Background
I created a new project with Microsoft's Team Foundation Service (tfs.visualstudio.com). I added code (Orchard CMS) which includes the solution file and performed initial check-in. To make sure nothing was missed, I removed mappings and deleted my local. Then got latest and reestablished mappings. I opened the solution, built it and set up a local site. Everything worked fine.
Issue
Whenever I open/load the solution, I noticed that I don't have the usual TFS options like get latest, check-out and check-in and source control options. Then I noticed an add to source control option (see below)
Whenever I click on it, I get told that the 'item 'Orchard.sln' is already under source control'
Without source control, I don't have the options and I can't track which files have been updated or not, and the locks as well. Can anyone help please?
