In my xaml I have:
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:Opa"
xmlns:maps="clr-namespace:Xamarin.Forms.Maps;assembly=Xamarin.Forms.Maps"
x:Class="Opa.MainPage">
<maps:Map MapType="Street" />
...
</ContentPage>
The type 'maps: Map' could not be found. Make sure there is no assembly reference missing, and if all referenced assemblies were created.
But note that it is declared in the ContentPage header, in this line:
xmlns:maps="clr-namespace:Xamarin.Forms.Maps;assembly=Xamarin.Forms.Maps"
Why the error?
Edit1
My project is called Ola
So is my header
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:local="clr-namespace:Ola"
xmlns:maps="clr-namespace:Xamarin.Forms.Maps;assembly=Xamarin.Forms"
x:Class="Ola.MainPage">
<maps:Map MapType="Street" />
