The tag 'Material' does not exist in XML namespace 'http://metro.mahapps.com/winfx/xaml/iconpacks'. #119

Closed allenlili closed 5 years ago

allenlili commented 5 years ago

In XAML,

<MenuItem Header="Save" Margin="5 0 0 0" Padding="0" Icon="{iconPacks:Material ContentSave, Height=12, Width=12}"/>

After building project, 'Error List' displays 'The tag 'Material' does not exist in XML namespace 'http://metro.mahapps.com/winfx/xaml/iconpacks'.

How to avoid this? Thanks.

Make sure to install the MahApps.Metro.IconPacks for your project.

To install the IconPacks, run the following commands in the NuGet Package Manager Console or install it with the NuGet Package Manager extension.

MahApps.Metro.IconPacks includes all Icons in one package on NuGet

PM> Install-Package MahApps.Metro.IconPacks

I opened an old project from summer last year and get the same error.

Der Name "PackIconMaterial" ist im Namespace "http://metro.mahapps.com/winfx/xaml/iconpacks" nicht vorhanden.

I'm getting this with PackIconMaterial or whatever else for Icons I want to use. IntelliSense is showing me the hints for the IconPacks, but as soon as I tap enter the code <iconPacks:PackIconMaterial ......." /> gets underlined and shows this error.

VS-version is: 15.9.2 Community 2017 --> also tested with 15.9.9 MahApps.Metro is 1.6.4 MahAps.Metro.IconPacks is 2.2.0 --> also tried to upgrade to current release 1.6.5 and 2.3.0 Building for AnyCPU and .NET 4.7.1

@allenlili @SAMUD Can you try to clean all bin and obj folders and build it again? Another tipp is to clean the Designer ShadowCache located in C:\Users\<USER>\AppData\Local\Microsoft\VisualStudio\14.0\Designer\ShadowCache (or whatever VS is installed)

@punker76 Sorry for not answering. I was busy.

I just had to reinstall my PC. So I'm starting of a clean install now. I cleaned all bin and obj folders, but didn't find the ShadowCache folder.

Errors are still the same: image

I attached some parts of the code:

<Controls:MetroWindow x:Class="TiaImporter.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:Dialog="clr-namespace:MahApps.Metro.Controls.Dialogs;assembly=MahApps.Metro" xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro" xmlns:iconPacks="http://metro.mahapps.com/winfx/xaml/iconpacks" mc:Ignorable="d" Title="TIA IMPORTER" Height="900" Width="1000" MinHeight="800" MinWidth="700" ResizeMode="CanResize" Icon="icon_nJ8_icon.ico" ShowIconOnTitleBar="True" Dialog:DialogParticipation.Register="{Binding}">

@SAMUD Here is my try with exact the same conditions like MahApps.Metro v1.6.5 and IconPacks v2.2.0. I used VS 2015 and all works fine => https://github.com/punker76/WpfAppMahAppsIconPacks
