Thank you for your answer, I tried all of this without success. What do you mean by “select manually managed debugger”? Please can you clarify if it is possible to stop at breakpoints in C# code when called from Python code (using python dot net)?

The starting point is to ensure that you are on .NET 4+, select manually managed, native, and python debugger engines. Also make sure that managed compatibility mode is not selected. Finally make sure that your python debug symbols are available to PTVS/VS for cross-language debugging. Note that currently the PTVS remote debugger is not working for pythonnet when debugging python code.

From the Python code, I import and call functions from the C# class. When running in Debug, I am able to stop at breakpoints in the Python code, but not in the C# code. The debugger jumps over the calls as if no symbols were loaded. I would like to know if it is possible to stop at breakpoints in the C# code and how to setup it in Visual Studio. This feature works when using IronPython, but we want to use PythonDotNet from Miniconda3.
