In project.json source, ignore, preprocess etc should be arrays

[victorhurdugaci]

Is there any particular reason why we use semicolon separated values in project.json instead of json arrays?

Today:

{
  "code":"Program1.cs;Program2.cs",
  "exclude":"Ignore1.cs;Ignore2.cs",
  "dependencies" : {
   },
   "configurations":  {
     "net45" : {},
     "k10": {
       "dependencies": {
         "System.Runtime": "4.0.20.0",
         "System.Console": "4.0.0.0"
       }
     }
   }
 }

Why not?

{
  "code":["Program1.cs","Program2.cs"],
  "exclude":["Ignore1.cs","Ignore2.cs"],
  "dependencies" : {
   },
   "configurations":  {
     "net45" : {},
     "k10": {
       "dependencies": {
         "System.Runtime": "4.0.20.0",
         "System.Console": "4.0.0.0"
       }
     }
   }
 }

Keys that should use arrays:

• code
• exclude
• preprocess
• shared
• resources (?)
