Hi all I migrated functional project Xamarin to maui via utility "upgrade-assistant upgrade" generated good 👍. But when I run/compile it, I got: Error NETSDK1045 The current .NET SDK does not support targeting .NET 11.0. Either target .NET 8.0 or lower, or use a version of the .NET SDK that supports .NET 11.0. Download the .NET SDK from https://aka.ms/dotnet/download in file: \Microsoft.NET.TargetFrameworkInference.targets 166 if I change value <TargetFrameworkVersion>v12.0</TargetFrameworkVersion> in file .Android.csproj.user I got: Error NETSDK1045 The current .NET SDK does not support targeting .NET 12.0. Either target .NET 8.0... What should I setup please? Thanks and best regards!

NET 8 is the latest LTS release and NET 9, which has just started development, is the latest CTS. There is no NET 11/12 release to target. Not sure why your target framework was set to this value. Irrelevant this is the old property for NET Framework apps. Your MAUI app shouldn't even have that property. Remove the TargetFrameworkVersion property and replace it with <TargetFrameorks>net8.0-android;net8.0-ios;net8.0-maccatalyst</TargetFrameworks> . This targets Android, iOS and Mac for NET 8. Alternatively create a new MAUI project temporarily and copy the TargetFrameworks properties from the project file as there are several that you might need, one is conditional.

Hi Michael Thanks for reaction! if I put your "net8.0-android;net8.0-ios;net8.0-maccatalyst" and I will get numeric parsing error (see picture)

<?xml version="1.0" encoding="utf-8"?> <Project ToolsVersion="Current" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <SelectedDevice>pixel_5_-_a11-api_30</SelectedDevice> <SelectedPlatformGroup>Emulator</SelectedPlatformGroup> <ActiveDebugProfile>Pixel 5 - A11- API 30 %28Android 11.0 - API 30%29</ActiveDebugProfile> <DefaultDevice>pixel_5-_a11-_api_30</DefaultDevice> <AndroidDesignerPreferredTheme>MainTheme</AndroidDesignerPreferredTheme> <ProjectView>ShowAllFiles</ProjectView> <TargetFrameworkVersion>v11.0</TargetFrameworkVersion> </PropertyGroup> </Project> I don't know why system combine .NET version vs Android version... or what I do wrong? XYZ.Android.csproj (probably is correct): "<TargetFrameworks>net8.0-android30.0</TargetFrameworks>" main XYZ.csproj (probably is correct): <TargetFrameworks>net8.0-ios;net8.0-android;net8.0</TargetFrameworks> <TargetFrameworks Condition="$([MSBuild]::IsOSPlatform('windows'))">$(TargetFrameworks);net8.0</TargetFrameworks> thanks

Problem is (maybe) file XYZ.Android.csproj.user: (TargetFrameworkVersion v11.0 or v12.0 is Android version, not .NET version)

I don't know why system combine .NET version vs Android version... or what I do wrong? regards

Sorry, I didn't catch the .user on your OP. The .user file is a per-user generated file that is created to store your per-user settings, like breakpoints. Delete the file and try building again. This file isn't part of source control so blowing it away is equivalent to you retrieving and building the project the first time. You probably want to do a rebuild solution as well.

Hi Michael thanks!, I deleted file XYZ.Android.csproj.user and no NETSDK1045 error anymore, but I have a new error :-): NETSDK1181 Error getting pack version: Pack 'Microsoft.Android.Ref.30' was not present in workload manifests. Should you also have a some advice? thanks in advance! W

This isn't my area of expertise but check your TargetFrameworks property in the project file. Specifically look at the version of net8.0-android???. I think they need to match.
