Implicit argument conversions for some types

[robertcoltheart]

Hi,

How hard would it be to have argument conversions for some types?

The use case I'm thinking of is having a DateTime parameter and passing in a string, since DateTime cannot be used as an argument. There might be other cases but this is just something I ran into today.

[Test]
[Arguments("2025-12-05")]
public Task CanConvert(DateTime date)
{
}

Or is this a complete non-starter because of source generation? Of course the alternative is to just use method data sources.
