We are handling this scenario via automated query against a source control repository, rather than at a binary level of the compiled output. We investigated compiled output comparison as well, and it just was not a feasible solution for us.
We handled this with a service account that checks-in the version # into the notes in SVN when a build is performed on our build server. We keep our build server locked-down to contain our "binding" between the compiled output and the source code changes. We use standard naming conventions (project <Namesp.Assem> outputs <Namesp.Assem>.dll) to make it easy to see which .dlls have changed since release X. It's not perfect, but it works for us. The keys are locking-down the build server, using a service account, and keeping track of source-code to binary output mappings (or enforcing a naming convention to do this). We are using SVN as source control and Jenkins as our build server.

Subject: Re: [WiX-users] Patch building with Torch, all .NET assemblies "changed" When I was at SCX (Microsoft), we went so far as to investigate tools to compare only the "code" parts of an assembly--but in the end, that proved too cumbersome and unreliable, and so we just lived with the diff's between build. At ESA-JHA, a significant number of assemblies are checked into source control when they are updated using special, manual "promote" builds. These assemblies are thus not rebuilt except when they change--reducing the diff's in builds. But, an all-up complete rebuild is also sacrificed by this technique. There are always compromises. -- John Merryweather Cooper Build & Install Engineer - ESA Jack Henry & Associates, Inc.(r) Shawnee Mission, KS 66227 Office: 913-341-3434 x791011 jocoo...@jackhenry.com www.jackhenry.com -----Original Message----- From: Castro, Edwin G.

Subject: Re: [WiX-users] Patch building with Torch, all .NET assemblies "changed" My initial guess is that your assembly's versions are changing between builds. I'm very interested in a proposed approach to this as we have a build that results in changed versions on every build. I haven't personally investigated an approach to handle this yet. I haven't had the time yet to do it. Edwin G.
