Missing System.Drawing .NET 4.5 VS 2k12

Question

I have a web project in Visual Studio 2012, with 4.5 as target framework. Now I wanted to use System.Drawing, the reference is there (by default, I did not add it) but it has a yellow icon next to it. When building this is my errormessage:

1>C:\\Windows\\Microsoft.NET\\Framework\\v4.0.30319\\Microsoft.Common.targets(1605,5): warning MSB3267: The primary reference "System.Drawing", which is a framework assembly, could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.5". To resolve this problem, either remove the reference "System.Drawing" or retarget your application to a framework version which contains "System.Drawing". 1> DrawingTest -> D:\\Project\\DrawingTest\\DrawingTest\\bin\\DrawingTest.dll

It looks like it is looking for a 4.0 assembly?

how can I resolve this?

(I tried remove/add reference)
