Custom controls disabled. There was an internal issue with the rendering process

问题

I installed Xamarin 4.2.2.11 (00fa5cc) on VS 2013.

How can I solve this error in designer: Custom controls disabled. There was an internal issue with the rendering process.

This is my sdk manager

This is the designer.
