To fix the problem, we need to remove the unnecessary assignment to the syntax
variable. This can be done by simply deleting the line where the assignment occurs. This change will not affect the existing functionality of the code.

To fix the problem, we need to remove the redundant cast from the expression attributeData.ApplicationSyntaxReference?.GetSyntax() as SyntaxNode
. This can be done by simply using the expression attributeData.ApplicationSyntaxReference?.GetSyntax()
directly, as it already returns a SyntaxNode
.
- Locate the line with the redundant cast in the file
csharp/extractor/Semmle.Extraction.CSharp/Populators/TypeContainerVisitor.cs
. - Remove the
as SyntaxNode
cast from the expression. - Ensure that the functionality remains unchanged.

Potential fix for https://github.com/krishnprakash/codeql/security/code-scanning/4
To fix the problem, we need to replace the
foreach
loop that implicitly filters its target sequence with aforeach
loop that explicitly filters the sequence using theWhere
method. This change will make the code more readable and maintainable.foreach
loop on line 28 with aforeach
loop that uses theWhere
method to filter the sequence.attributeData.ApplicationSyntaxReference?.GetSyntax() is SyntaxNode syntax
is moved to theWhere
method.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
