Workload net6.0-android is out of support (Error)

1

Today I created a Android phone game in project in Visual Studio Community 2022 Version 17.8.1. After the blank project was created I compiled the code and am now receiving these two error messages.

The workload ‘net6.0-android’ is out of support and will not receive security updates in the future. Please refer to .NET MAUI official support policy | .NET for more information about the support policy.

SupportedOSPlatformVersion 23 cannot be higher than TargetPlatformVersion 21.0. AndroidProjectMonoGame

I can’t figure out how to fix this issue. Note that I installed Monogame about 11 months ago, so I don’t know if I need to update my Monogame code.

I do have the latest version of Visual Studio. Anyway, can someone help me out please?

After the release of .net8 on september, the .net6 targets for ex-xamarin platforms (android, ios) got deprecated.

Open the .csproj and change targetframework from net6-android to net8-android.
Then open the manifest .xml and change the minSdkFramework (or something similar) minSdkVersion
from 17,19 or whatever it was… to 21.

Wow, I appreciate the help. I made the changes, and now I am getting an error message about the Java SDK. Do I need to download and install it?

Here is the error message:
XA5300 The Java SDK directory could not be found. Install the Java SDK by by following the instructions at : "Setting up the Android SDK for Xamarin.Android - Xamarin | Microsoft Learn.

I don’t know about that.

Check if you have the ‘MAUI - Xamarin’ workload installed in VS22.

Could you introduce your method in detail?I can no longer run the project aafter manually changing targetframework from net6.0-android to net8.0-android,and I can not find the “minSdkFramework” item in manifest.xml.

I wrote the first out of memory, because I was on a phone at the time, so I got some names wrong.

Here is a commit with the changes to upgrade the project to .net8.

In your .csproj file:

  • replace ‘net6.0-android’ with ‘net8.0-android’ in “TargetFramework” tag.
  • remove “SupportedOSPlatformVersion” tag. (or upgrade the value according to the error messages)

In your AndroidManifest.xml file:

  • remove “uses-sdk” tag. (or upgrade the values of minSdkVersion and targetSdkVersion according to the error messages)

The default values of “SupportedOSPlatformVersion” and “uses-sdk” tags will do just fine for most cases and you don’t really need them. The app will be build with the least supported sdk version as minSdkVersion/SupportedOSPlatformVersion and the last installed sdk as the targetSdkVersion.

nkast,I appreciate the help. The emulator displays briefly then closes. See my screenshot. I removed the lines you suggested, in the diagram I drew a red line
threw them to show you the lines I deleted. Any ideas why the emulator is crashing? When you have time, thanks.

Thank you!
I’ve been failing to compile my game for about a week now.
Now it compiles correctly!

That also got rid of the errors for my Android project!
But now when I deploy to the emulator, nothing happens, VS Studio just says “Build succeeded” and the app is never transferred to the emulator?
Also if I plug in my Android device, it’s usually appears in the drop-down list, but does not anymore?

It’s worth mentioning I can open Android Studio and deploy all my old projects to my phone without trouble.

Any ideas?
