How to enforce deriving classes to implement an abstract property but allow implementations to use child classes of the type?

I am trying to enforce all classes deriving from class EducationalUnit to implement a “Content” property. This property needs to be a key value pair where the key is an int and the value can be either another class implementing EducationalUnit or another class I have called ContentBlock.

in EducationalUnit class i try to define an abstract property to take an Int and any Object key value pair.

public abstract Dictionary<int, Object> Content {get; set;}

And in the inheriting classes try to implement it:

public class Course : EducationalUnit
    {
        public override Dictionary<int, EducationalUnit> Content {get; set;}
    
        public Course () {
            this.Type = "Course";
        }
    }

However, when I try to do this I get ‘Course.Content’: type must be ‘Dictionary<int, object>’ to match overridden member ‘EducationalUnit.Content’ [Domain]csharp(CS1715).

I assumed since all classes inherit from Object this should have worked. Can someone tell me what am I doing wrong and a potential approach to implement this?
