Hello, I have the same issue.

This issue i have it when update a Xamarin.Forms version 2.4.0.280.

[DottorPagliaccius]

Tried with latest alpha version (2.0.0-alpha10), it works.

[HappyTreesDev]

I am also seeing this issue. The version of Xamarin.Forms pushed today did not fix it. 2.4.0.282

[Im-PJ]

I'm also seeing this error after updating to latest XF. Updated pulltorefresh to alpha version (2.0.0-alpha10) and it works.

[jamesmontemagno]

2.0 is now live and built against the latest XF and .NET Standard yay!

Thank you ;)
