Question 1

How to integrate Castle Windsor with ASP.NET Core?

Accepted Answer

Use the Castle.Windsor.Extensions.DependencyInjection NuGet package to replace the built-in DI container. Configure it in Program.cs by setting up a service provider factory, which allows Windsor to manage dependencies in ASP.NET Core apps.

Question 2

Castle Windsor vs Autofac which is better?

Accepted Answer

Castle Windsor offers more advanced features like interception and is more mature, ideal for complex enterprise apps. Autofac is often faster and simpler for .NET Core projects, so choose based on your need for features versus performance.

Question 3

Does Castle Windsor support .NET 6?

Accepted Answer

Yes, through its .NET Standard 2.0 version, but with limitations: the conditional compilation table shows features like AppDomain and remoting are unavailable, so some legacy functionality is missing.

Question 4

How to use logging interceptors in Castle Windsor?

Accepted Answer

Create a class implementing IInterceptor to add logging logic, register it with the container using Component.For, and apply it to target components via attributes or configuration. This enables aspect-oriented logging without modifying business code.

Question 5

Is Castle Windsor still actively maintained?

Accepted Answer

Yes, as of 2023, there are recent releases and a CI feed for preview builds, but development pace is slower due to its maturity. Check the GitHub releases page for updates.

Question 6

What are the performance impacts of using Castle Windsor?

Accepted Answer

Windsor can have higher runtime overhead than lightweight containers, especially with complex dependency graphs and interceptors. Optimize by using transient lifestyles sparingly and caching components where possible.
