Swtich does not support string constants?

[zms9110750]

foreach (var ele in XElement.Load("D:\\temp.xml").Nodes())
{
	switch (ele)
	{
		case XElement xel:
			const string br = "br";
			Console.WriteLine(xel.Name switch
			{
				"br" => "\n", //CS0150
				br => "\n",	  //CS0150
				S.br => "\n", //CS0150
			});
			break;

		case XText txt:
			Console.WriteLine(txt);
			break;
	}
}
static class S
{
	public const string br = "br";
}

Why does pattern matching not treat strings as constants

[CyrusNajmabadi]

Problem here is that xel.Name is an XName, which will never match any of those. use something like xel.Name.LocalName. THen all three are supported. I agree this message is confusing. @jaredpar to see if we can improve this here.
