Type: LanguageService

Describe the bug

  • OS and Version: Windows 10 Build 19041.508
  • VS Code Version: 1.49.1
  • C/C++ Extension Version: v1.0.0
  • Other extensions you installed (and if the issue persists after disabling them): CMake Tools, CMake, indent-rainbow, Output Colorizer, Bracket Pair Colorizer 2
  • Does this issue involve using SSH remote to run the extension on a remote machine?: No
  • A clear and concise description of what the bug is, including information about the workspace (i.e. is the workspace a single project or multiple projects, size of the project, etc).
    The workspace contains a main.cpp

Steps to reproduce

  1. Go to the command palette and type C/C++: Edit Configurations (UI)
  2. Set the C++ standard to c++20
  3. Create a new file named main.cpp
  4. Paste the following code:
#include <ranges>

int main()
{
    std::
}
  1. Put the cursor after std:: and hit Ctrl+Space
  2. There is only align_val_t and nullptr_t in the intellisense suggestion where there should be an extra ranges namespace being shown

Expected behavior

ranges namespace should be shown in the intellisense suggestion
