This is because you ended your project with the word .Android. This causes an issue with the namespaces of Android, so it thinks your app is the Android namespace instead of the Android APIs. Recreate your project so it doesn't have Android try Droid.

@jonathanpeppers is there anything in the IDE we can do to make sure this doesn't happen ^

[jonathanpeppers]

I tried with the dotnet new templates we are working on for .NET 6 here: dotnet/android#5348

> mkdir Foo.Android
> cd Foo.Android
> dotnet new android
> dotnet build

And it seems like it works fine at the moment, but these templates are really simple. I'll make sure we have a test where the name includes .Android -- so we can make sure this works going forward.
