title: Unable to find assembly file 'example.dll' while starting windows service
body: <p>I have developed a WCF service which uses the <strong>net.tcp</strong> binding and <strong>read</strong> and <strong>write</strong> files to the file system. When I start the windows service (in a console) I get following error even if the <strong>sample.dll</strong> is in the folder:</p>
  
  <p><strong>Unable to find assembly file sample.dll</strong></p>
  
  <p>This specific WCF service is hosted in a windows service which runs on windows 7 64bit and I have following questions:</p>
  
  <p>Which account should I use for my application: </p>
  
  <p><strong>User / NetworkService / LocalSystem / LocalService</strong></p>
  
  <p>And why can’t the OS load the dll even if it is there?</p>
  
  <p>Thank you in advance for your help!</p>
