I'm getting the error of the tittle when trying to use XCT TabView.

I'm using Microsoft Visual Studio Community 2022. I installed XCT in my project by running both the commands in NuGet Package Manager Console:

Install-Package Xamarin.CommunityToolkit

Install-Package Xamarin.CommunityToolkit.Markup

In NuGet solution manager I selected both packages, I checked every checkbook responding to my projects and I hit "Install".

I get the following errors and warnings though:

Package restore failed. Rolling back package changes for 'MyProject'.

and

Error NU1605 Detected package downgrade: Xamarin.Forms from 5.0.0.2291 to 5.0.0.2196. Reference the package directly from the project to select a different version.
MyProject -> Xamarin.CommunityToolkit.Markup 2.0.0 -> Xamarin.Forms (>= 5.0.0.2291)
MyProject -> Xamarin.Forms (>= 5.0.0.2196)

I also added the relative namespace to XAML: xmlns:xct="http://xamarin.com/schemas/2020/toolkit

By the way, I get the same error too for xct:TabViewItem but I additionally get another error for it: Cannot resolve type "xct:TabViewItem"

Any ideas?

I had tried to do this and met the same problem as you.

This issue happened because the version of xamarin.forms is too low. So you can open the nuget package manager to update the xamarin.forms to the lastest version.

You can also download the earlier version of the Xamarin.CommunityToolkit and Xamarin.CommunityToolkit.Markup such as 1.3.1
