歧义方法在使用泛型类型参数时重载

Consider the following program:

考虑以下项目:

using System;
using System.Threading.Tasks;

public class Program
{
    public static void Main()
    {
        var stringTask = Task.FromResult("sample");
        stringTask.TeeAsync(st => Task.CompletedTask).Wait();
    }
}

public static class FunctionalExtensions
{
    public static async Task<T> TeeAsync<T>(this T source, Func<T, Task> asyncAction)
    {       
        await Task.Delay(0); // todo: do something with source

        return source;
    }

    public static async Task<T> TeeAsync<T>(this Task<T> asyncSource, Func<T, Task> asyncAction)
    {
        var source = await asyncSource;

        await Task.Delay(0); // todo: do something with source

        return source;
    }
}
