Unable to add external .dll in OpenSpan toolbox

I am trying to add an external .dll into my automation project. For my learning I created a .dll (GetName) from a class library project and I am trying to add that in OpenSpan toolbox

Following are the steps that I followed:

1) I created a C# class library project with one public method name GetName(string firstName, string lastName) that returns string as "Full name is firstName + lastName"

I made sure that the class library project is also built on .NET Framework 4.6.1, the same framework in which i am building automation. Code is as attached

2) I build the class library project. Copied the .dll from bin\Debug folder and pasted it to C:\Program Files (x86)\OpenSpan\OpenSpan Plug-in for Microsoft Visual Studio 2015.

3) In my automation project I added a reference by referring to the .NET Component and selected GetName.dll

4) In my openspan project in Toolbox, I added the .dll reference by browsing the .dll

Now I am unable to view the .dll name or corresponding methods in Toolbox.

Please let me know what step I am missing to add this simple custom .dll in my OpenSpan toolbox.

Following is the code for GetName.dll for which I created a class library project with name GetName123

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace GetName123
public class GetName
public GetName()
{ }
public string GetFullName(string firstName, string lastName)
return "My full name is " + firstName + " " + lastName;


Any help would be appreciated. Please let me know what need to be done so that I can view this custom dll i.e. GetName in my OpenSpan toolbox.

Let me know if you need any additional information from my end.

Thanks & Regards,
