How to read values from a .csproj XML file in C#
When using XDocument to read .csproj files, you need to include the MSBuild namespace http://schemas.microsoft.com/developer/msbuild/2003 to obtain elements such as TargetFramework and PackageReference.

How to use XPath to query XML data? (Advanced Techniques)

How to update a value in an XML file programmatically
The answer is to use the XML library built into the programming language to implement the update: first load the XML file, then locate the target element or attribute and modify its value, and finally save the file. For example, Python uses ElementTree to parse, search and write back; C# uses XmlDocument combined with XPath to locate and save; Java uses a DOM parser to modify the content and then output it through a Transformer, all following the load-edit-save process.
