Interface IQueryExpressionInterceptor

Namespace: Microsoft.EntityFrameworkCore.Diagnostics

Assembly: Microsoft.EntityFrameworkCore.dll

Allows interception of query expression trees and resulting compiled delegates.

public interface IQueryExpressionInterceptor : IInterceptor

Remarks

Use AddInterceptors(params IInterceptor[]) to register application interceptors.

Extensions can also register interceptors in the internal service provider. If both injected and application interceptors are found, then the injected interceptors are run in the order that they are resolved from the service provider, and then the application interceptors are run last.

See EF Core interceptors for more information and examples.
