I’ve been using Click Once for longer while now and it was easy to deploy applications to my customers. But lately I decided it’s time to move on as there are things that I simply can’t fix in ClickOnce deployment (like ngen Devexpress libraries).

So I would like to move to WiX but I was wondering if I really have to 

<DirectoryRef Id="INSTALLLOCATION">
  <Component Id="Executable.exe" Guid="{C4DCEDD2-B4FF-4DFB-B7D6-2FA8B16D7740}">
    <File Id="Executable.exe" Source="C:\MySourceFiles\Executable.exe" KeyPath="yes" Checksum="yes"/>
  </Component>
  <Component Id="documentation.html" Guid="PUT-GUID-HERE">
    <File Id="documentation.html" Source="C:\MySourceFiles\documentation.html" KeyPath="yes"/>
  </Component>

  ... each dll goes here
  ... each xml goes here
</DirectoryRef>

Do I have to really go thru 70+ files and put one by one and generate GUID for it? Can’t it autogenerate it from Directory or something and then eventually I could just fill it in? Or am I doing something wrong?

    No you don’t you can use the harvest tool heat to generate wxs files. See http://wix.sourceforge.net/manual-wix3/heat.htm for more info. There are more features in the latest build of 3.6 that are not documented here so check the help for your version.
