IntelliSense Support for Resources from winui Custom Control Library in nuget

Mahdi Hosseini 270

I was able to make it work by using a hardcoded string:

 <None Include="Themes\Generic.xaml" Pack="true" PackagePath="lib\net8.0-windows10.0.19041\DevWinUI.Controls\Themes\" />

However, since I’m using multiple target frameworks, I need to make it dynamic. So I used:

<None Include="Themes\Generic.xaml" Pack="true" PackagePath="lib\$(targetframework)\DevWinUI.Controls\Themes\" />

However, as you can see, this approach does not work and results in an “Unrecognized framework” error. The DevWinUI.Controls folder and its subfolders/items should be placed inside net10.0-windows10.0.19041, net8.0-…, and net9.0-….

How can I make this work?

To reproduce the issue, you can create a blank class library, configure it to target multiple frameworks, add an empty resource dictionary at Themes\Generic.xaml, and then enable Generate package on build.

<GeneratePackageOnBuild>true</GeneratePackageOnBuild>

Hello @Mahdi Hosseini ,

You could try to update your code to:

<None Include="Themes\Generic.xaml" Pack="true" PackagePath="lib\$(TargetFramework)\DevWinUI.Controls\Themes\" />

If the fix above doesn't work, you can use the TargetsForTfmSpecificContentInPackage approach:

<PropertyGroup>
  <TargetsForTfmSpecificContentInPackage>$(TargetsForTfmSpecificContentInPackage);PackCustomContent</TargetsForTfmSpecificContentInPackage>
</PropertyGroup>

<Target Name="PackCustomContent">
  <ItemGroup>
    <TfmSpecificPackageFile Include="Themes\Generic.xaml">
      <PackagePath>lib\$(TargetFramework)\DevWinUI.Controls\Themes\</PackagePath>
    </TfmSpecificPackageFile>
  </ItemGroup>
</Target>

I hope this helps, and happy holidays.

Thank you so much, second approach worked, however it adds folders with .0:

i removed .0 from folders:

<PropertyGroup>  <CleanTargetFramework>$([System.Text.RegularExpressions.Regex]::Replace('$(TargetFramework)','\.0$',''))</CleanTargetFramework> </PropertyGroup>

and this is result:

is it now Ok? can i use it in my project?

Thank you again

It should be fine. But you should test your package in a consuming project to make sure it is working.
