If you are like me and you create a number of Custom Build Activities for TFS you want to ensure that you keep them in a tidy place.

The best place I have found is to find the BuildProcessTemplates folder and add a new folder called CustomActivities, and in this folder place all your xaml and dll’s files that you have created.

Once you’ve created the new folders and files you’ll need to make sure the build controller know about them, click Build > Manage Build Controllers then select the properties and enter :

$/Microsoft/BuildProcessTemplates/CustomActivies

under the Version control path to custom assemblies.
