我正在尝试使用JSON列创建一个迁移。以下是我尝试过的：

    [Column(TypeName = "Jsonb")]
    public string Data { get; set; }

    [Column(TypeName = "Json")]
    public string Data { get; set; }

    modelBuilder.Entity<Member>().Property(p => p.Data).HasColumnType("Json");

    modelBuilder.Entity<Member>().Property(p => p.Data).HasColumnType("Jsonb");

什么都不起作用，这里有一个例外：

序列在System.Data.Entity.Utilities.DbProviderManifestExtensions.GetStoreTypeFromName(DbProviderManifest System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.PrimitivePropertyConfiguration.ConfigureColumn(EdmProperty列的System.Linq.Enumerable.SingleTSource处不包含匹配元素，在System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.PrimitivePropertyConfiguration.Configure(EdmProperty列中包含字符串名称)，在System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.PrimitivePropertyConfiguration.Configure(EdmProperty列中包含EntityType表，在System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.PrimitivePropertyConfiguration.Configure(EdmProperty列中包含DbProviderManifest providerManifest，在EntityType表中，在DbProviderManifest providerManifest中，在布尔allowOverride中包含匹配元素。在System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.PrimitivePropertyConfiguration.<>c__DisplayClass4.b__3(Tuple2 pm) at System.Data.Entity.Utilities.IEnumerableExtensions.Each[T](IEnumerable1 ts，Action1 action) at System.Data.Entity.ModelConfiguration.Configuration.Properties.Primitive.PrimitivePropertyConfiguration.Configure(IEnumerable1 propertyMappings，DbProviderManifest providerManifest，Boolean，Boolean ) at System.Data.Entity.ModelConfiguration.Configuration.Types.StructuralTypeConfiguration.ConfigurePropertyMappings(IList1 propertyMappings, DbProviderManifest providerManifest, Boolean allowOverride) at System.Data.Entity.ModelConfiguration.Configuration.Types.EntityTypeConfiguration.ConfigurePropertyMappings(DbDatabaseMapping databaseMapping, EntityType entityType, DbProviderManifest providerManifest, Boolean allowOverride) at System.Data.Entity.ModelConfiguration.Configuration.Types.EntityTypeConfiguration.Configure(EntityType entityType, DbDatabaseMapping databaseMapping, DbProviderManifest providerManifest) at System.Data.Entity.ModelConfiguration.Configuration.ModelConfiguration.ConfigureEntityTypes(DbDatabaseMapping databaseMapping, ICollection1 entitySets，DbProviderManifest providerManifest) at System.Data.Entity.ModelConfiguration.Configuration.ModelConfiguration.Configure(DbDatabaseMapping databaseMapping，DbProviderManifest providerManifest)( System.Data.Entity.DbModelBuilder.Build(DbConnection providerConnection) ( DbProviderInfo providerInfo) ( System.Data.Entity.Internal.RetryLazy2.GetValue(TInput input) at System.Data.Entity.Internal.LazyInternalContext.InitializeContext() at System.Data.Entity.Internal.InternalContext.GetEntitySetAndBaseTypeForType(Type entityType) at System.Data.Entity.Internal.Linq.InternalSet1.Initialize() at System.Data.Entity.Internal.Linq.InternalSet1.get_InternalContext() at System.Data.Entity.Internal.Linq.InternalSet1.get_Local() at System.Data.Entity.DbSet`1.get_Local() at System.Data.Entity.DbModelBuilderExtensions.RegisterUserAccountChildTablesForDeleteTKey,TAccount,TUserClaim,TLinkedAccount,TLinkedAccountClaim,TPasswordResetSecret,TTwoFactorAuthToken,TUserCertificate in c:\ballen\github\brockallen\BrockAllen.MembershipReboot\src\BrockAllen.MembershipReboot.Ef\DbModelBuilderExtensions.cs:line 26

这是我的配置：

<package id="EntityFramework" version="6.1.1" targetFramework="net452" />
<package id="EntityFramework6.Npgsql" version="3.1.1" targetFramework="net452" />
<package id="Npgsql" version="3.1.6" targetFramework="net452" />
