Deprecation notice

Azure DevOps Server is deprecating the old work item APIs. They are likely not going to be removed any time soon, but we can't keep supporting this plugin version forever.

Our recomendation is to migrate to aggregator-cli which can now be hosted on Azure Functions or in Docker.

We won't do any major investment in this Plugin version and our bandwidth for support is limited.

This server side plugin, for TFS 2013 update 2 up to TFS 2018.3 and Azure DevOps Server 2019 and 2020, enables running custom script when Work Items change, allowing dynamic calculation of field values in TFS and more. (For example: Dev work + Test Work = Total Work).


The complete documentation is available on the project's Documentation Site.
