title: Visual Studio - Attach source code to reference
body: <p>My C# project references a third-party DLL for which I have the source code. Can I somehow tell Visual Studio the location of that source code, so that, for example, when I press <kbd>F12</kbd> to open the definition of a method in the DLL, it will open up the source code, instead of opening up the "Class [from metadata]" stub code?</p>
