How to add multiple solution reference in Visual Studio

Question

This is more like a beginner question, but till now I have worked on small C# projects and I know how to add a separate project.

I will create a class library, and add reference of it as per needed, and then I am good to go. I will have something like below:

Project Main -> references Project Temp1 
             -> references Project Temp2

But all this when built will form ONE .sln file.

Question: how can I link separate .sln ? So, I have 5 separate Visual Studio solutions, and I want to add reference, how to achieve it? Is it possible for one .sln file to link to another .sln file?

Edit : I created a sample application A1 , and another application B1 . And now when I go to Project A1 and click on Add reference why don't I see project B1 there?

Answer 1

Your screenshot shows the reference manager with item "Projects > (current) Solution" open. This list shows all projects in currently opened solution. To see your "B1" project here, add it to solution first:

• Solution Explorer
• Right click on Solution
• Add > Existing Project
