ConsoleApp sample server generates an exception with .NET 8.0 about h.pipes

I looked a little more into MessagePack, and it requires marking all types/properties with attributes, which is not entirely appropriate for Formatter by default.

[MessagePackObject]
public class MyClass
{
    // Key attributes take a serialization index (or string name)
    // The values must be unique and versioning has to be considered as well.
    // Keys are described in later sections in more detail.
    [Key(0)]
    public int Age { get; set; }

    [Key(1)]
    public string FirstName { get; set; }

    [Key(2)]
    public string LastName { get; set; }

    // All fields or properties that should not be serialized must be annotated with [IgnoreMember].
    [IgnoreMember]
    public string FullName { get { return FirstName + LastName; } }
}

So I changed this to SystemTextJsonFormatter for net8.0 and above

Great, thanks for looking into this problem so quickly.

Now it's available in latest dev/preview version, I will release this as stable little later.
