Question 1

How to add logging interceptor with AspectCore?

Accepted Answer

Create a custom class implementing IInterceptor to wrap logging logic, then apply it via attributes or configuration in your DI container setup. The AspectCore.Extensions.DependencyInjection package simplifies registration for seamless integration.

Question 2

AspectCore vs PostSharp: which is better for AOP in .NET?

Accepted Answer

AspectCore is free and integrates well with .NET Core DI, but uses runtime proxies with performance overhead. PostSharp offers compile-time weaving for better performance but is a commercial tool with licensing costs. Choose based on budget and performance needs.

Question 3

Does AspectCore support async method interception?

Accepted Answer

Yes, AspectCore supports intercepting async methods by handling Task or ValueTask return types, allowing cross-cutting concerns like caching or validation in asynchronous code without blocking.

Question 4

How to integrate AspectCore with Autofac in ASP.NET Core?

Accepted Answer

Use the AspectCore.Extensions.Autofac NuGet package to replace Autofac's container with AspectCore's proxy-enabled version, enabling interceptors to be applied through standard Autofac registrations and attributes.

Question 5

What are the performance costs of using AspectCore in production?

Accepted Answer

Runtime dynamic proxy generation adds latency to method calls, which can impact high-performance scenarios. Benchmarking is recommended, as overhead varies based on interceptor complexity and invocation frequency.

Question 6

Can AspectCore be used for input validation in Web APIs?

Accepted Answer

Yes, via its built-in data validation features, you can create interceptors to validate parameters before method execution, though it may require additional setup compared to attribute-based validation in frameworks like ASP.NET Core.
