RimWorld Harmony Library Mod

This mod brings the Harmony library into RimWorld modding.

GitHub Repository: Harmony

Instead of including 0Harmony.dll in your Assemblies folder, you use the Harmony reference from nuget: Lib.Harmony.Ref. Then, you add the following to your About.xml file:

<modDependencies>
    <li>
        <packageId>brrainz.harmony</packageId>
        <displayName>Harmony</displayName>
        <steamWorkshopUrl>steam://url/CommunityFilePage/2009463077</steamWorkshopUrl>
        <downloadUrl>https://github.com/pardeike/HarmonyRimWorld/releases/latest</downloadUrl>
    </li>
</modDependencies>

which will make RimWorld force the user to install this mod. It will automatically want to be installed high up in the list which makes it supply HarmonyLib to all mods below. This means that all mods will use the same Harmony version.

Whenever Harmony needs updating, this mod will update too.

Notes

Adding HARMONY_NO_LOG (any non-empty value will do) to your environment variables will suppress the creation of the harmony.log.txt file that is created if some mod author forgets to remove debugging before releasing their mod. See also How to edit environment variables.

If you want to turn off the enhancement of stacktraces, you can edit the tweak values of RimWorld (use Debug mode, then the second debug icon from the left) and check the following tweak variables:
