WithLeadingTrivia The generated code has no comments. What is the reason?

ver: Microsoft.CodeAnalysis.Analyzers.1.0.0-rc2

string mName = $"GetAssetPath_{key}";
var docComment = $"/// <summary>\n"  +
				 $"/// Path:{path}\n" +
				 $"/// <summary>\n";

var getAssetPathMethod = generator.MethodDeclaration(mName, accessibility: Accessibility.Private,returnType: generator.TypeExpression(SpecialType.System_String));
{	
	var getAPMe = generator.MemberAccessExpression(generator.ThisExpression(), nameof(GetAssetPath));

	getAssetPathMethod = generator.WithStatements(getAssetPathMethod,
		new[]
		{
			generator.ReturnStatement(generator.InvocationExpression(getAPMe, generator.LiteralExpression(key)))
		});
	
	@getAssetPathMethod = @getAssetPathMethod.WithLeadingTrivia(ParseLeadingTrivia(docComment));
}
@class = (ClassDeclarationSyntax) generator.AddMembers(@class, getAssetPathMethod);
namespaceDeclaration = (NamespaceDeclarationSyntax) generator.AddMembers(namespaceDeclaration, @class);
CompilationUnitSyntax unitSyntax = (CompilationUnitSyntax) generator.CompilationUnit(namespaceDeclaration);
unitSyntax.NormalizeWhitespace().ToFullString()

out code:

Hope the result is like this:

If you only output the method code separately, the result obtained is normal

[CyrusNajmabadi]

If you only output the method code separately, the result obtained is normal

Can you clarify what you mean by that?

[yika-aixi]

The code obtained by CompilationUnitSyntax..NormalizeWhitespace().ToFullString() has no comments, but if it is only MemberDeclarationSyntax..NormalizeWhitespace().ToFullString(), there are comments

        [Test]
        public void _testCode()
        {
            var docComment = $"/// <summary>\n"   +
                             $"/// Path:d:/test/c.png\n" +
                             $"/// <summary>\n";
            
            var workspace = new AdhocWorkspace();
            var generator = SyntaxGenerator.GetGenerator(workspace, LanguageNames.CSharp);
        
            var unit = generator.CompilationUnit();

            var method = generator.MethodDeclaration("test");

            method = method.WithLeadingTrivia(SyntaxFactory.ParseLeadingTrivia(docComment));

            var c = generator.ClassDeclaration("TestClass");
            
            c = generator.AddMembers(c, method);
            
            unit = generator.AddMembers(unit,c);

            Console.WriteLine(method.NormalizeWhitespace().ToFullString());
            Console.WriteLine(unit.NormalizeWhitespace().ToFullString());
        }

My English is not very good. The comments are lost when adding documentation notes to methods and then adding them to the class to output the code of the class

[CyrusNajmabadi]

No worries about hte english. Thanks for the clarification. Your examples work properly for me:

I get:

/// <summary>
/// Path:d:/test/c.png
/// <summary>
void test()
{
}

And:

class TestClass
{
    /// <summary>
    /// Path:d:/test/c.png
    /// <summary>
    void test()
    {
    }
}

Maybe you're on a version of roslyn with a bug?

[yika-aixi]

I upgraded the version to see, maybe my version is too old, thank you

[yika-aixi]

I upgraded to the latest version and there is no problem
