Wpf 结合MahApps.Metro和Caliburn.Micro

嗯，我尝试使用MahApps.Metro和Caliburn.Micro，但我遇到了一些问题

这是我的引导器

public sealed class TestBootstrapper : Bootstrapper<ShellViewModel> 
{
    private CompositionContainer container;

    protected override void Configure()
    {
        container = new CompositionContainer(new AggregateCatalog(AssemblySource.Instance.Select(x => new AssemblyCatalog(x)).OfType<ComposablePartCatalog>()));

        CompositionBatch batch = new CompositionBatch();

        batch.AddExportedValue<IWindowManager>(new AppWindowManager());
        batch.AddExportedValue<IEventAggregator>(new EventAggregator());
        batch.AddExportedValue(container);

        container.Compose(batch);
    }

    protected override object GetInstance(Type serviceType, string key)
    {
        string contract = string.IsNullOrEmpty(key) ? AttributedModelServices.GetContractName(serviceType) : key;
        var exports = container.GetExportedValues<object>(contract);

        if (exports.Count() > 0)
        {
            return exports.First();
        }

        return base.GetInstance(serviceType, key);
    }
}

这在某种程度上是可行的，但我的窗口周围有一个黑色边框，直到我重新调整大小时才看到下图

为什么会有黑色边框？我如何才能消除它（如果我手动调整窗口大小，边框就会消失。）？

似乎SizeToContent是问题所在

该问题的解决方案是将ResizeMode属性设置为“NoResize”，然后正确渲染边框

window = new MetroWindow()
{
    Content = view,
    SizeToContent = SizeToContent.WidthAndHeight,
    ResizeMode = ResizeMode.NoResize
};

---

对于Caliburn.Micro 2和Mahapps.Metro 1，上述内容不再是这两个框架的有效组合

在对卡利本的一些微文档和过时的指南进行挖掘之后，我得出了以下结论

首先创建引导程序，如下所示：

public class AppBootstrapper : BootstrapperBase
{
    private CompositionContainer container;

    public AppBootstrapper()
    {
        Initialize();
    }

    protected override void Configure() 
    {
        container = new CompositionContainer(
            new AggregateCatalog(
                AssemblySource.Instance.Select(
                x => new AssemblyCatalog(x)).OfType<ComposablePartCatalog>()
                )
            );

        CompositionBatch batch = new CompositionBatch();

        batch.AddExportedValue<IWindowManager>(new WindowManager());
        batch.AddExportedValue<IEventAggregator>(new EventAggregator());
        batch.AddExportedValue(container);

        container.Compose(batch);

    }

    protected override object GetInstance(Type service, string key) 
    {
        string contract = string.IsNullOrEmpty(key) ? AttributedModelServices.GetContractName(service) : key;
        var exports = container.GetExportedValues<object>(contract);

        if(exports.Any())
        {
            return exports.First();
        }

        throw new Exception(string.Format("Could not locate any instances of contract {0}.", contract));
    }

    protected override IEnumerable<object> GetAllInstances(Type service)
    {
        return container.GetExportedValues<object>(AttributedModelServices.GetContractName(service));
    }

    protected override void BuildUp(object instance) 
    {
        container.SatisfyImportsOnce(instance);
    }

    protected override void OnStartup(object sender, StartupEventArgs e) 
    {
        DisplayRootViewFor<IShell>();
    }
}

最后但并非最不重要的一点是，我们需要设置ShellView以使用MahApps.Metro窗口：

<Controls:MetroWindow x:Class="your-namespace.ShellView"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro">

    <Grid Background="White">
        <TextBlock Text="Hello Caliburn Micro!"
                   VerticalAlignment="Center"
                   HorizontalAlignment="Center"
                   FontSize="20" />
    </Grid>

</Controls:MetroWindow>

希望这能帮助其他希望在最新迭代中结合Caliburn.Micro和MahApps.Metro的人。

也许你应该将其标记为答案，如果相关的话，也许可以添加更多信息？对于那些感兴趣的人，似乎只需删除“SizeToContent=SizeToContent.WidthAndHeight”就可以解决问题谢谢你的发布，你上面的代码为我节省了不少时间！如果有人可以验证这是正确的解决方案，那么我会将其标记为答案！Phil，谢谢你发布这篇文章，这对我使用Caliburn和Mahapps Metro的最新版本很有效。你的文章似乎没有给出任何关于如何创建MetroWindow的新窗口的指示。Caliburn的默认WindowManager总是创建窗口，而不是MetroWindows。你有解决这个问题的办法吗？
