VB -> C#: missing type declaration in c# for vb implicitly-typed array

[KunzeAndreas]

Input code

WithList({Sub() Debug.Print("a"), Sub() Debug.Print("b")})
Private Shared Sub WithList(actions As List(Of Action))
        Debug.Print(actions.Count.ToString)
End Sub

Erroneous output

WithList(new[] { () => Debug.Print("a"), () => Debug.Print("b") }); 
--> No best type found for implicitly-typed array

Expected output

WithList(new List<Action>() { () => Debug.Print("a"), () => Debug.Print("b") });

• Did you see it working in a previous version, which? no

Thanks for this. There's already some code for inferring delegate types on the converter. Hopefully it'll be a good start for solving this. We'll need to check the VB behaviour though, often it just infers object for cases like these.

I've confirmed with an example here that "Action" can be inferred in this case

Note: It chooses whatever the target type is, so no clever lambda analysis is needed here
