I am writing a small app for as a school project and I cannot figure out how can I change the window icon. I found the "Icon" property of Window, but I have no clue how it works, as I have found little documentation on it. When I tried to input something in the field, it threw an error, that the resource could not be found. I read something on importing resources as well, but this is my first app of this kind, so I am completely lost. Any help much appreciated, thank you
You need to add your icon as AvaloniaResource. If you are using MVVM template, everything in Assets directory should be added as one. If you aren't, then add
<ItemGroup>
<AvaloniaResource Include="Assets\**" />
</ItemGroup>
to your .csproj file.
Then put your icon into Assets directory.
After that simply writing Icon="/Assets/your-icon.ico" in your window xaml should work.
