MEF 和 MVVM - 添加约定的方法？
有没有办法连接到 CompositionContainer 的内部？
例如，假设任何时候在以“View”一词结尾的导出上调用导入时，我可能希望将以“ViewModel”结尾的导出注入到其 DataContext 中。
有办法做到这一点吗？我试图在每个视图中避免这样的代码：
[Export("MainView")]
public partial class MainView : Window
{
[ImportingConstructor]
public MainView([Import("MainViewModel")] dynamic viewModel)
{
InitializeComponent();
DataContext = viewModel;
}
}
最好简化为这样，并使用约定：
[Export("MainView")]
public partial class MainView : Window
{
public MainView()
{
InitializeComponent();
}
}
Is there a way to hook into the internals of CompositionContainer?
For example, let's say any time an import is called on a export ending with the word "View" I might want to inject an export ending with "ViewModel" into its DataContext.
Is there a way to do that? I'm trying to avoid code like this in every View:
[Export("MainView")]
public partial class MainView : Window
{
[ImportingConstructor]
public MainView([Import("MainViewModel")] dynamic viewModel)
{
InitializeComponent();
DataContext = viewModel;
}
}
Would be nice to simplify to just this, and use conventions:
[Export("MainView")]
public partial class MainView : Window
{
public MainView()
{
InitializeComponent();
}
}

有一些人正在研究这个问题，显然包括 Mef 团队:)

There are some folks working on this, including the Mef team apparently :)

我猜您正在寻找一个可以减少您工作量的库或框架。
请查看库WPF 应用程序框架。我用得很好。
I Guess you are looking for a library or framework which can reduce your effort.
Please have a look at library WPF Application framework. I am using it very well.
