When I check out a solution from TFS a get a lot of .partial-files all over the project.
They are not on the TFS-Server, just on my PC. Sadly some of them prevent my solution from running and I always have to delete them manually. Can I somehow prevent this? Where do they come from?
These files exist in the local path of your workspace but not added into source control. For the partial extension file, you can refer to this page for the meanings.
You can delete or ignore them directly. If you want to prevent it, you can also change the local path of your workspace, then you will not see the files.
Another option is creating a new workspace and using a different local path, then do a workspace mapping.
