Nice, now we are able to help are our clients take the last step in migrating from TFS to VSTS. Good work!
Recently discovered an excellent way to automate versioning of assemblies integrated in a TFS build definition. I followed the guide and instructions written at this code plex open source project
Then I created specific build templates including these options, so that creators and users of build definitions can edit all the versioning attributes a long side other customizations for two of our clients and they are very happy about it.
I really recommend this custom made build activities to all who need to automated assembly versioning included in their TFS build templates and definitions.
Good work guys!
