Symptoms

Normally I'd just play the native linux version, but the new DLC doesn't have a linux version. Discovered that the game crashes on startup with the following error:

The entry point method could not be loaded due to Could not load file or assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

Looks like some .net thing is missing.

Reproduction

Enable steam play via the game properties dialog. Start game.

Start by reproducing Borderlands 2 with Steam Play and Proton 4.2-6, then inspect the attached steam-49520.log for the PresentationFramework loading failure. Compare the startup behavior and log with the reported system information and available Proton compatibility work. Done means the game starts successfully or the compatibility limitation is clearly confirmed and documented.
