I am using Castle Windsor v3.0.0.0 and am getting the following error when I
try to resolve a component from the container.
Castle.MicroKernel.ComponentActivator.NoResolvableConstructorFoundException
: Could not find resolvable constructor for EnvironmentValidationService.
Make sure all required dependencies are provided.
The registrations happen in an installer that we have written.
public void Install(IWindsorContainer container, IConfigurationStore store)
{
container.SafeFacilityInstall<TypedFactoryFacility>();
var validators = from a in AppDomain.CurrentDomain.GetAssemblies()
from t in a.GetTypes()
where
typeof(IEnvironmentValidation).IsAssignableFrom(t)
&& t.IsClass
&& !t.IsAbstract
select t;
foreach (var type in validators) {
_log.DebugFormat("EnvironmentValidationInstaller found and registered
'{0}'", type.Name);
container.Register(Component.For<IEnvironmentValidation>().ImplementedBy(type).LifeStyle.Singleton);
}
container.Register(Component.For<IEnvironmentValidationFactory>().AsFactory());
container.Register(Component.For<EnvironmentValidationExecutor>());
container.Register(Component.For<EnvironmentValidationService>());
var service = container.Resolve<EnvironmentValidationService>();
service.Start();
}
The code throwing the error is in the above installer
var service = container.Resolve<EnvironmentValidationService>();
The definition of those 3 types are as follows
public class EnvironmentValidationService : DelayableTimer, IDisposable
{
private static readonly TimeSpan seconds_30 = 30.Seconds();
private static readonly TimeSpan hour_1 = 1.Hours();
private EnvironmentValidationExecutor _executor;
public EnvironmentValidationService(EnvironmentValidationExecutor
exe, int minutesBetweenChecks)
: base(seconds_30, minutesBetweenChecks.Minutes())
{ ... }
public EnvironmentValidationService(EnvironmentValidationExecutor
exe)
: base(seconds_30, hour_1)
{ ... }
}
public class EnvironmentValidationExecutor
{
private IEnvironmentValidationFactory _factory;
public EnvironmentValidationExecutor(IEnvironmentValidationFactory
factory)
{ ... }
}
public interface IEnvironmentValidationFactory
{
IEnumerable<IEnvironmentValidation> GetValidators();
void Release(IEnvironmentValidation validation);
}
I'm not sure why I'm getting the errors. Since I can resolve the
EnvironmentValidationExecutor and the IEnvironmentValidationFactory, I would
assume that the container could resolve them in order to use the second
constructor on the EnvironmentValidationService. Any help would be
appreciated.
