The attribute name of [ *ngIf ] must be in lowercase.(attr-lowercase)
Anyone looking to solve this from another IDE such as Eclipse or Codemix, simply create a file called .htmlhintrc place this in /<angular-project>/src/.htmlhintrc and change the values as you see fit, mine are:
{
"tagname-lowercase": false,
"attr-lowercase": false,
"attr-value-double-quotes": true,
"doctype-first": false,
"tag-pair": true,
"spec-char-escape": true,
"id-unique": true,
"src-not-empty": true,
"attr-no-duplication": true,
"title-require": true
}
