How to configure android packagename within Maui android project?

I have created a dummy maui app. I managed to get the package name with the following code after following App information
#page "/"
<h1>Hello, world!</h1>
Welcome to your new app.
<SurveyPrompt Title="How is Blazor working for you?" />
<ul>
<li>Name: #name</li>
<li>Package: #package</li>
<li>Version: #version</li>
<li>Build: #build</li>
</ul>
#code {
private string name = AppInfo.Current.Name;
private string package = AppInfo.Current.PackageName;
private string version = AppInfo.Current.VersionString;
private string build = AppInfo.Current.BuildString;
protected override async Task OnInitializedAsync()
{
}
}
As you can see from the following image this does work it displays my android application information. but ...
My question is how to configure this Package name shows as com.companyname.blazortest. I would like to be able to supply my company name
There is no appsettings.json file, its not in the AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<application android:allowBackup="true" android:icon="#mipmap/appicon" android:roundIcon="#mipmap/appicon_round" android:supportsRtl="true"></application>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
Im a bit stumped as to where this is configured.

You can change it manually in your .csproj file
<!-- App Identifier -->
<ApplicationId>com.companyname.app.maui</ApplicationId>
or you can change it in project properties
or if you want to change it in android project only you can do it under Android section (it will change your manifest file)

Is my Universal Windows Platform software able to gain the permission that is necessary for initiation of shutdown?

I am desiring addition to my Universal Windows Platform software the ability for it to shut-down its host machine after invocation of it by 1 button-click, however, 0 methods that I have tried thus far have operated:
I have attempted to instruct Windows to shut-down, but shutdown /s /t 120 is not able to operate, specifically after invocation by my application.
Therefore, I attempted uage of native C# code. However, usage of this has informed me that it has not been permitted to invoke shutdown:
ShutdownManager.BeginShutdown(Windows.System.ShutdownKind.Shutdown, TimeSpan.FromSeconds(120));
I have used many methods, but I am not able to remediate this problem.

Please do note that I am wanting to use this command on Windows 10, rather than Windows 10 IoT; I merely am attempting to use those commands because they are the only other way I have been able to conceive of invocation of this without reliance upon either PowerShell, Python or the Windows Command Processor.

According to the description of ShowdownManager, it needs the support of IOT SDK, which means it is a platform-limited API (only valid on IOT devices).
In Windows 10 desktop devices, UWP does not have the permission to turn off the device.

Xamarin.Android Firebase.Messaging - D/FirebaseInstanceId(13164): background sync failed: INVALID_SENDER

I am adding push notifications to a Xamarin app in development.
After following guides I've done everything that should allow it to work.
google-services.json downloaded from firebase, added to project and build action set to GoogleServicesJson
play services is available as confirmed in a check
receiver node added to AndroidManifest.xml
FirebaseIIDService implemented
Notification channel is created
mainfest receiver code:
<application android:label="RMS Metro Calendar">
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="${applicationId}" />
</intent-filter>
</receiver>
</application>
FirebaseIID code (I'm not implementing registration management on the server side):
[Service]
[IntentFilter(new[] { "com.google.firebase.INSTANCE_ID_EVENT" })]
public class MyFirebaseIIDService : FirebaseInstanceIdService
{
const string TAG = "MyFirebaseIIDService";
public override void OnTokenRefresh()
{
var refreshedToken = FirebaseInstanceId.Instance.Token;
Log.Debug(TAG, "Refreshed token: " + refreshedToken);
SendRegistrationToServer(refreshedToken);
}
void SendRegistrationToServer(string token)
{
// Add custom implementation, as needed.
}
}
The app builds and deploys fine, I can sucessfully log out that Play services is available and in logging I get: FirebaseApp initialization successful
However it does not generate a Firebase instance and no Instance.Token is ever received. All I get is the following logging message:
09-19 13:48:31.576 D/FirebaseInstanceId(18578): background sync
failed: INVALID_SENDER, retry in 10s
from which is continues to retry in ever growing time scales.
I'm sure there must be something I've configured incorrectly somewhere with regards to the receiver/IID service implementation, but for the life of me cannot figure it out.
Has anyone else ever come across this? Is there a way I can test the FCM service for my configuration to get back more information on why it is failing?
Thank you!

Problem with Xamarin autostart application

I am currently developing an app to use a barcode scanner, one of the requirements is that app autostart with the device.
so, google on that I found some interest thinks, but when I implemented it fails epicly, the app does not starts.
this is mainfest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="AppConsulta.Droid" android:versionCode="1" android:versionName="1.0" android:installLocation="auto">
<uses-sdk android:minSdkVersion="23" android:targetSdkVersion="24" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<application android:label="AppConsulta.Android" android:icon="#drawable/Logo_Jumbo_Cencosud">
<activity android:name="MainActivity" />
<receiver android:name=".BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
and this is my receiver
namespace AppConsulta.Droid
{
[BroadcastReceiver]
[IntentFilter(new[] { Intent.ActionBootCompleted }, Priority = (int)IntentFilterPriority.LowPriority)]
public class BootReceiver : BroadcastReceiver
{
public override void OnReceive(Context context, Intent intent)
{
Intent serviceStart = new Intent(context, typeof(MainActivity));
serviceStart.AddFlags(ActivityFlags.NewTask);
context.StartActivity(serviceStart);
}
}
}
using adb.exe I manage to extract the log of the device
and it shows this

Xamarin Maps Crashing in Android Emulator

I'm having a bit of an issue with the Xamarin.Forms.Maps and the exceptions are not propagated up into the debugger in a meaningful way to help me diagnose the issue.
I can get it to work, everytime I reinstall Visual Studio. It will work a couple times then eventually it will crash 100% of the time as long as the Map item is in the xaml. I am not remaking the project between running, just reinstalling Visual Studio. I'm running Visual Studio 17 Community.
The error just says:
'Your app has entered a break state, but there is no code to show because all threads were executing external code (typically system or framework code).'
I have a valid API Key, and even if I comment out ALL code relating to the Map it eventually happens other than the Xaml that will create it. If I reinstall visual studio I can manipulate the map the first few times I invoke the debugger before it fails.
I wish I could give more information, but I'm pretty new to Xamarin development so I'm a bit unsure why reinstalling Visual Studio fixes the issue, temporarily. Any insight would be much appreciated, as I've spent many hours trying to diagnose and reinstall, but have no idea what the issue could be given the error doesn't really say much of anything. I'd love to provide more information if someone has more ideas for me to check out.
In general, it also fails to deploy eventually also : / which is why I tried an install originally. I'm not sure if this is related.
