Cinemachine 'DocumentationSortingAttribute' does not contain a constructor that takes 2 arguments

Hello,

I am using Unity 2019.3.6f1 and I am trying to work with the kart game from Unity sample templates and when I open the editor I get this error:
Assets\Cinemachine\PostFX\CinemachinePostProcessing.cs(30,6): error CS1729: 'DocumentationSortingAttribute' does not contain a constructor that takes 2 arguments

Here is the code:

Code (CSharp):

1. namespace Cinemachine.PostFX
2. {
3.      /// <summary>
4.      /// This behaviour is a liaison between Cinemachine with the Post-Processing v2 module.  You must
5.      /// have the Post-Processing V2 stack asset store package installed in order to use this behaviour.
6.      ///
7.      /// As a component on the Virtual Camera, it holds
8.      /// a Post-Processing Profile asset that will be applied to the Unity camera whenever
9.      /// the Virtual camera is live.  It also has the optional functionality of animating
10.      /// the Focus Distance and DepthOfField properties of the Camera State, and
11.      /// applying them to the current Post-Processing profile, provided that profile has a
12.      /// DepthOfField effect that is enabled.
13.      /// </summary>
14.      //ERROR IS IN THIS LINE:
15.      [DocumentationSorting(101, DocumentationSortingAttribute.Level.UserRef)]
16.      [ExecuteInEditMode]
17.      [AddComponentMenu("")] // Hide in menu
18.      [SaveDuringPlay]

I hope someone can help me fix this.

Thanks.

 

I have the same problem. Did you manage to fix it?

 

Check if there is an update to the cinemachine package.

 

I have the same issue. Any responses??

 

As @Kurt-Dekker said, you likely need to update Cinemachine.

 

Necro time: I have updated cinemachine, and the error persists

 

When you provided a constructor for your class that takes arguments, the compiler no longer creates an empty constructor. Therefore, you cannot call an empty constructor because it does not exist. You would need to explicitly write the constructor that takes 0 arguments in your class's code. The constructor of the inheritance class needs to construct the base class first. since the base class does not have a default constructor (taking 0 arguments) and you are not using the non-default constructor you have now, this won't work. so either:

• Add a default constructor to your base class, in which case the code of the descending class needs no change;

Or

• Call the non-default constructor of the base class from the constructor of the descending class, in which case the base class needs no change.
