I got two project in my solution in Visual Studio 2010.
Project 1 contains an app.config with a ConnectionString.
How can I access that ConnectionString from Project 2?
Since they are both using the same ConnectionString, I would prefer to only have one instance in my solution.
You can add the files as a link to the file to one of your projects.
Use
Add an Existing Itemto the project you want to add the file to – theOpenbutton has a small down arrow, if you click that you can selectAdd as Link.This will add the file as a link from the original location, meaning you only have one physical file.
