title: Visualize the class structure in a .NET dll
body: <p>I get a library with two DLLs, but without the detailed document. I want get a quick view of its class design. </p>
  
  <p>I know that I can use the Object Browser in Visual Studio to look into them. But it is not very intuitive. Is there a tool that displays the dependency graph of the library, or more formally the UML diagram. The input is just the DLL. </p>
  
  <p>Thanks. </p>
