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

Question

Good Day Developers,
Please I updated my .Net5 to .Net6 and I have this errors on adding migration:

System.MissingMethodException: Method not found: 'System.Type Microsoft.EntityFrameworkCore.Metadata.ITypeBase.get_ClrType()'. at Abp.EntityFrameworkCore.AbpDbContext.OnModelCreating(ModelBuilder modelBuilder) at Abp.Zero.EntityFrameworkCore.AbpZeroCommonDbContext3.OnModelCreating(ModelBuilder modelBuilder) at Abp.Zero.EntityFrameworkCore.AbpZeroDbContext4.OnModelCreating(ModelBuilder modelBuilder) at Microsoft.EntityFrameworkCore.Infrastructure.ModelCustomizer.Customize(ModelBuilder modelBuilder, DbContext context) at Microsoft.EntityFrameworkCore.Infrastructure.ModelSource.CreateModel(DbContext context, IConventionSetBuilder conventionSetBuilder, ModelDependencies modelDependencies) at Microsoft.EntityFrameworkCore.Infrastructure.ModelSource.GetModel(DbContext context, ModelCreationDependencies modelCreationDependencies, Boolean designTime) at Microsoft.EntityFrameworkCore.Internal.DbContextServices.CreateModel(Boolean designTime) at Microsoft.EntityFrameworkCore.Internal.DbContextServices.get_Model() at Microsoft.EntityFrameworkCore.Infrastructure.EntityFrameworkServicesBuilder.<>c.b__8_4(IServiceProvider p) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor2.VisitCallSiteMain(ServiceCallSite callSite, TArgument argument) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitCache(ServiceCallSite callSite, RuntimeResolverContext context, ServiceProviderEngineScope serviceProviderEngine, RuntimeResolverLock lockType) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitScopeCache(ServiceCallSite callSite, RuntimeResolverContext context) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor2.VisitCallSite(ServiceCallSite callSite, TArgument argument) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitConstructor(ConstructorCallSite constructorCallSite, RuntimeResolverContext context) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteVisitor`2.VisitCallSiteMain(ServiceCallSite callSite, TArgument argument) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitCache(ServiceCallSite callSite, RuntimeResolverContext context, ServiceProviderEngineScope serviceProviderEngine, RuntimeResolverLock lockType) at Microsoft.Extensions.DependencyInjection.ServiceLookup.CallSiteRuntimeResolver.VisitScopeCacMicrosoft.EntityFrameworkCore.Metadata.ITypeBase.get_ClrType()'.

I have check 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. Please I need help.

This error occurs when you have different versions of EntityFrameworkCore and NetCore in your project, please be sure to install the version of EntityFramework compatible with your NetCore 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 :) — Jonathan Carroll, Mar 23 '23 at 14:24
