[RESOLVED] Inconsistent Accessibility: base class WorkItem is less accessible than class...

Hello, I'm following a tutorial at Inheritance (C# Programming Guide) | Microsoft Docs and I'm getting this error:

Inconsistent Accessibility: base class WorkItem is less accessible than class ChangeRequest

What's going on here? I've come accross with this before on that site. Here's a part of the code:

VB.NET Code:

namespace Business
{
    // ChangeRequest derives from WorkItem and adds an item (originalItemID)
    // and two constructors
    public class ChangeRequest : WorkItem
    {
        protected int originalItemID { get; set; }
        ...

The line of code

Code:

---

public class ChangeRequest : WorkItem

---

is declaring a public class called ChangeRequest that inherits WorkItem. If you want to make ChangeRequest public then WorkItem would also need to be public, I would check the WorkItem class and see if it is public or not.

Oh I forgot to add "public" in the other class. Thanks a lot.
