xml linq c# namespaces dotnet-core C#

I've looked through the documentation and I'm still confused about I'm integrating two systems and I can't seem to get I am working with LINQ to XML in C# and am experiencing issues when querying XML documents that contain namespaces. I have an XML file that looks like this: ```xml <root xmlns:ns="http://example.com/ns"> <ns:item id="1">Item 1</ns:item> <ns:item id="2">Item 2</ns:item> </root> ``` When I try to fetch items using the following LINQ query: ```csharp XDocument doc = XDocument.Load("path/to/your/file.xml"); var items = from item in doc.Descendants("item") select item; ``` The `items` variable ends up being empty, which is not what I expected. I also tried specifying the namespace explicitly like this: ```csharp XNamespace ns = "http://example.com/ns"; var itemsWithNamespace = from item in doc.Descendants(ns + "item") select item; ``` However, when I run this code, I get an empty enumerable. I verified that the XML file is correctly formatted and accessible. I also tried using `doc.Root.Elements(ns + "item")`, which still returns no elements. The LINQ to XML queries work fine with non-namespaced XML. Could this be a version-specific scenario with LINQ to XML in .NET Core 3.1? I am using the latest update with Visual Studio 2019. Any help on how to correctly handle these namespaces would be greatly appreciated! I'm working with C# in a Docker container on Ubuntu 20.04. This is for a REST API running on Debian. This issue appeared after updating to C# LTS. Has anyone dealt with something similar?
