Few @angular packages are not retrieved from api

Tested in both 4.0.6 and 4.0.11 version,

The following packages are the ones we’re attempting to consume:

"@angular/common": "^2.0.0-rc.1",
"@angular/compiler": "^2.0.0-rc.1",
"@angular/core": "^2.0.0-rc.1",
"@angular/http": "^2.0.0-rc.1",
"@angular/platform-browser": "^2.0.0-rc.1",
"@angular/platform-browser-dynamic": "^2.0.0-rc.1",
"@angular/router-deprecated": "^2.0.0-rc.1",

All of them have the same issue which is that proget doesn’t like the @ in the name.

You can see the bug in action if you do an http request to the server:

I have given you the URLs which works with npmjs registry not with proget.

https://SERVERNAME/npm/DefaultNPM/@angular%2Fcommon
fails
error it throws "{"error":"ArgumentException","reason":"String is not a valid semantic version."}"

https://SERVERNAME/npm/DefaultNPM/es6-promise
succeeds

Performing the same requests to the public npm server works correctly:

https://registry.npmjs.org/@angular%2Fcommon
succeeds

https://registry.npmjs.org/es6-promise
succeeds

Please let us know, if there is a fix available in any builds.

Version: 4.0.6
