I have added code block formatting. For some reason using HTML / XML formatting does not work. So I have choosen plain text which looks at least better than the original post.

1 solution

If that is exact XAML (note that it is XAML not XML) then Visual Studio would not load it. Error message may be, "Invalid Markup".

Window is the actual control, not window. The markup is case-sensitive (unlike HTML).

XML
<Window x:Class="SelectionMaker.Window1">
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:cv="clr-namespace:SelectionMaker"
    xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
    Title="Selection Maker" Height="600" Width="800" 
    WindowStartupLocation="CenterScreen"  
    Loaded="Window_Loaded" Removed="LightGray" Closing="Window_Closing" 
    Activated="Window_Activated">
</window>


What is that Removed attribute? Maybe that would also cause a trouble with this valid markup. You may want to learn Windows Presentation Foundation[^] from beginning.

Is it not like this that xml defines the syntax and xaml uses the syntax and adds some grammar? Just a question from a beginner.
Afzaal Ahmad Zeeshan 9-Aug-15 9:36am    
Indeed, XML is the base of XAML. But, XAML has some of its own characteristics. XML is a base for HTML too, which is case-insensitive. However XAML on other hand is case-sensitive. That is the problem.

Wow, thank you very much for this Information. But XML itself is also case-sensitive or am I wrong?
[Edit]
Just recognized, I mixed up the things. Sorry.

No worries. Everyone makes mistakes, glad you made it to the right side. :-)
