title: How to Export internal class in VisualStudio MEF
body: <p>Is there anything to do when I would need to export my service, so that I could make use of VisualStudio / Roslyn components but the interface is internal?
  I cannot implement internal interface nor can I export it.</p>
  
  <p>I am well aware that it is internal because it is likely to change and not meant to be used yet. And it could be gone by update 2. This is where unit testing comes into play.</p>
  
  <p>I have good reason for that and already opened this issue here:
  <a href="https://github.com/dotnet/roslyn/issues/9135" rel="nofollow">https://github.com/dotnet/roslyn/issues/9135</a></p>
  
  <p>Do you have any idea how to bypass that?</p>
