Had a search and can't find this.
I'm looking for the VB.Net equivalent of C#7 inline out variable declaration, e.g:
MethodCall(arg1, out string arg2);
Does such a thing exist in the equivalent VB.Net versions?
* the duplicate proposed isn't quite right I'm afraid, but I've marked Heinzi's answer correct.

The new inline variable declaration syntax allows you to declare the variable directly in a code block (allowing also multiple symbols as usual): procedure Test; begin var I: Integer; I := 22; ShowMessage (I.
An out-parameter represents information that is passed from the function back to its caller. The function accomplishes that by storing a value into that parameter. Use call by reference or call by pointer for an out-parameter. For example, the following function has two in-parameters and two out-parameters.
The out is a keyword in C# which is used for the passing the arguments to methods as a reference type. It is generally used when a method returns multiple values.
Variables passed as out arguments do not have to be initialized before being passed in a method call. However, the called method is required to assign a value before the method returns.
This feature has been suggested to the Visual Basic language team:
but it is currently not implemented.
