Double is not supported in a Windows Present

26 Aug 2019, 09:21

I'm trying to specify height as a resource in xaml.
What I found in other forums was this:
   
   <Window x:Class="MyName.WindowMobile"
        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:MyName"
        mc:Ignorable="d"
        Title="WindowMobile" Height="640" Width="320" Background="#FFF0F0F0">
   
   
    <Window.Resources>
        <sys:Double x:Key="Height">200</sys:Double>
        <sys:Double x:Key="Width">200</sys:Double>
    </Window.Resources>
However, I get this error
XDG0008 Double is not supported in a Windows Presentation Foundation (WPF) project.
XDG0008 Double is not supported in a Windows Presentation Foundation (WPF) project.
XDG0006 The namespace prefix "sys" is not defined.
XLS0414 The type 'sys:Double' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.
Is this method outdated?

You are missing the System namespace definition where Double type is declared:
xmlns:sys="clr-namespace:System;assembly=mscorlib"
