title: The type library importer encountered an error during type verification
body: <p>I am writing a C# application which has several COM references. When I attempt to build it I get the following error for some of them:</p>
  
  <blockquote>
    <p>c:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets(1418,9): error MSB3303: Could not resolve COM reference "70850f66-869f-44a0-88e7-b0460a7e3bf3" version 0.1. The type library importer encountered an error during type verification. Try importing without class members.</p>
  </blockquote>
  
  <p>The application is still built and runs successfully.</p>
  
  <p>What does this error message mean, and how can I fix it?</p>
