Finishing: Set Assembly Metadata

The tag becomes just v

However commenting out UpdateBuildNumber and AddBuildTag all works well and version number is set correctly to 1.4.8798.27461

#            UpdateBuildNumber: '$(Build.DefinitionName)_v$(appVersion)'
#            AddBuildTag: 'v$(appVersion)'

I guess this is due to the Major and Minor version numbers 1.4 are within the csproj and not captured and used in the build tagging and therefore just keeps the #.# in the build name and tag?

[furier]

Yeah updating yml pipeline to this works fine, so I guess build tagging also need to support # to keep part of version number

              UpdateBuildNumber: '$(Build.DefinitionName)_v1.4.*.*'
              AddBuildTag: 'v1.4.*.*'
