调研方向

Reproduce the failure with the linked example, focusing on ProjectA's libman.json, ProjectA.csproj, and ProjectB's RunLBeforeBuildStepgen target. Inspect the LibraryManager build integration around LibraryManagerRestore and compare its ordering with referenced-project targets. Done means the generated Localizations.js is available before filesystem provider resolution without manually building ProjectB.

描述

Problem
ProjectB generates files in a Target

<Target Name="RunLBeforeBuildStepgen" BeforeTargets="BeforeBuild" >
	<Message Text="=== Generating localizations ===" Importance="high" />
       <WriteLinesToFile File="Localizations.js" Lines="Localization data generated before build." />
</Target>

ProjectA have this in its libman.json

{
  "version": "1.0",
  "defaultProvider": "filesystem",
  "libraries": [
    {
      "library": "../../ProjectB/",
        "files": [ "Localizations.js" ],
      "destination": "wwwroot/assets/l10n/"
    }
  ]
}

dotnet build .\ProjectA\ProjectA\ProjectA.csproj fails:

https://github.com/aspnet/LibraryManager/issues/642 describes a similar problem. But in my case its a target in a referenced project. And yes, also tried BeforeTargets="LibraryManagerRestore"

Created a little repo https://github.com/AlexanderRydberg/LibraryManagerTargetIssue

Expected behavior
Targets in referenced project being run before libman.

Is this behavior by design?
Any suggestions on how I could solve this without:
manually building ProjectB first and then ProjectA
or
Copy Target from ProjectB to ProjectA's csproj and have BeforeTargets="LibraryManagerRestore"
