title: Cryptographic failure error and metadata file for dll error
body: <p>We have purchase one software from another company with source code. But when i build it, following two errors had occurring. I researched lot on it. But cant find solution. Generally <code>.snk</code> files are for DLLs (to add it in GAC global assembly cache) i can't found <code>PublicPrivateKeyFile.snk</code> in app folder or anywhere. Application references number of dlls,so same error is shown for every DLL. What should i do to resolve this errors.</p>
  
  <pre><code>Error Cryptographic failure while signing assembly ...\obj\Debug\xyz.dll' -- 'Error reading key file 'c:\Users\Administrator\Desktop\NewCode\abc\Libs\PublicPrivateKeyFile.snk' -- The system cannot find the file specified.` 
  
  Error metadata file 'C:\Users\Administrator\Desktop\NewCode\abc\bin\Debug\xyz.dll' could not be found
  </code></pre>
  
  <p>What is metadata file?
  How to resolve both errors?</p>
