How to add breakpoint in another solution in Visual Studio?

Question

I am working with Visual Studio 2015.

I have a solution Sol_Base which has multiple projects Proj_Base_Web, Proj_Base_Bo and Proj_Base_DA. All these projects are class libraries. These are considered Base projects .

I have a solution Sol_App which has multiple projects Proj_Web, Proj_BO, Proj_BL and Proj_DA. Proj_Web is ASP.NET Web Application while other projects are class libraries.

Sol_App has reference to the Base projects. Lots of objects in projects of Sol_App extends from objects of Base projects. I run the app through Sol_App.

I can add breakpoints in projects of Sol_App so I can debug it when running the app. But I want to be able to debug the code in Base projects as well while running the app. Which means I want to add breakpoints in projects of Sol_Base. How can I do that so that they become into play when I am running the app?

Thanks

Answer 1

You can debug one reference project(class library) in two solutions using attach to process in your side.

Reference:

Debug Multiple Solutions VS 2012

Another suggestion is that add them to a single solution would be also a workaround for it. Or copy the debugging file manually:

The quickest way to do this on a one-off basis is to open the Proj_Base file directly in the Visual Studio instance in which you are editing and launching Sol_App (File => Open => File). You don't need to add the file to the solution. Just having it open in the editor will let you create your breakpoints.
