Hi Rafael,
We regret for
the inconvenience caused.
It seems that

referred to your project targeting 4.0 Framework. We would like to let you know
that we do not have backward
compatibility support(we cannot use 4.5 Framework controls in the project targeting
4.0 Framework). But, we have Forward compatibility support(i.e. We can use 4.0 Framework
controls in the project targeting 4.5 Framework). So, if you wish to configure
4.0 controls in Visual Studio 2012 toolbox, then please refer the below mentioned
Knowledge Base article link.
