How do I autoincrement Xamarin Android build and version numbers in Azure Pipelines?

Question

I looked at the official documentation and couldn't find much,

Xamarin.Android
Build an Android app with Xamarin
task: XamarinAndroid@1 inputs:
#projectFile: '**/*.csproj'
#target: # Optional
#outputDirectory: # Optional
#configuration: # Optional
#createAppPackage: true # Optional
#clean: false # Optional
#msbuildLocationOption: 'version' # Optional. Options: version, location
#msbuildVersionOption: '15.0' # Optional. Options: latest, 16.0, 15.0, 14.0, 12.0, 4.0
#msbuildFile: # Required when msbuildLocationOption == Location
#msbuildArchitectureOption: 'x86' # Optional. Options: x86, x64
#msbuildArguments: # Optional
#jdkOption: 'JDKVersion' # Options: jDKVersion, path
#jdkVersionOption: 'default' # Optional. Options: default, 1.11, 1.10, 1.9, 1.8, 1.7, 1.6
#jdkDirectory: # Required when jdkOption == Path
#jdkArchitectureOption: 'x64' # Optional. Options: x86, x64

It feels like I am missing something since incrementing the version and build is required by Google Play Store and will need to be done on each release by everyone.

You have to set this in manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="string"
          android:sharedUserId="string"
          android:sharedUserLabel="string resource" 
          android:versionCode="integer"
          android:versionName="string"
          android:installLocation=["auto" | "internalOnly" | "preferExternal"] >
    . . .
</manifest>

You can use token replace extension as follows:

variables:
  major: 1
  number: $[counter(variables['major'], 100)]

steps:
- bash: echo $(minor)
- task: qetza.replacetokens.replacetokens-task.replacetokens@3
  displayName: 'Replace tokens'
  inputs:
    targetFiles: |
      **/AndroidManifest.xml 

with file like this:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="string"
          android:sharedUserId="string"
          android:sharedUserLabel="string resource" 
          android:versionCode="#{number}#"
          android:versionName="string"
          android:installLocation=["auto" | "internalOnly" | "preferExternal"] >
    . . .
</manifest>
