Thank you for choosing this package.

The BenBurgers.InternationalStandards.Iso.EFCore.SqlServer package contains Entity Framework Core SQL Server features for codes and features that belong to standards of the International Organization for Standardization (ISO).

The International Organization for Standardization (ISO) is an international standard development organization composed of representatives from the national standards organizations of member countries. The organization develops and publishes standardization in all technical and nontechnical fields other than electrical and electronic engineering.[^1]

You are kindly encouraged to buy the standards you use at the ISO Store in order to fund their mission.

GitHub Sponsors

If you like my contributions, please have a look at my GitHub Sponsors profile. My open source contributions are available free of charge (but subject to licenses) and the contributions are made entirely in my free time, but sponsorship would be sincerely appreciated. Thank you.

If possible, please also buy a standard from the respective Maintenance Agency or ISO itself to cover the costs of the Maintenance Agencies and the ISO in maintaining the standards.


These are the packages that concern the ISO standards:

Name Description
BenBurgers.InternationalStandards.Iso The main package with the codes and metadata.
BenBurgers.InternationalStandards.Iso.EFCore Features for storing codes using Entity Framework Core.
BenBurgers.InternationalStandards.Iso.EFCore.SqlServer Features for storing codes using Entity Framework Core and SQL Server.
BenBurgers.InternationalStandards.Iso.IO Features for reading Code Tables from authorities.
BenBurgers.InternationalStandards.Iso.Json Features for serializing and deserializing codes in JSON.

Please refer to NuGet to download the packages and GitHub for the source code.


Supported ISO standards

The following are the currently supported ISO standards.

Name Description
ISO 639 Language codes
ISO 3166 Country codes
ISO 4217 Currency codes


Property builders for Alpha2 and Alpha3 property values may be found in the namespace:

  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Metadata.Builders

These are extension methods that may be used in the fluent configuration of entities for Entity Framework Core.

ISO 639 language codes

Property builders and a Database Context for migrations and queries may be found in the namespaces:

  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Iso639
  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Iso639.Metadata.Builders

ISO 3166 country codes

Property builders and a Database Context for migrations and queries may be found in the namespaces:

  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Iso3166
  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Iso3166.Metadata.Builders

ISO 4217 currency codes

Property builders and a Database Context for migrations and queries may be found in the namespaces:

  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Iso4217
  • BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Iso4217.Metadata.Builders



In order to access migrations through the dotnet-ef tool, it is possible to create your own Migrations assembly and inherit the class BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Design.IsoDesignTimeDbContextFactory, with a particular Database Context for the desired standard as its type parameter.

An inherited class of BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Design.IsoDesignTimeServices will be necessary for generating the C# migrations.


The configuration options for the Database Context Factory may be provided by overriding the IsoSqlServerOptions property, or command line arguments with the dotnet-ef tool.

The configuration parameters may be found in BenBurgers.InternationalStandards.Iso.EFCore.SqlServer.Configuration.IsoSqlServerOptions.

Multiple Database Contexts for multiple ISO standards

If there are multiple Database Contexts, it will be necessary to tell the dotnet-ef tool which one to generate migrations for in a particular run.

The migrations will populate a specified database with a lookup table for any supported standard. The lookup table will be read-only for public database users.
