title: Custom HTMLControl derived from HtmlImage control not visible in VS2008 toolbox
body: <p>I have a custom control deriving from HtmlImage control which I cant get to show up on toolbox, it says "There are no components in '...\bin\Debug\ImageCustomControl.dll' that can be placed on the toolbox.".</p>
  
  <p>Here is the code for the control:</p>
  
  <pre><code>namespace ImageCustomControl
  {   
      public class ImageHtmlControl : HtmlImage
      {
          public override void RenderControl(HtmlTextWriter writer)
          {
              this.Src = "https://somedomain.com" + this.Src;
              base.RenderControl(writer);
          }        
      }
  }
  </code></pre>
