Now and then I get XamlC error XFC0000 : Cannot resolve type "PrismApplication" in the error list of my shared xamarin project. The error is from App.xaml and no squiggly is shown in that file, but the error is shown in the error list. Sometimes it goes away if a restart visual studio. I'm running Prism.Unity.Forms v7.2.0.1422. I shoud mention that my android project still builds when the error is shown, but it's annoying and I like to know how to remove it? Maybe it can be done like something like suppressing the error about Ambiguity between 'Resource.Layout.Tabbar' and 'Resource.Layout.Tabbar.

I am using Prism with DryIoc (and not unity). Following a suggestion from another thread I replaced
xmlns:prism="http://prismlibrary.com"
with
xmlns:prism="clr-namespace:Prism.DryIoc;assembly=Prism.DryIoc.Forms"
in my App.xaml file and the error disappeared.
I had the same error with PopupPage from Rg.Plugins.Popup, so I also replaced
xmlns:pages="http://rotorgames.com"
with
xmlns:pages="clr-namespace:Rg.Plugins.Popup.Pages;assembly=Rg.Plugins.Popup"
and that error disappeared as well.
As these are two different libraries, acting similarly, it might be a general VS issue. But could also be the same error in two libraries.
Another thread lead me to this article which basically says that using a custom namespace requires a direct reference to the assembly through C# code in order for VS to find it and not show this error.
You could ignore it. Click the Code of the Error List window and clear filter the error which you do not want to show.
Uncheck the error you want to ignore.
