Fody：发生未处理的异常

Question

I recently tried to build a xamarin project and got a Project.dll.mdb not found error. I solved this by updating to the latest version of Xamarin.Forms . Now I get this new error I suspect is relate to pdb and mdb:

I'm very new at Xamarin, so any help is appreciated. Thanks.

Sometimes I have errors with PropertyChanged.Fody (I don't know if it's the "Fody" you are using). Removing the package and reinstalling it, error should disappear
