Sharing a common CS file throughout Multiple Projects?

I'm developing a small class which will be used in a number of distinct C#
projects. This small class is undergoing constant change/refinement as I
try to employ it in the different projects.

I'm trying to maintain a *single* copy of the CS file that can be used in
the multiple .NET projects. But I'm observing that when you add a CS file
to a given .NET project, subsequent modifications to that file are only
saved in the current project.

Perhaps I've added the common CS file to the projects improperly. I went to
the righthand project node pane for project A and right clicked, selecting
Add Existing. Then I browsed to the directory for project B and added this
common CS file. But again, modifications to that file made when I'm in
Project A don't make it automatically to Project B.

If anyone has an idea of how to share a common source file over multiple
projects, I'd love to hear it!

TIA

Hi Harry,

When you select Add Existing, don't click the Open button. Instead, click
the drop-down arrow beside the Open button and select "Link File".

As you can see from another answer, you can link the source code rather than
add existing.

I'm wondering, why not just compile the class into an assembly and reference
it from multiple projects? That's certainly the most "traditiona l" way to
do this, and it isn't more expensive in any way...

Joe -- Thanks so much! That's something I wouldn't have noticed!!

Thanks too to Nick. I'm finding that I have to tweak the source code of
this common module as I integrate it into the various projects. So I don't
think I'm ready to integrate it as a compiled resource because it's still
under development. (I hope I'm properly interpreting your suggestion.)

Hi ! What is the common use of sharing a single .cs across multiple project files ? I think it's to share common classes between projects. I have actually a .cs file shared accross multiple projects in a same solution. It's nice to have a common "set" of Classes. Is this the only way to share classes between projects ?

Within ASP.NET, is it possible to use a single .vb file and have it shared (or accessed) between multiple projects without having that file being copied to each project folder? ie. C:\Projects\MyProject1 (project 1) C:\Projects\MyProject2 (project 2) C:\Projects\CommonFiles\MyCommonFile.vb (common file directly accessed and compiled from Project1 and Project2)

I have a couple of files (type definitions, constants, ...) that I want to use in multiple projects. How do I make it so that I have only one copy of the file for multiple projects? If I do add existing to a project, it copies the file to the project directory. I'd like to have a single directory (called something like library) that has all the common source code in it that then gets referenced from the projects. TIA. Jeffrey.

Hi, I have two projects where I want to use the same source file in each project. If I add the file to each project, then a local copy is made. I want to be able to have a single source file used by both projects so that I only have to change one file. I am using compiler directives within the file, and so I can't just build it into a DLL and do it that way, I really do need to make both

Hi, We are developing a large modular application, and in order to simplify splitting of work between developers etc. we want to develop it using several different projects, and then combine the results into a single site.
