
              base.OnModelCreating(modelBuilder);
          }
      }

  The problem is when i create a new object of this class:

   OdeToFoodDb _db = new OdeToFoodDb();

  I get following error:

  iisexpress.exe - Assertion failed.

  Expression: primitiveType != null

  Description: Assertion failed: primitiveType != null
  
  Please help me

  Thanks

  Please excuse me for bad and poor English.

  public DbSet<Restaurant> Restaurants { get; set; }
          public DbSet<Review> Reviews { get; set; }

  Hi,

  Can you give the full codes of your Restaurant as well as Review's codes?

  And what's more——Your web.config, please.

  Hi Decker Dong-MSFT and thank you for your replay.

  I just updated my Entity Framework version to 5.0.0 and it works fine!.

  By the way i change a little in entity framework namespace. Because entity framework 5 had a little change in its namespaces.

  Please excuse me for bad and poor English.
