Many times I have seen Visual Studio solutions which have multiple projects that share source files. These common source files are usually out in a common directory and in the solution explorer their icon shows up with a link arrow in the bottom left.
However, any time I try to add a source file to the project that is outside of that project’s main directory, it just automatically copies it into the directory so that I no longer have a shared copy.
I found that I can get around this by manually opening the project file in a text editor and modifying the path to something like ‘../../../Common/Source.cs’ but this is more of a hack then I would like.
Is there a setting or something I can change that will allow me to do this from within the IDE?
Right click on a project, select Add->Existing Item->Add as link (press on small arrow on Add button)
