Autofac: Is there a hidden debug feature?
I remember I have read somewhere here in SO (maybe I was dreaming) that I can enable a "hidden" debug feature of Autofac, so that it can give me more information on what Autofac is doing in the background.
I asked because I just encountered a bug in my project. After I have added the following code into my AutofacModule:
builder.RegisterAssemblyTypes(typeof(MainWindowViewModel).Assembly)
.AssignableTo(typeof(ViewModelBase))
.EnableClassInterceptors()
.InterceptedBy(typeof(NotifyPropertyChangedInterceptor));
when compile, at:
using (var container = builder.Build())
{
...
}
Autofac throws:
System.NotSupportedException was unhandled. Parent does not have a default constructor. The default constructor must be explicitly defined.
But it didn't tell me which class does not have a default constructor (maybe I have missed something in the outpu开发者_运维技巧t window?). I ended up opened all my ViewModel classes one by one... to check if they have a default constructor.
So it would be wonderful for me if Autofac has a hidden debug feature. If not, is there an automatic way to find all classes which don't have a default constructor?
Thanks
(sorry for my English)
this isn't an Autofac exception - it looks like it might be a WPF one? If you can get the call stack from the debugger when the exception is thrown it should offer a clue.
Cheers!
