Harvesting wix files
Back | wix | 4/14/2010 | Tweet
Sometimes great is the enemy of good. I recently had to harvest a large number of files to create a wix installer. I tried heat.exe, but after struggling with its generation style and even considering writing an XSLT, I decided it would be faster to just code what I want in C#. This generates a .wxi file that follows somewhat of a standard of naming components .C, directories .D and skipping .svn folders.
It just gets the job done.

id = parent.Attributes["Id"].Value.Replace(".D", "") + ".";
id += dir.Name + ".D";
directory.Attributes.Append(doc.CreateAttribute("Id")).Value = MakeId(id);
