title: How to create custom module for Microsoft Navision
body: <p>I'm a .Net developer and I'm trying to figure out how is it possible to build custom module for Microsoft Navision. The Navision community seems to be be a small and close one. I didn't find a lot of informations except from the mibuso.com website. </p>
  
  <ul>
  <li>Do you know other good source of informations ? </li>
  </ul>
  
  <p>After some search it appears that there is two possible way to create custom module on an existing Navision installation: </p>
  
  <ul>
  <li>Create dll that will be integrated in a way into Navision ? Any documentation ? </li>
  <li>Create external web applications that will access Navision data through WebServices ?</li>
  </ul>
  
  <p>Did someone have informations about that kind of development ? </p>
