Migration Guides

There are a few breaking changes in this version that may affect your application. Please see the following migration documents, if you are upgrading from v8.x or earlier:

What's New with ABP Framework 8.1?

In this section, I will introduce some major features released in this version. Here is a brief list of titles explained in the next sections:

  • Introducing the ExposeKeyedServiceAttribute
  • Custom Menu Component Support for MVC UI
  • Introducing the DisableAbpFeaturesAttribute

Introducing the ExposeKeyedServiceAttribute

Keyed dependency injection (DI) services were added to the built-in DI container as a new feature with .NET 8.0. This is an important feature, which allows for registering and retrieving DI services using keys/names.

In this version, we have introduced the ExposeKeyedServiceAttribute to allow you to automatically register keyed services by conventions:

public class TaxCalculator: ICalculator, ITaxCalculator, ICanCalculate, ITransientDependency

In the example above, the TaxCalculator class exposes the ITaxCalculator interface with the key taxCalculator and the ICalculator interface with the key calculator.

Thanks to that, then you can use the FromKeyedServicesAttribute to resolve a certain keyed service in the constructor:

public class MyClass
    public MyClass([FromKeyedServices("taxCalculator")] ITaxCalculator taxCalculator)
        TaxCalculator = taxCalculator;

Notice that the ExposeKeyedServiceAttribute only exposes the keyed services. So, you can not inject the ITaxCalculator or ICalculator interfaces in your application without using the FromKeyedServicesAttribute as shown in the example above.

If you want to learn more about the keyed dependency injection services, please refer to Microsoft's documentation and ABP Framework's Dependency Injection document.

Custom Menu Component Support for MVC UI

In this version, we have introduced the custom menu component support, which allows you to use a custom component for a certain menu item.

You can use the UseComponent extension method while defining menu items to use your custom component for the related menu item:

  new ApplicationMenuItem("Custom.1", "My Custom Menu", "#")

Then, for the related menu item, your custom component will be rendered on the UI.

Introducing the DisableAbpFeaturesAttribute

In this version, we have introduced the DisableAbpFeaturesAttribute to allow you to disable interceptors, middlewares, and MVC filters for a specific controller.

For example, you may want to disable interceptors for a certain controller, but you may also don't want to disable middlewares and mvc filters, in that case, you can use the DisableAbpFeaturesAttribute as follows:

[DisableAbpFeatures(DisableInterceptors = true, DisableMiddleware = false, DisableMvcFilters = false)]
public class MyController : AbpController


This can be useful if you have some APIs that are used frequently but you don't need all the features of ABP Framework.

Note: If you want to disable all interceptors, middlewares, and filters for a certain controller, then you can use the [DisableAbpFeatures] without the need to specify the parameters, they are disabled by default.

What's New with ABP Commercial 8.1?

We've also worked on ABP Commercial to align the features and changes made in the ABP Framework. The following sections introduce a few new features coming with ABP Commercial 8.1.

Suite: New Features

In this version, we mostly worked on ABP Suite and implemented some wanted features, such as bulk delete, filterable properties, customizable page title, allowing establishing relationships with installed ABP modules' entities and supporting the BasicAggregateRoot as the base class.

Bulk Delete

From this version on, ABP Suite allows you to perform bulk deletion of records based on specified criteria.


To enable bulk delete support, you should enable the Bulk delete option in the CRUD page generation page, along with the Create user interface option (they are enabled by default). When you enable the bulk delete support, you will see the checkboxes for each line in the datatable:


By selecting these checkboxes, you can delete all records in the current datatable (10 records by default), or delete all records in the database (by selecting select all xx items selection), or delete any records you want by selecting them one by one.

Note: This feature has already been implemented for MVC & Blazor UIs, but not implemented for Angular UI yet. We aim to implement it for Angular UI with v8.1.0-rc.2.

Filterable Properties

ABP Suite has been generating advanced filters for entities for a while and before this version, if you enabled the create user interface option, then all of the properties that you specified were included in the advanced filter section automatically.

In this version, we have introduced the filterable properties feature to allow you to select which properties should be filterable and which are not:


Now, you have full control to select which properties should be included as filter inputs and shown on the advanced filters section on your generated pages.

In other words, once, you select a property as not filterable, then the property will not be included in the filter inputs and in the advanced filter section. Also, if there are not any filterable properties for an entity, then the advanced filters section will not be generated.

Customizable Page Title

In this version on, ABP Suite allows you to specify the page title for the current entity.


You just need to specify the page title on the CRUD page generation page for a specific entity and then it will be used as a localization key in the application (and also will be localized - for example, if you specify it as 'MyPageTitle', then it will be localized in English as 'My Page Title'), so you can localize it for different languages later on.

Allowing Establishing Relationships with Installed ABP Modules' Entities

In this version, ABP Suite allows you to establish one-to-many relationship with pre-installed ABP Modules. You can add any entity from pre-installed ABP modules as a navigation property, by checking the Include entities from ABP modules checkbox in the navigation property model and choosing the related module entity as in the following figure:


In the example above, the IdentityUser entity is selected as the navigation property but you can also choose any entity from the installed ABP modules in the navigation property model.

Note: Ensure that your solution is built properly before establishing relationship between your own entity and a module entity because ABP Suite scans assemblies and finds which ABP modules you are using and lists their entities in the navigation property model if you have checked the Include entities from ABP modules checkbox.

Support BasicAggregateRoot Base Class

In this version on, ABP Suite allows you to choose the BasicAggregateRoot as the base class while generating an entity:


You can choose the BasicAggregateRoot if you want to create an aggregate root without the IHasExtraProperties and IHasConcurrencyStamp interfaces implemented (extra properties & concurrency check).

ABP Studio v0.6.5 Has Been Released!

We have just released v0.6.5 for ABP Studio and with this version, we fixed many minor bugs reported by you, started supporting running multiple ABP Studio instances, and added important features, such as adding a public website to the new microservice template, and so on...

In addition to all of this, we continue to enrich ABP Studio's documentation as always and you can read them at

Please try ABP Studio v0.6.5 and provide feedback to help us release more stable versions. Thanks in advance!
