We just implemented TFS in our company and I accidentaly included the bin and obj folders. I would like to exclude them. I searched on Google and found basically 2 ways to accomplish this:

1) <https://msdn.microsoft.com/en-us/library/66tw9ezk(v=vs.90).aspx> 

**In Visual Studio, open Solution Explorer and select the file to exclude.
On the File menu, click Source Control, then click Exclude from Source Control.
When you are ready to place the file under source control, you can access the File menu and click Source Control, then uncheck Exclude from Source Control.**

In my File>Source Control, I don't see exclude from source control there or under advanced.

2) [How do I permanently exclude the bin and obj folders from TFS 2012 checkin?](https://stackoverflow.com/questions/21260039/how-do-i-permanently-exclude-the-bin-and-obj-folders-from-tfs-2012-checkin)

I tried adding a .tfignore and I couldn't find the 'ignore by extension', 'ignore file', etc. in teh Promote Candidate Changes dialog box. As far as I understand this is only applies to a local workspace and not a server workspace. 

We set up the solution to checkout a file whenever it's altered, so when someone builds the project he acquires an exclusive lock on the dlls and then nobody else is able to compile.
