"Manifest parsing has failed" when installing teams apps from App Studio - microsoft-teams

I haven't been able to install any applications I create using App Studio since yesterday afternoon (Oct 5 Us/New_York time). When I try to install directly from App Studios I get a "Manifest parsing has failed" error message. If I download the package and try to upload it to the team I get a generic something went wrong error message.
Im having this issue with all my applications including those I haven't made any changes to.
I am running Microsoft Teams Version 1.3.00.24758 and App Studio version Version 1.5.1
App studios is setting the manifest's to version 1.8
I have the same issue when I run teams in developer preview.
On a side note: I notice that App Studio now has the option to create a Team tab for a Meeting. Which I believe is in preview right now and not officially out. I don't remember seeing that earlier in the day. Maybe App Studio was recently updated?

Xamarin Form Won't Deploy Visual Studio 2019

I'm new to creating Mobile Android apps using Visual Studio and I've started creating a new Xamarin Forms project. I didn't add any code. I just created it and testing out how it works. When I tried to deploy, it will show an error, "There were deployment errors. Continue?"
Deployment Error
I even went to the Android Device Manager to create an Android Emulator and it also provided me this error.

I tried every solution that I could find online. Some told me to rebuild, clean and build my solution. That didn't work. I researched to check mark Hyper-V in the Windows features and even rebooting my computer several times and that didn't work. When I tried to deploy, this shows up in the output log. Not sure if this will help.

I also attached images of what I've done so far and I really don't know what else to do.

App Studio is auto-converting my app to Schema 1.9, and the failing to install it into Teams

I'm uploading an app manifest into App Studio that's an older version (happens to be 1.5), but when I try Install it using App Studio, it fails. When I go to the schema editor inside App Studio, it shows me it's changed it to Schema Version 1.9, which I think is the issue.
Incidentally, this user is having a similar-but-different issue: App Studio is generating a version 1.9 manifest which fails validation and stops side loading earlier today.
We are able to repro the issue. Raised a bug. We don't have ETA to share when it will be fixed.

Share xamarin app with friend for testing

thanks in advance. I've been working on a Xamarin app that I hope to market before too long. It's at the stage where I'd like to share it with one or 2 beta testers on Windows 10. however, I am unable to run the app outside of Visual Studio (where it works fine). When I try to click on the relevant debug or release .exe in Windows Explorer nothing happens. How can I let my beta testers try it without having them install VS and giving them the entire project?
If you have registered a Microsoft developer account and paid for it, then you can add your tester's Microsoft account to the console, then you upload your app to the console, they can see it in the store for testing.
Otherwise, you can make an offline bundle file using the visual studio publish wizard. For more info, see the details.

Xamarin: publish iOS to App Store from Visual Studio no working

I'm actively using Visual Studio 16.6 windows / 8.6.1 macOS to build and test iOS / Android application, in Xamarin Forms. macOS is running Xcode 11.
I can't push to AppStoreConnect from "Sign and Distribute" directly.
Everything is working fine step by step: build in release for iDevice, signing and distribution profile accepted, export to IPA file, and uploading via Xcode->Organizer. But i'd like to do this simply from Visual Studio; either on my PC or mac.
I have the following errors on Visual Studio / windows when uploading to AppStoreConnect:
Error: unable to create IPA file for distribution of archive myApp
MessagingRemoteException: error happened on client Build160001055 during execution of an answer for category xvs/Build/16.6.0.1055/execute-task/myApp.iOS/c1cf1c8002fCopy
TypeInitializationException: The type initializer for 'Microsoft.Build.Tasks.Copy' threw an exception.
PlatformNotSupportedException: Operation is not supported on this platform.
I have the following error on Visual Studio / macOS when uploading to AppStoreConnect:
Publication failure: we are unable to create an authentification session.
Notice Visual Studio / macOS is asking creds (i'm using developper account) while Visual Studio / windows is not (i surely have it registered before, but i don't remember).
This issue appears to have been resolved in a hotfix (16.6.1) released today, as per this bug report: https://developercommunity.visualstudio.com/content/problem/961282/xamarinios-fails-to-build-with-messagingremoteexce.html

Multiple errors when creating Xamarin.Forms - Blank Xaml App (Xamarin.Forms Portable) or Android App

I using Windows 10 and am trying to create a Xamarin.Forms - Blank Xaml App (Xamarin.Forms Portable) project for the first time. I have Visual Studio 2015 Enterprise Update 3 installed and have tried uninstalling, reinstalling, and repairing multiple times.
When I create a project, I get the following errors:
"The name 'InitializeComponent' does not exist in the current context"
"Error encountered while loading the project. Some project features, such as full solution analysis for the failed project and projects that depend on it, have been disabled" - for App, Droid, UWP, WinPhone, Windows, and iOS
"The XamlCTask task failed unexpectedly..." - for UWP, WinPhone, Windows, and iOS
I tried this on my work computer and home computer and I had the same issues with both.
I have tried updating Xamarin.Forms nuget to the latest version and the created 36 errors with Droid. I also tried going to c:/users/[YOURNAME]/AppData/Local. Delete the Xamarin folder and that did not solve the issue.
I tried creating other Visual Studio projects that did not involve Xamarin and did not have any issues with those. I know the issue is with Xamarin (probably something with Android) itself, but I don't think that there is anything that I am missing from the install. I tried installing it by first installing Visual Studio, then going to Modify and adding Cross Platform. That didn't work, so I uninstalled then downloaded the Xamarin Installer. I had the same issues with both.
I created a blank Android App and that give me the warning - "aapt.exe" exited with code - 1073741849".
A blank app for iPhone does not give any errors or warnings.
Windows Phone does not give any errors or warnings either.
Any ideas of what I should check for so I can get this working?
Here is a picture of the error that I'm getting
Try updating to the latest version of Forms to get rid of the XamlC errors. Assuming you haven't updated, the template is using a modestly old version. As for the aapt error, if you have the N SDK preview installed, removing that should help. Alternatively, make certain that you have up through API 23 installed.
