I have installed the Community TFS Build Activities 220.127.116.11 on several machines without issue. Then yesterday I tried to install version 18.104.22.168 for a client and found I could not add some of the Activities to the toolbox.
We could load some of the DLL's but not all.
For example when we try to add TFSBuildExtensions.Activites.dll to System.Workflow Components we get the message:
System.Exception: There are no components in TFSBuildExtensions.Activites.dll that can be placed on the toolbox. If you are working with the 4.0 based activities then please try the System Activities Components tab.
So we did that and we get the same message but it says to try adding them to System.Workflow.
Any help would be appreciated.
