Actual behavior

Loading binaries from the console project instead of mvc, but runs the mvc.dll
Loaded 'C:\Program Files\console \shared\Microsoft.NETCore.App\2.0.1\System.Private.CoreLib.dll'. Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.
Breakpoint warning: A copy of Program.cs was found in dotnetmvc.dll, but the current source code is different from the version built into dotnetmvc.dll.
To allow this breakpoint to be hit: Add '"requireExactSource": false' to launch.json and restart debugging. - e:\VsCodeTest\console\Program.cs:9
