Usage with MVVM and WPF

[Brian]

Hey there,

I read through the wiki and have tried to find examples of how to use
Ninject in a WPF application and haven't had much luck. I'm using
Ninject with MVC3 and it works great! I wire up the MVC Start and
declare my bindings and everything magically works.

Where I'm having confusion is how do I use Ninject in a WPF
application that implements the MVVM pattern. Basically what I can't
figure out is where I do set up my bindings?

Thanks

Hi Brian

Have a look at MPF frameworks like Caliburn micro. They usually provide support for IoC containers.

Sry I mean WPF frameworks

1. If you are not using any MVVM framework here are some simple steps...

a. Create a class called ServiceLocator, like so...

public class ServiceLocator
{
private static IKernel kernel_;

static ServiceLocator()
{
kernel_ = new StandardKernel(< your module>)
}
}

b. Then in App.xaml, create a resource called ServiceLocator

<xxxx:ServiceLocator x:Key="ServiceLocator"
d:IsDataSource="True" />

c. Then wire up the correct view model in your XAML like so:

DataContext="{Binding YourViewModel, Source={StaticResource
ServiceLocator}}", where "YourViewModel" is a static property on the
ServiceLocator class.

2. If you are using MvvMLight, you can replace the service locator with your
own implementation as described above.

3. Caliburn.Micro has facilities for plugging in any IoC you like.

HTH,

BTW, I misspoke in 1.c. The property need not be a static property.

AWESOME! Thanks so much! We are not using an MVVM framework such as
Caliburn. We are using a homegrown simplified version and these
responses were exactly what I was needing!

Thanks!
