Windsor Container: How to specify a public property should not be filled by the container?

Question

When Instantiating a class, Windsor by default treats all public properties of the class as optional dependencies and tries to satisfy them. In my case, this creates a rath

Posted this on the google groups forum too here: http://groups.google.com/group/castle-project-devel/browse_thread/thread/43aa513817bd057a

Answer 2

I created a facility to help with this:

• Castle.Facilities.OptionalPropertyInjection

Answer 3

I do not know which version of Castle you guys were using at that time, but none of the solution mentioned were working. Plus, there is a lot of dead links.

With castle 3.1, here the solution I came up with (thanks to some castle source code digging):

container.Register(Component.For(type)
                                        .LifestyleTransient()
                                        .Properties( propertyInfo => propertyInfo.PropertyType != typeof(MyOtherType)));

The 'Properties' function adds a property filter used by castle when constructing the ComponentModel. In my case, all properties dependency will be satisfied except the property type 'MyOtherType'.

This can be achieved by the following code:

var container = new WindsorContainer();

// We don't want to inject properties, only ctors
var propInjector = container.Kernel.ComponentModelBuilder
                         .Contributors
                         .OfType<PropertiesDependenciesModelInspector>()
                         .Single();
container.Kernel.ComponentModelBuilder.RemoveContributor(propInjector);

DoNotWireAttribute

• Class: http://svn.castleproject.org:8080/svn/castle/trunk/Core/Castle.Core/Attributes/DoNotWireAttribute.cs
• Test: http://svn.castleproject.org:8080/svn/castle/trunk/InversionOfControl/Castle.Windsor.Tests/IgnoreWireTestCase.cs

Answer 6

Maybe it will be helpful for someone. In Windsor 4.1 there is PropertiesIgnore method during registration.

Component.For<Role>().LifestyleTransient().PropertiesIgnore((model, propertyInfo) => true)
