Activity trigger doesn't support ValueTuple parameter

[Bouke]

Description

In order to pass multiple parameters to an activity trigger, it was suggested in the past to use a ValueTuple. However I've found that this doesn't work as JsonSerializer [doesn't support (de)serialising ValueTuple by default][0].

Expected behaviour

Passing ValueTuple as parameters should work.

Actual behaviour

Values are deserialised as null.

Relevant source code snippets

[Function("SayHello")]
public static string SayHello([ActivityTrigger] (string First, string Last) name)
{
    return $"Hello {name.First} {name.Last}!";
}

Known workarounds

• Configure JsonSerializerOptions.IncludeFields = true
• Use record parameters instead
