我通过在XAML中设置以下窗口属性来创建无边框WPF窗口：
... WindowStyle="None" AllowsTransparency="True" ...
这会导致许多问题：
1）已解决：它不再具有任何内置调整大小功能
2）已解决：它不再具有任何内置拖动功能
3）已解决：如果没有顶部工具栏，则不再具有最小化/最大化/恢复/关闭按钮
4）已解决：通过aero快照最大化或设置WindowState可防止其被取消隐藏。
5）通过aero snap最大化或设置WindowState将使用整个屏幕作为边界，与窗口工具栏重叠。
6）通过aero快照最大化或设置WindowState似乎包含-7边距，使窗口每边超出窗口边缘7个像素。
通过制作xaml窗口模板来解决1-3的问题。我使用不可见的矩形作为句柄区域，后面的一些代码通过覆盖OnApplyTemplate（）来应用，通过user32.dll SendMessage（...）附加功能，用于resize / move / minimize / maximize / restore / close。我找到了＃4 here
的答案我尝试通过WndProc拦截最大化消息并手动设置大小/位置来解决5-6，但是这有一个问题，即将RestoreRegion覆盖到最大化的大小/位置，从而无法恢复窗口。
奇怪的是，将窗口从顶部边框调整到屏幕顶部会触发aero full height snap，没有任何问题。
所以，我已经走了很长的路，但5-6仍然是一个问题......有没有办法手动指定最大化区域？或者，有没有办法设置窗口大小而不影响restoreregion属性？

最简单的完整解决方案
您好，以下解决方案以最简单的方式修复了您的问题中详述的所有问题，并使用WPF和最新版本的C＃语言和.NET框架在Windows 10上运行。这是截至2017年3月15日。如果它停止工作，请告诉我。
第1步：要解决问题1,2和4，在应用程序的XAML中的<Window ... > </Window>标记内，将其粘贴到顶部或底部：
<WindowChrome.WindowChrome>
<WindowChrome CaptionHeight="35"/>
<WindowChrome.WindowChrome>
CaptionHeight是窗口拖动区域的所需高度。
第2步：要解决问题3，您需要创建标题栏和标题以及窗口控件。要做到这一点，你只需要给每个VerticalAlignment of Top提供所需的标题栏元素，或者将它们放入一个网格，其VerticalAlignment设置为Top，这将为所有这些做，但要确保它们的高度不是大于XAML中声明的CaptionHeight元素的WindowChrome属性，从步骤1开始。对于所有按钮，您必须为它们或其容器分配属性WindowChrome.IsHitTestVisibleInChrome="True"。这是一个例子：
<Grid VerticalAlignment="Top" Background="White" Name="TitleBar" Height="35">
<Label Content="Borderless Window Test" VerticalAlignment="Center" HorizontalAlignment="Left"/>
<StackPanel WindowChrome.IsHitTestVisibleInChrome="True" VerticalAlignment="Center" HorizontalAlignment="Right" Orientation="Horizontal" Name="WindowControls">
<Button Height="35" Width="35" Content="-" Padding="0" Name="MinimizeButton"/>
<Button Height="35" Width="35" Content="+" Padding="0" Name="MaximizeButton"/>
<Button Height="35" Width="35" Content="x" Padding="0" Name="CloseButton"/>
</StackPanel>
</Grid>
现在，要在窗口控件按钮中添加适当的功能，在代码隐藏的MainWindow()构造函数中，应用程序的C＃源代码，粘贴以下内容，在调用之后到InitializeComponent();：
CloseButton.Click += (s, e) => Close();
MaximizeButton.Click += (s, e) => WindowState = WindowState == WindowState.Normal ? WindowState.Maximized : WindowState.Normal;
MinimizeButton.Click += (s, e) => WindowState = WindowState.Minimized;
第3步：要解决问题5和6，您需要挂钩到WmGetMinMaxInfo。要执行此操作，请转到代码隐藏，然后将此Pastebin中的所有内容复制并粘贴到Window类中。现在，在MainWindow()构造函数中，粘贴：
SourceInitialized += (s, e) =>
{
IntPtr handle = (new WindowInteropHelper(this)).Handle;
HwndSource.FromHwnd(handle).AddHook(new HwndSourceHook(WindowProc));
};
通过文件菜单中的Project > Add References，请务必引用：
System.Management
System.Windows.Interop
System.Security.Principal
System.Runtime.InteropServices
Microsoft.Win32
最佳检查方法是点击左上角的Assemblies标签，然后选择Framework，然后使用窗口右上角的搜索框。现在将所有这些使用（名称空间）添加到代码隐藏的顶部：
using System.Management;
using System.Windows.Interop;
using System.Security.Principal;
using System.Runtime.InteropServices;
using Microsoft.Win32;
那应该涵盖一切。我希望这有帮助！
答案 1 :(得分：3)
对于第5点，请使用：
public WindowName() // Constructor for your window
{
this.MaxHeight = SystemParameters.WorkArea.Height;
this.MaxWidth = SystemParameters.WorkArea.Width;
}
这将确保窗口在最大化时不会与任务栏重叠。
答案 2 :(得分：2)
您可以通过处理WM_GETMINMAXINFO Win32消息来指定最大化区域。代码here显示了如何执行此操作。它将解决问题＃5和＃6。
请注意，我会做一些不同的事情，例如在WindowProc中返回IntPtr.Zero而不是（System.IntPtr）0并使MONITOR_DEFAULTTONEAREST成为常量。但这只是编码风格的变化，并不影响净结果。
另外，请务必注意在WindowProc事件期间SourceInitialized而不是OnApplyTemplate的{{1}}被更新的更新。那是更好的地方。如果您正在实现从Window派生的类，那么另一个选项是覆盖OnSourceInitialized以挂钩WindowProc而不是附加到事件。这就是我通常做的事情。

答案 4 :(得分：1)
我自己完成了这件事。这是一项真正的苦差事，因为你必须手动解释这么多。有趣的是，这些天我们非常理所当然地使用基本窗口如何操作这么简单。但是看看我提供的这个示例代码可以很好地说明这个问题到底有多少。
我希望这会有所帮助，因为我花了一点时间自己来这里。

答案 5 :(得分：0)
我知道这是一个较晚的答复，但是几年前我正在处理这些确切的问题，尤其是＃6。
对于＃6，如果将ResizeState设置为CanResize或CanResizeWithGrip，CanMinimize和NoResize全屏且没有过扫描，则将出现此问题。我要做的是创建具有最小化，最大化，关闭和DragMove（具有取消捕捉支持）功能的自己的标题栏，并创建了一个拇指作为调整大小的夹点以允许调整大小。
这仍然有一些缺点，例如只能从右下角调整大小并必须处理＃5。我还没有找到一种解决方案。
