Sorry @gaelcolas , but the build task keeps failing. I've added PlatyPS after the first failed build, now it fails with a different error. The change I did was just file path casing ;)

I will look into this. It should not run two of the tasks if PlatyPS is not available. I will let you know when you can revert the change to required modules.

[johlju]

Okay, a fix has now been released in DocGenerator so if PlatyPS is removed from the RequiredModules.ps1 this PR should pass build.

We have to wait for @gaelcolas to merge this as I don't have permission in this repo. 🙂

@gaelcolas, can we merge this AFTER having done a full release?
