RC1 with silverligth 5.0 issue.

[Marwijn]

Hello All,

Allthought silverlight 5.0 is nog formally supported I would expect
that binaries for SL 4.0 would work with silverlight 5.0. I experience
the error below upon the first resolve for the container.
Can this be related to http://issues.castleproject.org/issue/DYNPROXY-161,
which is marked as solved ?

Kind regards,

Marwijn.

There's also this issue report:

http://issues.castleproject.org/issue/DYNPROXY-163

I suppose there's a breaking change from SL4, which means that hack described in issue 161 no longer works. I'm pretty sure if you disable generation of strongly named module (there's a .ctor overload in ModuleScope) it will work.

Can you create a small reproduction of that issue I could use to investigate?

Krzysztof.

Hello Krzysztof,

To reproduce the problem in a simpler situation I've created a new
silver application project and put the code below in MainPage.cs and
added references to castle and windsor.
Reverting the project to Silverlight 4 did not solve the issue.
Allthough the application is then compiled for SL 4.0 I think is still
executed with the 5.0 runtime, which could cause the problem. This
could also mean that any application using castle and dynamicproxy
will fail when the user installs the new 5.0 runtime.
Sorry I've not seen issue 163 I think it is the same issue that I've
experienced.
I don't know how to use the .ctor overload, could you give me some
example code for that ?

Thanks for your time,

Marwijn.

public interface IA
{
void foo();
}
public class A : IA
{
public A()
{
}

public void foo()
{
}
}

public class MyInterceptor : IInterceptor
{
public void Intercept(IInvocation invocation)
{
invocation.Proceed();
}
}

public partial class MainPage : UserControl
{

public MainPage()
{
InitializeComponent();
IWindsorContainer container = new WindsorContainer();
container.Register(
Component.For<MyInterceptor>(),

Component.For<IA>().ImplementedBy<A>().Interceptors(InterceptorReference.ForType<MyInterceptor>()).Last);
var a = container.Resolve<IA>(); --> crashes cause proxy
cannot be created, without using an interceptor it will not crash.

}
}

Hello Krzysztof,

The suggestion with modulescope works. I'm using the code below now.
Thanks for the suggestion.

Marwijn.

private class MyProxyFactory : DefaultProxyFactory
{
public MyProxyFactory()
{
DefaultProxyBuilder proxyBuilder = new
DefaultProxyBuilder(new ModuleScope(false, true));
generator = new ProxyGenerator(proxyBuilder);
}
}

_container = new WindsorContainer(new MyProxyFactory());

I encountered a similar problem and send "push request" ( https://github.com/castleproject/Core/pull/4 ). If Krzysztof Koźmits approved fix, the problem will be solved

[Marwijn]

Thanks for solving k0st1x.
If there is a build available I can test if the changes work for me.

Kind regards,

Marwijn.
