Documentation Block without XML (Missing from Spec)

[spiritedsnowcat]

Summary
Alternative method of documentation without XML wasn't specified in the new C# spec, but exists in old spec and the current F# spec (which is still online and can be linked to). This documentation style works in Visual Studio Code's Intellisense, but not Visual Studio's Intellisense.

Spec:

The following example shows the alternative method, without XML tags. In this example, the entire text in the comment is considered a summary. Note that if you do not specify a summary tag explicitly, you should not specify other tags, such as param or returns tags.

Expected
Documentation on alternative method of documentation.
Example of working code (recognized in Intellisense).

/// Adds two numbers using thread safety
public static int Add(int a, int b) {
	return Interlocked.Add(a, b);
}

Actual
Documentation not available, and method not supported by Visual Studio's Intellisense.

What old spec are you talking about? Can you link to it?

Just because F# does it this way, doesn't mean it will work in C# too. And since it's not actually working in VS, I think this not just about correcting the spec, it's about adding a new feature.

While this may not actually be a spec correction, I do think that it would be a valuable thing to add (or re-add?) in general.

Not moving to dotnet/csharpstandard, as this isn't part of the current standard, but a request for an update.
