.NET DLL Loading from PML Macro in E3D Environment

I am using import statement to import .NET assembly from PML macro.

import 'TestApp.PMLVisible'

using namespace 'TestApp.PMLVisible'

!!SAGTestInterface = object TestInterface()

!!SAGTestInterface.Launch()

This approach requires DLLs to be co-located with the E3D installation, which restricts portability and centralized management of .NET dependencies. I have requirement to load .NET assemblies which are present in some network folder path.

What are the most robust methods for implementing custom assembly resolution in a PML context? How can we create a flexible, configurable mechanism for specifying DLL search paths?

I tried adding network folder in system PATH environment variable. But it did not work. Any suggestions?

Instead of simply specifying the DLL file name during import, you can use its absolute path.
For example, to import the DLL SampleAssembly.dll located under N:\AVEVA_Tools:
import 'N:\AVEVA_Tools\SampleAssembly'

Make sure not to include the .dll extension at the end, otherwise the path won't be recognized.

In a real scenario, the path would ideally come from an environment variable defined in your launchers.
With the previous example, suppose N:\AVEVA_Tools is stored in the environment variable AVEVA_TOOLS :
!dllPath = !!evar('AVEVA_TOOLS') & '\SampleAssembly' import '$!dllPath'
