I see many questions like this popup on stackoverflow, or even beginner .net programmers asking this question. Many of them worded differently, but asking the same thing. “How do I reference other projects in visual studio”. You can find a worded version on MSDN or you can view the pictorial version below:
Referencing the project
You can reference the project with all the source code, etc. You can make real-time changes here and the visual studio intellisense will reflect those changes, even before compiling the other project.
You can create a whole new solution with just a class library project or you can add a class library to an existing project(silverlight will contain their own type of class library as they use a subset of the .net framework):
You need to reference this project:
If its already in your solution, just view the Projects tab and you’ll see a list of projects you can reference:
It should then be listed in your reference folder:
Referencing an assembly
You can also reference the compiled dll or any other assembly (.exe) you wish. (Which is what referencing a project actually does, it just points the reference the other other project’s build output directory). Just do as you would with referencing a project, but just browse for a the file. When referencing a built assembly, you loose debugging features (unless you want to debug the IL), but no C# or higher level language debugging is available.
