The debug information generated for razor files uses relative paths for source line information. The debugger needs full path information in order to find the file to open.

Example

1. Get the Microsoft C# extension for VS Code
2. Get, restore and build cli-samples/HelloMvc
3. Open HelloMvc in VS Code and create a launch.json (example)
4. Set a breakpoint on Views/Index.cshtml line 4 and launch

Expected

VS Code breaks at the breakpoint and displays locals/watch expressions

Actual

VS Code breaks into no source page and cannot display locals/watch expressions
