using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Activities;
using System.Activities.Presentation.Metadata;
using System.ComponentModel;
namespace MathCustomActivity
{
public class SimpleFormula : IRegisterMetadata
{
public string output()
{
return “Success”;
}
public void Register()
{

    }

}

Hi @Gopie,

Check with class name what you created in the custom activity.

For Example

you need to search in the activity tab like “SimpleFormula”

There is no custom activity in that code, just a normal class.
An activity is a class that inherits from Activity, CodeActivity, NativeActivity or their generic counterparts or subclasses.

Hi @arivu96,

Thanks for your reply.

I have created the custom activity with your same code shared with me previously. Below the custom code. So only i have searched that activity in studio as " Addition1". But still facing same issue.

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

namespace Addition
{
public class Addition1 : CodeActivity
{
[Category(“Input”)]
public InArgument value1 { get; set; }

[Category("Input")]
public InArgument<int> value2 { get; set; }

[Category("Output")]
public OutArgument<int> value3 { get; set; }

protected override void Execute(CodeActivityContext context)
{
    value3.Set(context, (Convert.ToInt32(value1.Get(context)) + Convert.ToInt32(value2.Get(context))));
}

}
}

Thanks & Regards,

Hi @Gopie,

you used correct code only.

Try to install this package and try again

May be you did something wrong in converting into package i think so.
