How to call an ArcGIS Pro SDK (C#) Add-in project from Python ?

Question

Hi ! I created an Add-in project using the ArcGIS Pro SDK for .NET (C#) and now I'm trying to call the Add-in methods from my Python scripts using ArcPy but I didn't find neither documentation nor examples how to achieve this, I've tried some things however it didn't work and now I'm stuck... So I'm wondering if someone knows or has any ideas how to do this ?

Thank you.

We are now struggling with the same question and we would solve it the same way, as you did, Fabian.

I expected at least to be able to create a C#/.net-GP Tool to call it from python. I cannot understand, why this isn't supported in the Pro SDK.
Also nice would be to enable ArcGIS Pro command search and execution from python script.

It really does not make sense to call Python Script from C#/.net Code. Scripts are used to automate things, C#/.net to implement functions.

I picked this up to hopefully draw other customers and esri's attention to it.

Thanks for this post, Fabian and kind regards

Could the Python.NET module (pythonnet) be of any help?  (Old post, I know, but thought I'd mention it.)

Hi !

Currently there's no way to call an ArcGIS Pro SDK Add-In from a python script.

So, I implemented a workaround: I created a Console Application, which will be called from a python script, like an entry-point.

Note: This workaround only works if you're working with "ArcGIS.Core" and "ArcGIS.Corehost" assemblies, it crashes for all the other assemblies (ArcGIS.Desktop.*)

Cheers,
