When you migrate .NET code modules from 32-bit TestStand to 64-bit TestStand, NI recommends using platform-independent AnyCPU assemblies in shared locations. Use one of the following techniques to migrate platform-specific assemblies:

  • Use the $(Platform) path macro.
  • Place the assembly in a non-shared search directory.
Note If you are using TestStand 2023 Q4 or earlier, you can also register the assembly in the GAC or use .NET remoting to call a non-matching bitness version of the DLL to migrate platform-specific assemblies.
