Handling common classes in multiple projects in a single solution

Question

I currently have two projects say project A and project B in my solution. Now both projects A and B are using similar classes and a copy of each class is found in each project. I wanted to know if there is a better way to accomplish this task. I want to have a single class somewhere and have both projects access common classes from there. What is the recommneded way to do this.

Answer 1

1. Create a third project C in the same solution.
2. Add your shared classes to C.
3. Reference C in the projects A and B. (to do so : in the Solution Explorer , right click on References in project A and B, click Add Reference , click on tab Projects , then select Project C, click OK )
4. Don't forget to add the correct using namespace to use the class in the project A and B.

Or just let your shared classes in project A, or B and add reference to this project in the other project (It depends on the content but doing this way will create a kind of assymetry between the projects A and B).
