Visual Studio C++ Modules Intellisense

[01Pollux]

Xmake Version

xmake v2.9.3+HEAD.a5da06f37

Operating System Version and Architecture

Windows 11 23H2

Describe Bug

The code compiles correctly, but IntelliSense cannot detect the modules available in the current project.

Expected Behavior

As shown in the image, the expected behavior is that IntelliSense should be able to detect the modules linked against the current library. However, in reality, it does not.

After some investigation, I managed to resolve this issue by uncommenting the project references located in the .vcxproj file.

  <ItemGroup>
    <ProjectReference Include="..\mod\mod.vcxproj">
      <Project>{2B32DA8B-CA39-4549-A720-EAEACE53D244}</Project>
    </ProjectReference>
  </ItemGroup>

Project Configuration

add_rules("mode.release", "mode.debug")
set_languages("c++20")

target("mod")
    set_kind("static")
    add_files("src/mod.ixx", {public = true})
    add_files("src/mod.cpp")

target("hello")
    set_kind("binary")
    add_deps("mod")
    add_files("src/main.cpp")
