On Microsoft Windows NT 10.0.19045.0, I am reading OS info by
Environment.OSVersion
When I run app.exe by double click on it, OS Info is read Microsoft Windows NT 10.0.19045.0 but when I run code in visual studio 2022, OS Info is read Microsoft Windows NT 6.0.6002 Service Pack 2.
What setting should be done in visual studio for the correct OS read during my debugging? Please guide.

Target frameworkandPlatform targetof your project?The difference in the OS information you are observing between running the application as an executable and running it within Visual Studio can be attributed to the compatibility settings of Visual Studio. By default, Visual Studio runs applications in a compatibility mode to ensure backward compatibility with older versions of Windows. You could try the following steps.
- Right-click on your project in the Solution Explorer and select "Properties" from the context menu.
- In the project properties window, go to the "Debug" tab.
- Under the "Start Action" section, select the "Start external program" option.
- Click the "..." button next to the input field and browse to the location of your executable file.
- Click the "OK" button to save the changes.
By setting the "Start external program" option, you are specifying the executable file that Visual Studio should launch for debugging. This allows you to run your application as a standalone executable within Visual Studio, which should provide the correct OS information when accessing

@Hui Liu, Can you provide a reference to Microsoft documentation about the default use of compatibility shims by Visual Studio?
I know that Windows 10 will implement the "OS Version lie" as documented at GetVersion function if an application is not manifested as discussed in the documentation.
When I run a simple C# console app that prints the OS Version string the same results are returned under the VS Debugger and when running in a separately opened console. The Windows 8 version string is returned in both when the console app is not manifested and the Windows 10 version string is returned in both when it is.

@hui There are multiple projects in my solution.- Main startup project (Windows application)
Target framework=.Net6.0, Platform target=Any CPU
An Issue: I am trying to set it to x64, but it is immediately changed to Any CPU again.- Others 3 projects (class assembly)
Target framework=.Net6.0, Platform target=x64
- One project (class assembly)
Target framework=.NetFx 4.7.2, Platform target=x64.
There is no Start external program setting in VS-2022 in debug tab. Please guide if it has been moved anywhere
