Description

Hi, dear guys,

I try to do this : _eventAggregator.GetEvent<AppConfigChangedEvent>().Publish(); But appConfigSource.GetConfig(); doesn't execute if my ViewModel like the following :

public MainWindowViewModel( IEventAggregator eventAggregator, AppConfigSource appConfigSource)
{
    _eventAggregator = eventAggregator;
    _appConfigSource = appConfigSource;
    _eventAggregator.GetEvent<AppConfigChangedEvent>().Subscribe(() =>
    {
           appConfigSource.GetConfig();
    });
}

modify little to like this, It can work.

public MainWindowViewModel( IEventAggregator eventAggregator, AppConfigSource appConfigSource)
{
    _eventAggregator = eventAggregator;
    _appConfigSource = appConfigSource;
    _eventAggregator.GetEvent<AppConfigChangedEvent>().Subscribe(() =>
    {
           _appConfigSource.GetConfig();
    });
}

Lambda Can't use method parameter appConfigSource, and have to use field _appConfigSource.
