Visual Studio do not add my component (from a DLL)

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 tried following the other answers (thanks to all of you!), but I got this problem and I'll let you all know how I solved it and show my custom tools in toolbar (in VS 2017).

1. Place the .ddl file in any Library Solution
2. Then I add that .ddl as reference to my needed project
3. Build the project and restart the Visual Studio

4. Then, when I look into toolbox, my custom toolbox name appears in toolbar, when I expand that I got below message

   There are no Usable controls in this group. Drag an item onto this text to add in to toolbok

   

5. I dragged the .dll and dropped under that text and then all my custom tools appeared in my toolbox.
