Ninject Interceptors - ninject

Question

I'm developing a WPF desktop application with caliburn.micro framework, and I want to configure ninject interceptors so that I can intercept method calls. I would like to do this to handle exceptions in a centralized place, so that I don't have many try-catch blocks everywhere around my code.
I haven't been able to acomplish this, because everytime I wire everything up with ninject, the system throws an exception.
So here's some code:
The AppBootstrapper configure method looks like this:
protected override void Configure()
{
_kernel = new StandardKernel(new NinjectServiceModule());
_kernel.Bind<IWindowManager>().To<WindowManager>().InSingletonScope();
_kernel.Bind<IEventAggregator>().To<EventAggregator>().InSingletonScope();
_kernel.Bind<ISomeViewModel>().To<SomeViewModel>().Intercept().With<SomeInterceptor>() //this is where the exception is thrown;
_kernel.Bind<IShell>().To<ShellViewModel>();
}
Now the intercept method in my interceptor:
public void Intercept(IInvocation invocation)
{
if (invocation.Request.Method.Name == "TheMethodIWantIntercepted")
{
try
{
invocation.Proceed();
}
catch (Exception)
{
Console.WriteLine("I Handled exception");
}
}
else
{
invocation.Proceed();
}
}
The method in the view model looks like this:
public virtual void TheMethodIWantIntercepted()
{
//Some logic here
}
So that's how interceptors are supposed to work. But it doesn't work, everytime I run the program, and ninject tries to inject the instance of SomeViewModel into ISomeViewModel, the program execution fails, and this is the exception that is thrown (and the stack trace):

Hope you can help me with this, thank you in advance.

Answer 1

You have to load either DynamicProxy(2)Module or LinFuModule depending on what proxy library you prefer.
Also be aware that Ninject 2.2 will create a class proxy for SomeViewModel which requires:
a parameterless constructor
virtual methods
Interface proxies don't have this restriction but this requires Ninject 3.0.0
