[Youssef1313]

Is there an existing issue for this?

Current Behavior

Maui.Markup/src/CommunityToolkit.Maui.Markup.SourceGenerators/SourceGenerators/TextAlignmentExtensionsGenerator.cs

Lines 22 to 61 in cf4b8e3

	var userGeneratedClassesProvider = context.SyntaxProvider.CreateSyntaxProvider(
	static (syntaxNode, cancellationToken) => syntaxNode is ClassDeclarationSyntax { BaseList: not null },
	static (context, cancellationToken) =>
	{
	var compilation = context.SemanticModel.Compilation;
	var iTextAlignmentInterfaceSymbol = compilation.GetTypeByMetadataName(iTextAlignmentInterface);
	if (iTextAlignmentInterfaceSymbol is null)
	{
	throw new Exception("There's no .NET MAUI referenced in the project.");
	}
	var classSymbol = (INamedTypeSymbol?)context.SemanticModel.GetDeclaredSymbol(context.Node);
	// If the ClassDlecarationSyntax doesn't implements those interfaces we just return null
	if (classSymbol?.AllInterfaces.Contains(iTextAlignmentInterfaceSymbol, SymbolEqualityComparer.Default) is not true)
	{
	return null;
	}
	return classSymbol;
	});
	// Get Microsoft.Maui.Controls Symbols that implements the desired interfaces
	var mauiControlsAssemblySymbolProvider = context.CompilationProvider.Select(
	static (compilation, token) =>
	{
	var iTextAlignmentInterfaceSymbol = compilation.GetTypeByMetadataName(iTextAlignmentInterface);
	if (iTextAlignmentInterfaceSymbol is null)
	{
	throw new Exception("There's no .NET MAUI referenced in the project.");
	}
	var mauiAssembly = compilation.SourceModule.ReferencedAssemblySymbols.Single(q => q.Name == mauiControlsAssembly);
	var symbols = GetMauiInterfaceImplementors(mauiAssembly, iTextAlignmentInterfaceSymbol).Where(static x => x is not null);
	return symbols;
	});

Expected Behavior

Better pipeline
