In the document Xamarin.Essentials: Permissions https://learn.microsoft.com/en-us/xamarin/essentials/permissions?context=xamarin%2Fandroid&tabs=android
The following line is included in a code snippet
if (Permissions.ShouldShowRationale<Permissions.LocationWhenInUse>())
ShouldShowRationale does not exist in the essentials package. Is there some other way to get it or is this aspirational code rather than real code?

2020-11-24T16:49:46.883+00:00 @James Montemagno Thanks. The minimum version should be noted in the document. Also, it compiles now and runs now, BUT I am trying to prompt for camera permissions and the following does not issue a prompt.
status = await Permissions.RequestAsync<Permissions.Camera>();-

2020-11-24T16:52:01.69+00:00 If it is in preview then it is in the pre-release. The docs don't have the concept of a minimum version right now, but somethign we are looking into.
Did you add the information into your manifest on iOS/Android/UWP?
Also on iOS if it already was prompted once then it wont prompt again.

2020-11-24T17:04:58.7+00:00 Yes. I did. (But, I am not compiling for iOS at this time.
Also, while the docs don't have a concept of minimum version (a big problem on the API docs), as a frequent doc writer at Microsoft I have included statements such as this:
General Usage
The following presents the general usage pattern for determining whether a permission has been granted and requesting it if it has not. This code snippet uses features that are available with Xamarin.Essentials versions 1.6 and higher.

2020-11-24T18:54:09.997+00:00 Ok, figured out the issue. I had to change how I was calling my method that called the method to check permissions.
I had been calling it (from when I was using Plugin. permissions):
Task.Run(() => spp.CameraPermissions());
changed it to:
PermissionStatus status = await spp.CheckAndCameraPermission();
And everything appears to be working correctly now.
Thanks for your help.
