I'm trying to use Emoji.Wpf ( https://github.com/samhocevar/emoji.wpf ) as shown in their examples but I keep hitting the error

The type or namespace 'Wpf' does not exist in the namespace 'Hamul.Emoji' (are you missing an assembly reference)?

when I use it like so:

...
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:emoji="clr-namespace:Emoji.Wpf;assembly=Emoji.Wpf"
...
.
.
.
<emoji:TextBlock x:Name="test" Text="test />

However, if I use just a regular TextBlock <TextBlock x:Name="test" Text="test" /> instead of emoji:TextBlock my project runs fine. It's a bit puzzling because I do have a xlmns:x entry and it works fine elsewhere except when trying to use it in any emoji components. Moreover, if I use my emoji component like so:

<emoji:TextBlock Text="test" />

It works fine as well so the issue seems to be just with using x:Name . Any help would be appreciated!

Answer 1

If you pay close attention to the error message The type or namespace 'Wpf' does not exist in the namespace 'Hamul.Emoji' (are you missing an assembly reference)? you may notice the Hamul .

If you have installed the most recent version 0.3.3 of the package you will notice that this namespace does not exist in the assembly. It's always Emoji.Wpf .

Please check your assembly references and make sure it points to the correct C:\Users\<user>\.nuget\packages\emoji.wpf\0.3.3\lib\netcoreapp3.1\Emoji.Wpf.dll or C:\Users\<user>\.nuget\packages\emoji.wpf\0.3.3\lib\net40\Emoji.Wpf.dll

Also debug this code

public partial class App : Application
{
    static App()
    {
        string assemblyLocation = Assembly.Load("Emoji.Wpf").Location;
    }
}

And make sure that the file at the specified location is exactly 622 KB (636.928 bytes) (net 4) or 622 KB (637.440 bytes) (net core)
