Hello,

    <muxc:TabView HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
        <muxc:TabViewItem Header="Home" IsClosable="False">
            <muxc:TabViewItem.IconSource>
                <muxc:SymbolIconSource Symbol="Home" />

Hey @ilira987,

thank you for your question. When you are using the latest Uno versions, you need to use the standard TabView.

<TabView HorizontalAlignment="Stretch"
              VerticalAlignment="Stretch">
    <TabViewItem Header="Home"
                      IsClosable="False">
        <TabViewItem.IconSource>
            <SymbolIconSource Symbol="Home" />
        </TabViewItem.IconSource>
    </TabViewItem>
    <TabViewItem Header="Doc-1">
        <TabViewItem.IconSource>
            <SymbolIconSource Symbol="Document" />
        </TabViewItem.IconSource>
    </TabViewItem>
    <TabViewItem Header="Doc-2">
        <TabViewItem.IconSource>
            <SymbolIconSource Symbol="Document" />
        </TabViewItem.IconSource>
    </TabViewItem>
    <TabViewItem Header="Doc-3">
        <TabViewItem.IconSource>
            <SymbolIconSource Symbol="Document" />
        </TabViewItem.IconSource>
    </TabViewItem>
</TabView>

Interesting! Are you using the Recommended template with Material? Here is my project with Fluent:
TabViewAndroid.zip. Let me know if this one works for you. I will take a look into more details after.

I checked TabViews szenario with different templates - with and without Material also, Used with other templates (Uno Platform App (.Net 6, UWP), does not run, where Uno.UI is used (actually I prefer this variant)
TabView uno runs on me only with much older uno versions (like WinUI 5.3.144).

Hello @morning4coffe-dev ,

found a solution, the problem was in the uno.sdk version in global.json - it was 5.5.62, updated to 5,6,20, it's ok now.

Best regards.

@ilira987 Thank you for the info! I was just looking into the recent fixes on TabView and it seem to have been resolved by 0e5f8fe. Still interesting why it worked on my side.
