I have a Visual Studio project in one folder, say C:\project_name\app_name.csproj and it has a structure like C:\project_name\controllers. I want to tell this project file to always look into a carbon copy structured folder, say C:\custom_project_name\controllers\ to see if there are any files in there, and, if so, override what is in the base project. This would not compile the customized file in the base project. It would instead use teh custom project's version of the same named file.
Is this possible? Sorry in advance if this is somehow a duplicate, but I do not even know what to call this when searching for an answer out there.
