Xamarin Android versionCode gets set to 1 regardless of value in manifest

Describe the bug

In .net 6 RC1 SDK, the versionCode in Android that is output to obj and to the eventual package gets reset to 1, regardless of what I have set in the AndroidManifest.xml.

I’ve tried various alternatives to the MSBuild properties, e.g. enabling legacy treatment AndroidUseLegacyVersionCode, changing the pattern with AndroidVersionCodePattern or leaving them all out as per the dotnet new android template. My repro below is for out-of-the-box behaviour. Nothing I found would set the version correctly, it always got set to 1.

To Reproduce

1. Clone https://github.com/mungojam/xamarin-android-versioning-issue-demo
2. dotnet build -c Release
3. dotnet publish -c Release
4. Unzip the created aab files in bin\Release\net6.0-android\publish, and find the manifest which shows a version of 1 rather than 99
5. You can also see it in the obj\Release\net6.0-android\android\AndroidManifest.xml file

The above repo was created using:

1. dotnet new android with dotnet 6 RC1 sdk
2. Then change the versionCode from 1 to 99 in the AndroidManifest.xml at the root of the repo.

No IDEs directly involved. I did it all from command line

@sfoslund I don’t know if we can transfer across Github organizations:

https://github.com/xamarin/xamarin-android/issues

@mungojam our templates put the version like this in RC 2:

<ApplicationVersion>1</ApplicationVersion>
<ApplicationDisplayVersion>1.0</ApplicationDisplayVersion>

So the same MSBuild properties can work on iOS, tvOS, etc. Docs on this here.

You could leave the versionCode and versionName values out completely in AndroidManifest.xml.

Your case still seems like it might be a bug, I’ll test this.
