+## Use NoTracking for readonly repositories for EF core. 
+
+In this version, ABP Framework provides read-only [repository](Repositories.md) interfaces (`IReadOnlyRepository<...>` or `IReadOnlyBasicRepository<...>`) to explicitly indicate that your purpose is to query data, but not change it. If so, you can inject these interfaces into your services.
+
+Entity Framework Core read-only repository implementation uses [EF Core's No-Tracking feature](https://learn.microsoft.com/en-us/ef/core/querying/tracking#no-tracking-queries). That means the entities returned from the repository will not be tracked by the EF Core [change tracker](https://learn.microsoft.com/en-us/ef/core/change-tracking/), because it is expected that you won't update entities queried from a read-only repository.
+
+> This behavior works only if the repository object is injected with one of the read-only repository interfaces (`IReadOnlyRepository<...>` or `IReadOnlyBasicRepository<...>`). It won't work if you have injected a standard repository (e.g. `IRepository<...>`) then casted it to a read-only repository interface.
