Can I debug into asp.net core source code?

Question

How can I attach the MVC 6 source code or dlls into my project so that I could debug into it. I need to see the actual flow of few things.

Answer 1

1. Clone the repo(s) that you want for debugging from GitHub
2. Add a global.json file to your solution, similar to the one here

3. In the sources property, add the path(s) to the src folders that you got from github. For example:

   {
       "sources": [ "src", "D:\\dev\\aspnet\\mvc\\src" ]
   }
   

4. Run and the sources in D:\dev\aspnet\mvc\src should be used instead of the NuGet packages from NuGet/MyGet.

PS: Make sure you are using the sources and the packages from the correct branch. Otherwise you might hit strange issues like the one described here

Answer 2

As of beta4, the sources node in global.json has been changed to projects.

{
    "projects": [ "src", "D:\\dev\\aspnet\\mvc\\src" ]
}
