Unity Recorder won't install

I have Cinemachine v 2.2.9 installed in Unity 2018.3.11.f1, but no Unity Recorder. When I tried to install Recorder version 2.2.0, I got this error message:
2018/Library/PackageCache/com.unity.recorder@2.2.0-preview.4/Editor/Sources/Recorders/_Inputs/Camera360/Camera360InputSettings.cs(25,17): error CS1644: Feature `expression bodied members’ cannot be used because it is not part of the C# 4.0 language specification

Help would be appreciated!

Hey @dsantamonica ! Based on the error, it looks like your project is using an older version of .NET that is unfortunately not compatible with the Recorder package.

You can validate this by going to Edit -> Project Settings -> Player -> Other Settings -> Scripting Runtime Version. It needs to be .NET 4.x Equivalent for the Recorder to work.
