community.windows.win_dotnet_ngen – Runs ngen to recompile DLLs after .NET updates

Note

This plugin is part of the community.windows collection (version 1.3.0).

To install it use: ansible-galaxy collection install community.windows.

To use it in a playbook, specify: community.windows.win_dotnet_ngen.

Synopsis

• After .NET framework is installed/updated, Windows will probably want to recompile things to optimise for the host.

• This happens via scheduled task, usually at some inopportune time.

• This module allows you to run this task on your own schedule, so you incur the CPU hit at some more convenient and controlled time.

Notes

Note

• There are in fact two scheduled tasks for ngen but they have no triggers so aren’t a problem.

• There’s no way to test if they’ve been completed.

• The stdout is quite likely to be several megabytes.
