Call a method inside a Task.Run and return the value

[Mc_Topaz]

I have a method Bar. Bar take some arbitrary amount of time to complete. I want to call Bar from a method Foo. Foo run some code sync and last run Bar async. Bar returns a value and I want Foo to return the same value. Here is the code to reproduce the behavior:

Module Module1

Sub Main()
    Dim i As Integer = Foo()
    Console.Write("Enter anything: ")
    Console.ReadLine()
    Console.WriteLine(i)
End Sub

Async Function Foo() As Task(Of Integer)
    Console.WriteLine("Do something sync")
    Console.WriteLine("Do something sync")
    Return Await Task.Run(Function() Bar())
End Function

Function Bar() As Integer
    Console.WriteLine("Bar Start")
    Threading.Thread.Sleep(2000)
    Console.WriteLine("Bar Stop")
    Return 5
End Function

End Module

But I get a compile error in the Main method:

Dim i As Integer = Foo()

Value of type Task(Of Integer) cannot be converted to Integer. I understand the error, but I don't understand how I should solve it. I tried this line:

Dim i As Integer = Foo().Result

Which compiles and runs. But the call to the Bar method ran sync, not async. How should I alter the code to run Bar async and from Foo only return the value from Bar?

You do not make direct calls to Async functions, but call them via Await, as described in Asynchronous Programming with Async and Await - Visual Basic | Microsoft Docs[^].

In C#, it would be. var something = await Foo(); int i = something.Result; in this case "var", is the same as Task at compile time.
