NuGet and debugging through source code with the Source Link
If you're using your own NuGet packages or consuming 3rd party ones, then you've probably faced the pain of stepping (or rather not stepping) through it's source code.
Forget the symbol and source servers, there's a new and friendlier kid on the block: Source Link. Formerly you had to upload your symbol (PDB) and source files to different locations and use several switches during the build. Even that didn't guarantee you success, downloading source files often failed miserably.
Source Link is here to ease your pain, it is a developer productivity feature that allows unique information about an assembly's original source code to be embedded in its PDB during compilation.
