Fixes: #9422 Context: https://github.com/dotnet/maui/blob/51df629f946122945cee8f57baed80eb48e45c4e/src/Controls/src/Core/Properties/AssemblyInfo.cs#L79 In `Microsoft.Maui.Core.dll`, the default `x` namespace is defined as: [assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2009/xaml", "System", AssemblyName = "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")] The problem being that in apps on iOS and Android where `PublishTrimmed` is `true`, `mscorlib.dll` will get trimmed away and callsites will use `System.Private.CoreLib.dll` instead. This is very much related to the issue fixed in 880ce09. Unfortunately, my fix wasn't sufficient, because the `AssemblyName` name in this case is the full name: AssemblyName = "mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" To solve the issue, let's also check for `StartsWith("mscorlib,")`. We *could* add a new `XmlnsDefinition`, but this doesn't feel right: [assembly: XmlnsDefinition("http://schemas.microsoft.com/winfx/2009/xaml", "System", AssemblyName = "System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")] It doesn't make sense for a "private" assembly to appear in XAML intellisense. I also moved these tests to a new `XamlTests` class, as it didn't really make sense to put them with `RadioButton` tests. Note that these new tests wouldn't fail until we start running device tests in `Release` mode: #14392
