I have a version properties file that during build I want to check out from TFS, update using FB actions, then check back in.
Check out is working fine
Update is working fine - The file is changes
Check in is failing with the following message:
"Unable to determine the workspace. You may be able to correct this by running tf workspaces /collection:TeamProjectCollectionUrl.
TFS is 2010. My local VS is 2012. FB .2179
The checkout works great but I cannot find anywhere to specify "workspace" other than to try and create one. I did try that and while that action succeeded the check in does not.
I also tried creating the new workspace before doing the checkout and removing it after everything is done with no luck.
Any ideas on how to get check in to TFS working?

I believe the step you are missing is to Map the Working Folder.
