@ivanpovazan do you know why these AOT tests can t find these files , its fa
"/_/src/libraries/System.Text.Json/src/System/Text/Json/Serialization/Converters/Value/EnumConverterFactory.cs",

[ivanpovazan]

The test failures seems to come from the fact that an expected build warning with NativeAOT, is not reported anymore in the build.

The expected list of warnings is defined here:

maui/src/TestUtils/src/Microsoft.Maui.IntegrationTests/Utilities/BuildWarningsUtilities.cs

Lines 129 to 148 in ed6aaaf

	private static readonly List<WarningsPerFile> expectedNativeAOTWarnings = new()
	{
	// NOTE: this one is only expected when rooting all assemblies
	new WarningsPerFile
	{
	File = "/_/src/libraries/System.Text.Json/src/System/Text/Json/Serialization/Converters/Value/EnumConverterFactory.cs",
	WarningsPerCode = new List<WarningsPerCode>
	{
	new WarningsPerCode
	{
	Code = "IL3050",
	Messages = new List<string>
	{
	"System.Text.Json.Serialization.Converters.EnumConverterFactory.CreateConverter(Type,JsonSerializerOptions): Using member 'System.Text.Json.Serialization.Converters.EnumConverterFactory.Create(Type,EnumConverterOptions,JsonNamingPolicy,JsonSerializerOptions)' which has 'RequiresDynamicCodeAttribute' can break functionality when AOT compiling. JSON serialization and deserialization might require types that cannot be statically analyzed and might need runtime code generation. Use System.Text.Json source generation for native AOT applications.",
	}
	},
	}
	},
	};

and got introduced in: 14f33bf

I suggest retrying with the empty list of warnings ie: expectedNativeAOTWarnings = new();
