SSIS Script Transformation Editor -type or namespace name 'WebScrape' could not be found are you missing a using directive or an assembly reference?

Question

I'm using VS 2019 with SQL Server 2017. I have a SSIS Package and a Script Transformation Editor that is executing some c# code.

This is the main.cs:

#region Namespaces
using System;
using System.Data;
using Microsoft.SqlServer.Dts.Pipeline.Wrapper;
using Microsoft.SqlServer.Dts.Runtime.Wrapper;
using System.Windows.Forms;
using WebScrape;


#endregion

[Microsoft.SqlServer.Dts.Pipeline.SSISScriptComponentEntryPointAttribute]
public class ScriptMain : UserComponent
{
    
       

    public override void PreExecute()
    {
        base.PreExecute();
        /*
         * Add your code here
         */
    }

    public override void PostExecute()
    {
        base.PostExecute();
        /*
         * Add your code here
         */
    }

    public override void Input0_ProcessInputRow(Input0Buffer Row)
    {
        try
        {
            WebScrape WBScrape = new WebScrape();
            Row.DescriptionText = WBScrape.read_text_page(Row.Links);
        }
        catch (Exception UnknownError1)
        {
            MessageBox.Show(UnknownError1.Message);

        }
    }

}

This is the WebScrape.cs:

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

namespace SC_68c409392de64cb2b3012e25a1dc514c
{
    class WebScrape
    {
        const string HTML_TAG_PATTERN = @"(<(!--|script) (.|\n[^<]) * (--|script)>)|(<|&lt;) (/?[\w!?]+)\s?[^<]*(>|&gt;)|(\&[\w]+\;)";

        private string StripHTML(string inputString)
        {
            return Regex.Replace(inputString, HTML_TAG_PATTERN, string.Empty);
        }

        public string read_text_page (string pagelink)
        {
            string tempstring = string.Empty;
            int count = 0;
            string hold_temp_values = string.Empty;

            // used to build entire input
            StringBuilder sb = new StringBuilder();

            //used on each read operation
            byte[] buf = new byte[8192];

            //prepare the web page we will be asking for
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(pagelink);

            request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.99 Safari/537.36";

            // execute the request
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            // we will read data via the response stream
            Stream resStream = response.GetResponseStream();

            do
            {
                // fill the buffer with data
                count = resStream.Read(buf, 0, buf.Length);

                // make sure we read some data
                if (count != 0)
                {
                    //transalate from bytes to ASCII text
                    tempstring = Encoding.ASCII.GetString(buf, 0, count);

                    // continue building the string
                    sb.Append(tempString);

                }

            }
            while (count > 0); // any more data to read?

            hold_temp_values = StripHTML(sb.ToString()).Trim();

            if (hold_temp_values.Length > 8000)
            {
                hold_temp_values = hold_temp_values.Substring(0, 8000);

            }

            else
            {

            }

            return hold_temp_values;

        }
    }
}

When I try to build the project I keep receiving the error in the Main.cs:

Severity Code Description Project File Line Suppression State Error The type or namespace name 'WebScrape' could not be found (are you missing a using directive or an assembly reference?)

Why is it complaining? I have a WebScrape class created and I'm referencing WebScrape in the Namespace in Main. I have also tried referencing the fully qualified namespace in Main.cs to no avail:

using WebScrape.SC_68c409392de64cb2b3012e25a1dc514c;

What am I missing?
