The solution platform is essentially just a name, each individual project in it can have its own platform setting.

The Platform shows x64 but in Debug Properties the Platform shows "Any CPU".

In the codes it selects the following,

IntPtr.Size = 4

which means that it is Platform x86.

If it would be x64, then it should have selected

IntPtr.Size = 8

How can I get the program to force the change that it should be x64?

I suspect that's only happening when you debug - see my comment to your duplicate question.

Change your project's platform to be x64.

In your project's properties for AnyCPU uncheck the box for "Prefer 32-bit"

If you look at the image that I posted in the upper left corner there is a setting for configuration. That is where you can select the settings for either debug or release.
