Visual Studio do not add my component (from a DLL) to the toolbox even if I reference it

Question

As stated in the title, I copied my DLL in Visual Studio project, set it to "content" and "copy always". Added a reference to this DLL and set it to "copy locally".

I successfully managed to instance my component to a form through code but it doesn't appear in the toolbox, really boring.

How can I solve this issue?

If I link directly the DLL project to this project it works, but now I'm treating the DLL as "external" so it's not part of the same solution of the DLL project.

I had this problem with @AndrewFinnell's solution:

There are no components in 'c:....\XXXX.dll' that can be placed on the toolbox.

So I solved with drag and drop:

• open Windows explorer and navigate to the DLL
• drag the DLL and drop it on Visual Studio in the Toolbox, exactly where you want your components to appear.

I also realized that some components may have compatibility issues with certain .NET Framework versions. For instance A Professional Calendar/Agenda View That You Will Use seems not to work with .NET 4.5, while it does with .NET 4.
