Adding components does not solve the Error : Spectre-mitigated libraries are required for this project...

Question

After adding many components and setting the Spectre-Mitigation: Enabled (/Qspectre) still get the error:
"Error MSB8040 Spectre-mitigated libraries are required for this project. Install them from the Visual Studio installer (Individual components tab) for any toolsets and architectures being used. Learn more: https://aka.ms/Ofhn4c"

Hi @Cymon Kilmer -MSFT

Still get the error even after adding:

C++/CLI support for v142 build tools(14.28-16.8)
C++/CLI support for v142 build tools(Latest)
Visual Studio SDK
Windows 10 SDK(10.0.16299.0)
Windows 10 SDK(10.0.17134.0)
Windows 10 SDK(10.0.17763.0)

and removing unnecessary items:

MSVC v142 - VS 2019 C++ ....... (v14.26) (All the six)
MSVC v142 - VS 2019 C++ ....... (v14.27) (All the six)

Any idea?
thanks,
Ohad

@Ohad Leshets Firstly, I suggest that you reinstall Visual Studio and follow instructions from here - https://learn.microsoft.com/en-us/windows-hardware/drivers/download-the-wdk.

In summary, all you really need during VS installation is to select "Desktop development with C++" workload. Expand Desktop development with C++ and locate the MSVC v142 - VS 2019 C++ x64/x86 build tools (V14.xx) - note where xx should be the highest version available. With this information (v14.xx), go to Individual components and search for v14.xx. This will return the tool sets for all architectures, including Spectre mitigated libs. Select the driver architecture you are developing for. For example, searching for v14.25 returns the following:

MSVC v142 - VS 2019 C++ ARM build tools (v14.25)
MSVC v142 - VS 2019 C++ ARM Spectre-mitigated libs (v14.25)
MSVC v142 - VS 2019 C++ ARM64 build tools (v14.25)
MSVC v142 - VS 2019 C++ ARM64 Spectre-mitigated libs (v14.25)
MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.25)
MSVC v142 - VS 2019 C++ x64/x86 Spectre-mitigated libs (v14.25)
