Adding a .tlb as a reference
<p>I have a c# sample project provided by our client. But when I try to compile, I get an error with the .tlb file. It seems It cannot detect it as a assembly reference. I tried converting the .tlb file to COM library. I still cannot add. </p>

<p>The error message is showing something like this</p>

<blockquote>
  <p>A reference could not be added</p>
  
  <p>The Activex type library was exported from a .NET Assembly and cannot be added as a reference</p>
  
  <p>Add a reference to a .NET Assembly instead.</p>
