System.MissingMethodException: Method not found: 'System.Type Microsoft.EntityFrameworkCore.Metadata.ITypeBase.get_ClrType()'

Question

Please I updated my .NET 5 to .NET 6 and I have this errors on adding migration:

System.MissingMethodException: Method not found: 'System.Type Microsoft.EntityFrameworkCore.Metadata.ITypeBase.get_ClrType()'.

I have checked all my Microsoft.EntityFrameworkCore packages and they are of the same version. Is pointing this version of my code,

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

            modelBuilder.Entity<BinaryObject>(b =>
            {
                b.HasIndex(e => new { e.TenantId });
            });

            modelBuilder.Entity<ChatMessage>(b =>
            {
                b.HasIndex(e => new { e.TenantId, e.UserId, e.ReadState });
                b.HasIndex(e => new { e.TenantId, e.TargetUserId, e.ReadState });
                b.HasIndex(e => new { e.TargetTenantId, e.TargetUserId, e.ReadState });
                b.HasIndex(e => new { e.TargetTenantId, e.UserId, e.ReadState });
            });

            modelBuilder.Entity<Friendship>(b =>
            {
                b.HasIndex(e => new { e.TenantId, e.UserId });
                b.HasIndex(e => new { e.TenantId, e.FriendUserId });
                b.HasIndex(e => new { e.FriendTenantId, e.UserId });
                b.HasIndex(e => new { e.FriendTenantId, e.FriendUserId });
            });

            modelBuilder.Entity<Tenant>(b =>
            {
                b.HasIndex(e => new { e.SubscriptionEndDateUtc });
                b.HasIndex(e => new { e.CreationTime });
            });

            modelBuilder.Entity<SubscriptionPayment>(b =>
            {
                b.HasIndex(e => new { e.Status, e.CreationTime });
                b.HasIndex(e => new { PaymentId = e.ExternalPaymentId, e.Gateway });
            });

            modelBuilder.Entity<SubscriptionPaymentExtensionData>(b =>
            {
                b.HasQueryFilter(m => !m.IsDeleted)
                    .HasIndex(e => new { e.SubscriptionPaymentId, e.Key, e.IsDeleted })
                    .IsUnique();
            });

            modelBuilder.Entity<UserDelegation>(b =>
            {
                b.HasIndex(e => new { e.TenantId, e.SourceUserId });
                b.HasIndex(e => new { e.TenantId, e.TargetUserId });
            });

            modelBuilder.ConfigurePersistedGrantEntity();
        }

Is there thing I can implement to solve this issue.

This error occurs when you have different versions of Entity Framework Core and .NET Core in your project, please be sure to install the version of Entity Framework compatible with your .NET Core version.

For .NET 5.0 the packages are:

Microsoft.EntityFrameworkCore.Design [5.0.10]
Microsoft.EntityFrameworkCore.SqlServer [5.0.10]
Microsoft.EntityFrameworkCore.Tools [5.0.10]

For .NET 6.0 you can install:

Microsoft.EntityFrameworkCore.Design [6.0.10]
Microsoft.EntityFrameworkCore.SqlServer [6.0.10]
Microsoft.EntityFrameworkCore.Tools [6.0.10]

I'm upgrading from 6.0 to 7.0 and ran into this issue. Make sure in addition to this you also upgrade the EFCore.NamingConventions package if you're using it :)

Also got this error when I forgot to update Z.EntityFramework.Plus.EFCore when I went from 6 to 7.

OK. Well, I'm in the situation where I'm having to maintian cross-project integration tests which are failing as only half the company has had time to upgrade to .NET 8. The tests are now disabled, which is seems as a high-risk/high-impact liability. So how would one use EFCore N-1 for one half (arrangement) of the integration test and EFCore N for the other (assert) half?

If you have only updated your EntityFrameworkCore nuget versions, you may encounter such an error.

Some of your nuget packages may have an old EntityFrameworkCore version.

Make sure that all your nuget packages are up to date.

For example, I upgraded my project and EntityFrameworkCore versions to version 8. The EntityFrameworkCore.EncryptColumn package was out of date and I was encountering this error. I got rid of this error with the preview version of the package.
