Visual Studio 2017将无法编译Xamarin跨平台项目

Question

I am getting a bunch of errors

"The type or namespace name 'Forms' does not exist in the namespace 'Xamarin' (are you missing an assembly reference?)".

What I have tried is updating the Xamarin.Android.Support packages but it fails to update to 26.1.0.1. Current version installed is 25.4.0.2.

I also tried Clean Solution and Build Solution, but no success. I believe I am only getting these errors on Cross Platform mode because I was able to compile and run on Android project only. How do I fix this issue?

Answer 1

I tried the usual things. Clean the build. Restore Nuget Packages. I tried to clear the Nuget cache via the Tools -> Nuget Package Manager -> Nuget Package Settings, but after a long wait I got an error. Out of desperation I decided to update the Nuget Package Automapper from version 7 to 7.01. As far as the errors were concerned Automapper was completely irrelevant. And yet it worked, I could suddenly compile again. Amazing. Maybe this cleared the Nuget cache? Well next time this happens I will do something similar - maybe change the Automapper version back to 7 again and see if that works. It did this time.
