abstract member WaitFor : Func<bool> * string * Nullable<TimeSpan> * Nullable<TimeSpan> * Nullable<TimeSpan> -> unit
Public Sub WaitFor (predicate As Func(Of Boolean), Optional timeoutMessage As String = "Timed out waiting...", Optional timeout As Nullable(Of TimeSpan) = null, Optional retryFrequency As Nullable(Of TimeSpan) = null, Optional postTimeout As Nullable(Of TimeSpan) = null)
