How to solve this error? - 'Resource.Layout' does not contain a definition for axml file

Question

Am new to Xamarin and is currently building a very simple app using the tutorial from Youtube. Am just in a middle of the video when I got this error even tho I carefully followed all instructions. And even the instructor in the video was able to run his app successfully

Here's the code where I'm getting the error:

var view = inflater.Inflate(Resource.Layout.SignUp, container, false);

Answer 1

For me it is caused by namespace changes. After I corrected the namespace in project properties, then I can build again

Answer 2

I just deleted my newly created axml file, rebuild, add it again, and this time, clean and rebuild.

Everytime I added a new axml file, I clean and rebuild. That's all, thank you :).
