Hi, I have a problem , when i installed Visual Studio 2022 community i selected only this in installation detail C++ ATL and Windows 10 DSK (10.0.2348.0) and intellicode .

2025-01-23T14:21:08.79+00:00 You're welcome. The reason I suggested installing the complete workload was to ensure that you would be able to create and successfully build a C++ project. There could be optional components of the workload that you might not ultimately need but I didn't want to make assumptions or guesses about your intended usage of VS2022.
