Authoring GeoProcessing tool in .net

[BerndtNording]

Is there any documentation or samples that show how to create a Pro GP tool in .net. Documentation for Arcmap was rather spase and didn't cover .net, but there was a sample for a simple tool. I have not been able to find anything at all for Pro.

This has Pro and .net in it

Indeed, but nothing at all on authoring GP tools.

Hi @BerndtNording ,

Here is the pro sdk doco location for geoprocessing 

https://github.com/Esri/arcgis-pro-sdk/wiki/ProConcepts-Geoprocessing

And there are a few pro sdk community sample how to execute gptool from sdk .net.

If you want to create your own gptool, python toolbox, you need to create from ArcGIS pro first.

Here is the reference link.

And save your custom tool in a location, you can even call it from pro .net module.

Thank you for these links. So the short answer is that I cannot author GP Tools in .NET, and that any such tools have to be completely rewritten in Python.

I've been looking at all the developer guide/github websites and I too came to the conclusion that its not possible to create a geoprocessing tool in VB .net for ArcPro, unless I've completely missed the right search term?

I was hoping that this could be done and one builds up a toolbox of tools that a user could run individually or use to build a model in modelbuilder?

The approach of creating tools through python is not a solution for me as arcpy does not expose the fine grain manipulation that ArcObjects does. I wonder if any of the heavy weight developers who haunt this forum know better, or you really cannot create a geoprocessing tool for a toolbox using the ArcPro SDK?
