MEF No exports were found that match the constraint
Hi, i'm trying to implement MEF in my WPF app, however i'm getting this error, not sure why anymore. Everything looks correct for me
This is my plugin:
and this is part of my WPF App.xaml.cs
is there something wrong?

Note that your two
IPlugin
interfaces are different types
So the one which your plugin claims that it implements is a different interface to the one which your WPF app is trying to find implementations ofR

looks like its the same when I leave IPlugin interface in wpf app, and add project reference to plugin to use same interface

So your plugin references your WPF app, but your WPF app is trying to load the plugin? That's a circular dependency
Normally you need to have another assembly, which contains the common types that both your app and your plugin rely on

I will stick to working samples like https://github.com/bezzad/MEF-Sample instead of rolling out my own.
