CallerMemberName should work on target typed new() #49547
Description
Description
CallerMemberNameAttribute is not working correctly with the new target typing feature.
The caller should be the same regardless of target typing. However, the attribute is currently not being respected when target typing new(). The program below demonstrates.
using System;
using System.Runtime.CompilerServices;
namespace ConsoleApp2
{
class Foo
{
public string Caller { get; set; }
public Foo([CallerMemberName] string caller = "?") => Caller = caller;
public void PrintCaller() => Console.WriteLine(Caller);
}
class Program
{
static void Main()
{
Foo f1 = new Foo(); // Explicit typing
f1.PrintCaller(); // Prints "Main"
Foo f2 = new(); // Target typing
f2.PrintCaller(); // Prints "?"
Console.WriteLine("\n\nPress any key...");
_ = Console.ReadKey(intercept: true);
}
}
}
Configuration
