In order to control the various RPAs created, I would like to be able to integrate RF into C# code.
Is this possible?
With python.NET is possibile integrate python on c# but when I run the .robot files the result is this:

[ ERROR ] Error in file 'D:\Development\Project\RPAManage\bin\Debug\net7.0-windows\python\robots\test.robot' on line 2: Importing library 'RPA.Windows' failed: OSError: [WinError -2147417850] Cannot change thread mode after setting it

Hi Salvatore,

This appears to be your problem:

It looks like one of the prerequisite python modules is missing, I’ve never used python.net so I don’t know what the equivalent to pip is or if that module is even available?

Hopefully that helps,

Dave.

The problem is not the comtypes library unfortunately. Is installed and work well without pythonnet library.

I think the problem is here:
[WinError -2147417850] Cannot change thread mode after setting it

but I can’t solve it.

I fix this problem with not use python.net but run process directly on c# wtih ProcessStartInfo class.
