Unlisted Windows dependencies

[Henri-J-Norden]

Description

EB CLI installation is broken on Windows since 3.23.0 - there are two issues:

1. The pythonnet package is not present in the built awsebcli.egg-info/requires.txt
   • This can be fixed by specifying the package in requirements.txt with an environment marker: pythonnet ; platform_system=="Windows"
2. It is assumed that IIS is installed on every Windows machine (also mentioned in 3.23.2 version errors due to missing Microsoft.Web.Administration.dll #551 (comment))

Steps to reproduce

1. Install awsebcli on a fresh install of Windows
2. Run any eb command

Observed result

$ uvx --from "awsebcli==3.23.0" eb --version

Expected result

This, but for newer awsebcli versions:

$ uvx --from "awsebcli<3.23.0" eb --version
EB CLI 3.22.1 (Python 3.13.2 (main, Feb 12 2025, 14:49:53) [MSC v.1942 64 bit (AMD64)])

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

1. OS: Windows 10.0.19045 Build 19045
2. EBCLI version: 3.25.0

Thanks for reporting this bug. pythonnet is not required to execute the EB CLI unless you need to execute eb migrate. We'll make the installation of pythonnet conditional.
