Powershell script to make use of @CurrentIteration query token in TFS queries
September 29th, 2015
no commentsSince the introduction of Visual Studio 2013 update 5, a new query token (@CurrentIteration) is available to automatically identify the current iteration of your iteration path, based on today’s date. By using this query token in queries that are related to the current iteration/sprint, you will save a lot of time in managing those queries (as mentioned in my previous blogpost).
However, once upgraded to Visual Studio 2013 update 5 or higher, you have to manually update your queries to make use of this new @CurrentIteration query token. This may cost you a lot of time. For that reason, I’ve made a powershell script to automatically implement the @CurrentIteration query token for the shared queries of your team project (see the code below or the attached zip file). After downloading/unzipping, just specify your own values for the different variables and run the powershell script.
