Angular2 build error TS2305

I tried to run build on an angular2 project, inside a .NET project (this part doesn't matter a lot i think).

I encounter the following error when building my project. Already tried to delete typings directory and then do typings install with no change.

Too long for a comment:

I just took a like at an angular-cli package.json, and I see some differences. Note the import of @angular/compiler-cli. It's a guess, but "compiler" and all your problems with types could be related. Maybe your versions are old/off (I see in your script @angular/compiler instead of compiler-cli, etc).

(Changed post to include the whole package.json contents):
