Visual Studio folding solution items recursively - visual-studio

Question

I am trying to fold all XAML dependents files.
<None Include=".\**\*.xaml.js">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<DependentUpon>.\%(RecursiveDir)%(FileName)</DependentUpon>
</None>
<None Include=".\**\*.xaml.d.ts">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<DependentUpon>.\%(RecursiveDir)%(FileName)</DependentUpon>
</None>
I was able to fold JSs but TS definitions fail
I tried to create a "temp" items collection and tried to iterate and parse paths ... no success VS didn't load the project anymore
<ToFold Include=".\**\*.xaml" />
<None Include="#(ToFold->%(RecursiveDir)%(FileName).js')" DependentUpon="#(ToFold)">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
I tried the same way in "another way" ... same way :(
<ToFold Include=".\**\*.xaml" />
<None Include="#(ToFold->%(ToFold).js')" DependentUpon="#(ToFold)">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
</None>
Question
Is it possible to parse path in another way than x->%(RecursiveDir)%(FileName ?
Is it possible to fold items like *.dash.ext ? How ?
Or someone could help me achieving this ?!
NOTE
xaml.ts are auto generated and somehow auto folded

Answer 1

I think the issue is that:
For KYCHome.xaml.d.ts file, the value of %(FileName) is KYCHome.xaml.d rather than KYCHome.xaml. So when you use it, it will not find the KYCHome.xaml file.
So the method I can think of is to intercept the FileName, remove the .d, and then the changed value is what we need.
Solution
This is what I used:
<ItemGroup>
<None Include=".\**\*.xaml.js">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<DependentUpon>%(RecursiveDir)%(FileName)</DependentUpon>
</None>
<None Include=".\**\*.xaml.d.ts">
<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
<File>$([System.String]::Copy('%(Filename)').Replace('.d', ''))</File>
<DependentUpon>%(RecursiveDir)%(File)</DependentUpon>
</None>
</ItemGroup>
Note: you should remove the .\ under DependentUpon node. Otherwise, sometimes, the DependentUpon will not work when you restart your project or unload the project.

I'm first French and I think it was a barrier for me to achieve what I wanted to do. I was saying folding items but if instead I had said nesting items I would quickly get my answer from google.
Visual Studio has a nesting items feature
I got the answer from here Path segment pattern and here is the node I added in the .filenesting.json solution file
"dependentFileProviders": {
"add": {
"addedExtension": {},
"pathSegment": {},
"fileSuffixToExtension": {
"add": {
".xaml.d.ts": [".xaml"]
}
}
}
}
