• Can you please attach a, small, self contained example (source+configuration file in a, compressed, tar or zip file) that allows us to reproduce the problem? Please don't add external links as they might not be persistent.
• Please also specify the full doxygen version used (doxygen -v). (Just 1.9.8 is not sufficient as it is currently the master version and thus a moving target)

doxygen -v = 1.9.8 (0ea6a23)
doxygen-record-example.tar.gz

In project there are two files Class and Record.

But when doxygen is generated it shows only class but no record.

It looks like record class and record struct do work (by accident?).
From https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/record:

Beginning with C# 9, you use the record keyword to define a reference type that provides built-in functionality for encapsulating data. C# 10 allows the record class syntax as a synonym to clarify a reference type, and record struct to define a value type with similar functionality.

So looks like:

• record should properly be recognized for class and struct as well
• in case of just record this should be treated as record class.

I tried record class but it doesn't work neither. Hope you'll make it the future.

The following did work for me (it shows the Point_class and the Point_struct, the Point_bare is a problem as indicated before):
aa.cs

public record struct Point_struct
{
    public double X_struct { get; set; }
}
public record class Point_class
{
    public double X_class { get; set; }
}
public record Point_bare
{
    public double X { get; set; }_bare
}

Doxyfile

QUIET = YES
EXTRACT_ALL = YES

Example: example.tar.gz

Found that it works only for record class that initialized with curly braces.

public record class TestRecord1
{
	public int A;
	public int B;
};

public record class TestRecord2(int A, int B);

Thanks for the extra info, the public record class TestRecord2(int A, int B); is seen as a function prototype:

Glad we found the problem, waiting for update!
