What references are required (in your project) to build a 64 bit Visual Studio application?

What references are required (in your project) to build a 64 bit Visual Studio C# application?

I am using DAQmx version 18.6 (for PCIe 6323)

After the install, I do not see files that look like they could be appropriate references in the project, nor have I been able to find example programs or documentation for building a 64 bit C# application.
