i have created reference library (dll) contains testing utilities use multiple users. library stored on our tfs users can contribute , gain access it. however, seems way each user reference library create copy of library on local machine , make reference location. whenever makes changes library, user must make new copy of file onto local machine. in mind, seems silly. there way each user can reference library within tfs itself, rather having create new copy of each time there changes made? create nuget package. if search around sharing code between solutions, advice. tfs not network drive.
