Roslyn: Unable to issue a `using System.Xml;`

[beruic]

Version Used:
Visual Studio Enterprise 2015 Update 2

Steps to Reproduce:

1. Open C# Interactive
2. Type in using System.Xml;
3. Press [Enter]

Expected Behavior:
The namespace would be imported

Actual Behavior:
Error:

``` C#

using System.Xml;
(1,14): error CS0234: The type or namespace name 'Xml' does not exist in the namespace 'System' (are you missing an assembly reference?)
```

Assembly System.Xml isn't included by default, so you must add the reference yourself:

``` C#

r "System.Xml"

```

BTW, you can see the default refs and imports if you open C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\PrivateAssemblies\CSharpInteractive.rsp
