How to: Set the Reference Path (C#)
When you reference an assembly in your project, Visual Studio first searches for the assembly in the project directory. If you use an assembly not located in the project directory, you can specify its location in the Reference Paths pane of the Project Designer.
Note
The procedure for setting the reference path for Visual Basic projects is slightly different. For more information, see How to: Add or Remove References in Visual Studio.
Note
If the reference to the assembly is not in the project or listed in the Reference Paths pane of the Project Designer, Visual Studio checks the directories that display files in the Add Reference dialog box.
You can add as many reference paths as you need.
Note
Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. For more information, see Visual Studio Settings.
