Fast Up-To-Date Check: Build-time generated <Content/> files not copied

Visual Studio Version

Microsoft Visual Studio Professional 2022 (64-bit) - Current
Version 17.10.4

Summary

I have a dependency (Class library) which generates some content files in the build-time. And this files are not copied into the app output directory when FUTDC are used.

Steps to Reproduce

1. Download solution: Test.zip
2. Make full rebuild
3. Check the App\bin\Debug\net8.0\ContentDir folder and make sure that both static and dyncmic content files are here: StaticContent.xml & DynamicContent.txt
4. Remove the App\bin\Debug\net8.0\ContentDir folder.
5. Hit F5 in VS to make a build with a FUTDC
6. Check the App\bin\Debug\net8.0\ContentDir folder content

Expected Behavior

both static and dyncmic content files were copied during the build: StaticContent.xml & DynamicContent.txt

Actual Behavior

Only static content was copied, the folder contains only the StaticContent.xml file. DynamicContent.txt is missing.

User Impact

FUTDC gives the unpredictable build resultd depending on the state of the output folder, so I was forced to disable FUTDC globally.

Additional details

• The build-time Content files generation was made based on the following manual: https://learn.microsoft.com/en-us/visualstudio/msbuild/customize-builds-for-generated-files?view=vs-2022
• The custom target is in the ClassLib\ClassLib.csproj file
• I have also tried to hook up dependencies for the additional targets without success.

<AssignTargetPathsDependsOn>$(AssignTargetPathsDependsOn);MyTarget;</AssignTargetPathsDependsOn>
<GetCopyToOutputDirectoryItemsDependsOn>$(GetCopyToOutputDirectoryItemsDependsOn);MyTarget;</GetCopyToOutputDirectoryItemsDependsOn>

• I suspect then this issue may be caused by the same thing as Fast Up-To-Date Check: Project considered up-to-date even its dependency was considered outdated and was rebuilt #9350, but can't say for sure.
