pythonnet: Calling generic method in Python returns incorrect value

Environment

• Pythonnet version: 2.3.0
• Python version: 3.6.0
• Operating System: Win10

Details

I’m trying to call a generic method from Python. So far it seems it’s executing but the result is not the same when calling it from C#.

So the actual method looks like:

public T GetService<T>() where T : class, IEngineeringService;

The method call in C# is:

SoftwareContainer softwareContainer = deviceItem.GetService<SoftwareContainer>();

And as expected it returns an object of type SoftwareContainer.

Calling it from python like:

software_container = device_item.GetService[SoftwareContainer]()

While it seems like the method is called as expected the returned value is None.

Note: I have an engineering project and I’m accessing it via a C# API. Both snippets act on the same project, so I guess the results should be the same for both cases.

Why does the Python code return an incorrect value?
