Formally speaking, Solution 2 is perfectly correct. At the same time, the whole idea of using the same file across project is questionable, architecturally. Think about having one assembly referencing another one and sharing code in this way. It's not good to compile the same file twice, ever.

You can always avoid it. Dedicate one or more assemblies to some utility methods (for example) and use this assembly by other assemblies by referencing it. Longer way is often really shorter. :-)

Solution 2

i found the solution: Right Click on your project, "Add" -> "Existing Item...", select your *.cs file and click on Down arrow next to the "Add" button and select "Add As Link".
