Question

I am simply trying to execute an otherwise blocking method asynchronously in one line in VB.

Dim action As New Action(Sub() MessageBox.Show("Hello"))
action.BeginInvoke(Nothing, Nothing)

In C#:

(new Action(() => MessageBox.Show("Hello"))).BeginInvoke(null, null);

Translated to VB

(New Action(Sub() MessageBox.Show("Hello"))).BeginInvoke(nothing, nothing)

does not compile. Syntax error when starting the line with a parenthesis.

Any solutions? If yes, what? If no, why not? Thanks!

I just tried this and got no issues:

Dim a = (New Action(Sub() MessageBox.Show("Hello"))).BeginInvoke(Nothing, Nothing)
