I have a solution, which contains 7 projects.
I wanted to try out TFS (just to see how it works etc.), so I would like to add this existing solution to my TFS' DefaultCollection.
Is this possible without re-creating all the projects and adding their files?
Sure, just right click on the solution in Solution Explorer and select "Add Solution to Source Control".
For Team Foundation Service:
- Go to your http://.visualstudio.com
- Create a new Project via the website
- Open your solution in Visual Studio 2017
- Go to "Team Explorer" and double click the newly added project name from TFS (it is normally set in a gray color)
- Go back to "Solution Explorer" and to right mouse click on the solution and select "Add to source control"
- Right mouse click on the solution in "Solution Explorer" and select "Check in" for an initial check in to TFS
