As briefly mentioned in another post, we have a specific “Reference Assemblies” folder on the Build Machines containing the latest version of each assembly issued from a successful Build. Assemblies in that folder, know as the “Latest” folder, can be used for “Continuous Integration” Builds. This post is about the pragmatic solution implemented to drop only the primary output of the Builds in that folder.

The output of a Build contains not only the assemblies and satellite assemblies issued from the compilation of the Visual Studio Projects (I.e.: assemblies part of the “primary output” as named in the Microsoft Setup Projects). It contains also a copy of all the referenced assemblies (file references) with the property “CopyLocal”=”True”.
It’s important for our purpose to only drop the primary output into the “Latest” folder, otherwise we could override the latest version of some referenced assemblies with a copy of the specific version found for the Build (e.g.: when targeting the Integration Environment, we use the promoted version on, the assemblies which are possibly not the latest).
We may not set “CopyLocal”=”False” on all the “file references” because MSTest needs a copy of those in the bin folder to be able to run the unit Tests (That would not be the case if we could find for MSTest an equivalent of the “ReferencePath” parameter of MSBuild).
We don’t have access to methods (or well described “algorithms”) to retrieve the exact list of assemblies part of the “primary output”. Such methods are only implemented in the Microsoft Setup Projects (Projects not supported, by the way, by MSBuild).
We don’t want all our developers to add MSBuild Scripts in their Visual Studio Projects to drop the “Targets” in the “Latest” folder.
Ex. copy “$(TargetDir)$(TargetName).???” “C:\RefAssemblies\Latest”
This is not only too error prone (like everything you request to a human developer), but it’s also not robust enough. It’s in our opinion impossible to maintain this with enough guarantee taking into account that developers can for example add support for new languages at any time. For each Project, in addition to the assembly $(TargetDir)$(TargetName).dll, we also have to drop the satellite assemblies (e.g.: <culture>\<assemblyname>.resources.dll”), etc…
The most generic solution we found to identify the assemblies part of the primary output, although quick and dirty, consists in parsing the FileListAbsolute.txt file generated by MSBuild itself and available in the “obj” folder. We “rely” so on direct output of Microsoft (the content of that file) and avoid to implement (and maintain) our own generic (and most probably complex) algorithm (“complex” because I have no idea how to detect satellite assemblies in a Visual Studio Project).
Notice: We may only drop the primary output of Builds in the “Latest” folder for “Continuous Integration” Builds or Builds targeting the Integration Environment (both using the latest version of the sources). Builds targeting Qualification, Pre-Production or Production use always a specific version of the sources instead of the latest version. Their purpose is indeed to fix a bug in the assemblies deployed in the targeted environment and build with older sources.
