nuget version has nothing to do with extension. just open your csproj file and edit every version related to Avalonia to 11.0.10.

commented

And using nuget manager you can choose the version here

Please don't open bug reports for questions. Use discussions instead. Will convert this one later when I have time to.

commented

When I say every, I mean every. Your desktop, android, ios and browser project is still 11.0.2

Also the VS package manager is a real pain to use with a large dependency chain like Avalonia (it often complains about transient conflicts which forces you to upgrade things in a specific order). It's easier to just manually upgrade everything by editing your project file. You should be able to upgrade all packages fairly easily though by checking the box on the updates tab.

@rabbitism do you see below error?

commented

@thevortexcloud may i know how to edit project file

commented

If you are using a project using the new SDK format (which you likely are if you have made a new project), you can double click the project in the solution explorer. If you are using the old format, you need to unload the project and then right click it, and press edit. Or you can just open it directly with an external text editor.

You may also need to trigger a restore. Try running dotnet restore in a terminal while inside your project directory. While you are there, also run dotnet new update to update your Avalonia templates. If it still does not work after all that, then you should be able to create a new solution using the latest templates.

In case of android project, you will also need to change the TargetFramework to net7.0-android.

commented

may i know how to change TargetFramework to net7.0-android.

target framework: 7.0, rebuild solution, error

target framework: 6.0, rebuild solution, error

I suggest reading the official .NET docs and watching/reading a few tutorials. Most of this has nothing directly to do with Avalonia.

https://learn.microsoft.com/en-us/dotnet/core/project-sdk/overview
https://learn.microsoft.com/en-us/dotnet/standard/frameworks

Anyway, you should not have android/iOS package references in a project that does not target the correct TFM.

commented

You have mixed Desktop, iOS and Android package. Single project is experimetal feature.

You should use following comnand to create new Cross platform project from template

dotnet new avalonia.xplat  -n MyApp

or select Cross Platform Application template.

After creation. You have more project, each for plat (MyApp.Android.cspoj, ...).

The Cross plat xaml and code should put into MyApp.csproj

Add DataGrid package to MyApp.csproj

Rebuild the solution

Edit app.axaml and add DataGrid Style
