Image with Problem
This is a WPF application launched with debug of visual studio
I've a window, where show content
<Window x:Class="Test.All"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:Test"
mc:Ignorable="d"
Title="All" Height="450" Width="800">
<Grid>
</Grid>
and a user control, with the content to show in the window
<UserControl x:Class="Test.ShowContent"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:local="clr-namespace:Test"
mc:Ignorable="d"
d:DesignHeight="450" d:DesignWidth="800">
<Grid>
<Button x:Name="btnrand" Content="button" HorizontalAlignment="Left" Margin="300,69,0,0" VerticalAlignment="Top" Width="200" RenderTransformOrigin="0.473,0.477" Height="58" Click="btnrand_Click"/>
<Label x:Name="showblasph" Content="" HorizontalAlignment="Left" Margin="60,169,0,0" VerticalAlignment="Top" Height="163" Width="664" FontSize="24"/>
</Grid>
</UserControl>
With a WinForms application, I did not have that problem, but with wpf yes, any ideas?
The problem is the arrows at the top

You are accidentially using a NavigationWindow instead of a Window. A navigation window has built-in browser-like controls. These controls are not shown in the Visual Studio designer, but at runtime. The black bar at the top are the XAML debugging tools, that you can enable or disable in debug mode.
A navigation window is used automatically, if you specify a UserControl resource as StartupUri. What type of window is used or created depending on the startup URI is documented here.
Types that display a NavigationWindow when set as StartupUri resource:
NavigationWindow
Page
UserControl
FlowDocument
PageFunction<T>
Therefore, you have to set a Window as StartupUri and set its Content to your UserControl.

Visual C# 2013 - Element disappearing when adding a new one in WPF form editor

When I try adding more than one element to my WPF form in the editor in VC#2013, the previous element disappears. In the end, I can't have more than one item in the form. I've already written some code so I'd prefer not starting again from scratch. The form has nothing special besides being borderless, fullscreen and starting maximized.
This is the XAML code for the form right now:
<Window x:Class="queue_bigscreen.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="1080" Width="1920" WindowStyle="None" ResizeMode="NoResize" WindowState="Maximized" Background="#FF9EA7CD">
<Label x:Name="nowServingLabel" Content="0" Margin="42,56,1160,131" Foreground="White" Height="893" FontSize="700" HorizontalContentAlignment="Center">
<Label.Effect>
<DropShadowEffect ShadowDepth="13"/>
</Label.Effect>
</Label>
</Window>
And this is what I get after I select a textbox and try adding it to the form:
<Window x:Class="queue_bigscreen.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="1080" Width="1920" WindowStyle="None" ResizeMode="NoResize" WindowState="Maximized" Background="#FF9EA7CD">
<TextBlock HorizontalAlignment="Left" Margin="1332,382,0,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/>
As you can see, the label disappears, and the textbox I added in turn disappears if I try adding something else. Am I doing something wrong or is it a known bug?

You need to put the items in a container. Window can only have a single root element, so to get multiple elements on the form, you need to have an element that allows children.
The closest to Windows Forms Form would be Grid. You can then put controls in that, with absolute and relative positioning. It's also the default, so I assume you accidentally deleted it from your XAML (or by being too aggressive with pressing delete in the designer).
Example form with a label and a textbox:
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Label Content="Label" HorizontalAlignment="Left" Margin="23,30,0,0" VerticalAlignment="Top"/>
<TextBox HorizontalAlignment="Left" Height="23" Margin="66,32,0,0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Top" Width="120"/>
</Grid>
</Window>

UI Elements placed in the wrong place while running in full screen

I am having a C# WPF application that runs in full screen. When I place a button in the top right of the canvas and run the application the button doesn't appear. What i figured it out is that the canvas is larger than the screen although I made it the same width and height as the screen resolutions.
PS: The application is working fine on another computer and the canvas size is correct but when I run it on my laptop or PC the same problem appears.
<Window x:Name="Mywindow" x:Class="Graduation_Project.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" SizeToContent="WidthAndHeight" Height="768" Width="1366" WindowStyle="None"
ResizeMode="NoResize" WindowStartupLocation="CenterScreen"
WindowState="Maximized" Topmost="True" HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
<Canvas Name="workspace">
<Label x:Name="Print" Content="Label" Canvas.Left="57" Canvas.Top="719" Width="74"/>
</Canvas>
</Window>

Remove the Height="768" and Width="1366" properties from the Window.

WPF window gets minimized instantly

SOLUTION here
I was asked to emulate a windows forms context menu using a WPF window. I created a window when the user clicked a certain region, but that window got minimized to the task bar instantly. I need it to stay on top of other windows at least until it loses focus or is deactivated. Its window style is none, and it doesn't matter whether its show in taskbar property is true or false. Similar questions exist on SO, but they don't seem to solve anything in my case. Why this odd behavior? Is there a fix for it?
<Window x:Class="InterceptRouteWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" Width="200" ResizeMode="NoResize" SizeToContent="Height" ShowInTaskbar="False" Loaded="Window_Loaded" WindowStyle="None" Height="auto" Deactivated="Window_Deactivated">
<StackPanel Height="auto" Name="stackPanel1" Width="200" Background="WhiteSmoke">
<Separator Height="5" FlowDirection="LeftToRight">
<Separator.Background>
<SolidColorBrush />
</Separator.Background>
</Separator>
</StackPanel>
</Window>
So it's a simple window. The way I invoke it:
IRWindow = gcnew InterceptRouteWindow(routes, fpId, offsetPoint.x, offsetPoint.y);
GetMainFrame()->IRWindow->Show();
This is triggered by a click event inside an older app, a mixture of MFC and WindowsForms.. not my code, I had to obey their design and use WPF where I could.

Wpf button text in Expression Blend

Normally, If i use the button in C# Windows form, and if the button text is too long, it will go to next line. (Eg. Very Happy, Happy will go to next line). But When i use wpf app in expression blend, the text will be truncated even though i set the auto size to false. (Eg. Very Happy, Happy will be truncated). Any advice would be really appreciated. Thank you.

You need to place a TextBlock inside your button and set the TextWrapping attribute to Wrap.
Example:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WpfApplication1.MainWindow"
x:Name="Window"
Title="MainWindow"
Width="640" Height="480">
<Grid x:Name="LayoutRoot">
<Button HorizontalAlignment="Left" VerticalAlignment="Top" Width="40" Height="40">
<TextBlock Text="Very Happy" TextWrapping="Wrap" />
</Button>
</Grid>
</Window>
