member this.InvokeCoreAsync : string * Type * obj[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<obj>
abstract member InvokeCoreAsync : string * Type * obj[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<obj>
override this.InvokeCoreAsync : string * Type * obj[] * System.Threading.CancellationToken -> System.Threading.Tasks.Task<obj>
Public Function InvokeCoreAsync (methodName As String, returnType As Type, args As Object(), Optional cancellationToken As CancellationToken = Nothing) As Task(Of Object)
