Incomplete winget command for MSVC install on Windows 10

[Adrilihan]

Environment

• OS and Version: Windows_NT x64 10.0.19045
• VS Code Version: 1.97.2
• C/C++ Extension Version: 1.23.6

Bug Summary and Steps to Reproduce

Bug Summary:

The winget command given on the walkthrough winget install Microsoft.VisualStudio.2022.BuildTools --force --override "--wait --passive --add Microsoft.VisualStudio.Workload.VCTools --add Microsoft.VisualStudio.Component.VC.Tools.x86.x64 --add Microsoft.VisualStudio.Component.Windows10SDK" installs an incomplete MSVC compiler that is unable to run the hello world example given on the walkthrough.

Steps to reproduce:

1. Go to C++ walkthrough "Get Started with C++ Development"
2. Execute the winget command given to install the Microsoft Visual C++ (MSVC) compiler
3. Create the C++ file just like shown in the picture of step 2 of the walkthrough (the code is in the additional context section of this issue)
4. See error about missing float.h from the #include <iostream>

Expected behavior:

Correct and complete installation of the MSCV compiler, which can execute the provided hello word example.

Temporary fix:

1. Reinitialize the Visual Studio Installer
2. Modify the installation of Visual Studio Build Tools 2022
3. Deselect and select again the Desktop development with C++. There should be an additional 3GB of files to be installed
4. Install

Basically, follow the instructions present in https://code.visualstudio.com/docs/cpp/config-msvc

No response

Additional context

Code in question of hello-world.cpp:

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Returns

C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\VC\Tools\MSVC\14.43.34808\include\cfloat(10): fatal error C1083: Cannot open include file: 'float.h': No such file or directory

When compiled with MSVC compiler.

PS: On step 3 of the walkthrough "Launch from the Developer Command Prompt for VS" displays a blue button that restarts the VSC window, yet the instructions require that you close VSC and start it from development cmd or pwsh.

Thank you for reporting this. I could have sworn that was the command I tested on Windows 10 back when we added this feature in, but based on this page it would seem the correct package is now Microsoft.VisualStudio.Component.Windows10SDK.20348. I'll submit a fix and update the Windows 11 package while I'm at it.

Yeah, we should remove that. I'm actually working on a solution to make this scenario work without requiring you to launch from a Developer Command prompt in the future. Follow this issue to track when it's complete: #5271
