[severity:It's more difficult to complete my work]
VBC refuses to compile this following VB console program:

Imports System

Module Program
    Sub Main()
        Dim fn As Func(Of Byte, Double) = AddressOf Double.CreateTruncating
        Dim b As Byte = 10
        Console.WriteLine(fn(b))
    End Sub
End Module

Can't compile with or without (Of Byte). AddressOf Convert.ToDouble or a wrapper lambda passes but I don't accept those as workarounds because they don't meet my need.

Environment: VS 17.14.7, vbc 4.14.0-3.25279.5 (995f12b), .Net 9.0, Windows 11 (10.0.26100.4484)
